Chapter 1 StateLogic Processor Description  
1
The State Logic Processor (SLP) is a module which inserts into a Series 90 -30 PLC chas-  
sis. This module has the State Engine operating system to execute State Logic control  
programs produced by the ECLiPS programming software package.  
The SLP exists together with a CPU module in the Series 90 -30 PLCs. The CPU must be  
a model 331, Revision 3.03 or higher. The CPU may execute a Relay Ladder Logic Pro-  
gram at the same time the State Logic Processor is executing a State Logic Program. The  
SLP manipulates the CPU memory space and the CPU controls the I/ O during its normal  
cycle of operations. More than one SLP can be installed in one Series 90-30 PLC system,  
although the SLP must be installed in the main rack with the CPU.  
The software products, ECLiPS and OnTOP, are the user interfaces to the SLP. ECLiPS is  
a program development and on-line monitoring software product which runs on an  
IBM-PC compatible computer. OnTOP, the On-Line Troubleshooting Operator Pro-  
gram, also runs on an IBM-PC compatible computer. For questions about programming  
or on-line functions, see the ECLiPS or OnTOP User s Manuals.

Physical Description  
The SLP occupies a single slot in the Series 90-30 rack, communicating with the PLC CPU  
over the backplane to perform its many control functions. The SLP controls and accesses  
CPUI/ O, register, and system data.

Figure 1-1. SLP in Series 90-30 Chassis  
The 90-30 SLP uses an 8 mHz 80C188 microprocessor and has two serial ports, port 1 is  
and RS-232 port and port 2 is an RS-422/ 485 port. One port is designated the program-  
ming port, to be used to communicate with ECLiPS or OnTOP. The other port may be  
configured to be a CCM port, communicating to a host computer using the CCM proto-  
col. See the section on Serial Communications for more information on using the serial  
ports.  
There are three LED indicators located at the top front edge of the SLP. The top LED is  
the status indicator for the SLP. During power-up this LED flashes while the SLP is run-  
ning its diagnostic checks. If this LED is off, either the power is off, there is some hard-  
ware malfunction of the SLP, or there is no CPU present in the Series 90-30 PLC system.  
When the LED is on, the SLP is functioning normally.

Operational Description  
The State Logic Processor (SLP) uses areas in the CPU memory for I/ O references and  
Register values. The SLP and the CPU communicate this information over the PLC  
backplane.  
When a Ladder Logic control program and a State Logic control program are running at  
the same time, the State Logic and Ladder Logic programs should not be controlling the  
same outputs. The SLP cannot control an output that is being controlled by the CPU,  
since the 90-30 CPU always takes precedence when both processors are controlling the  
same outputs.  
All of the outputs used in the State Logic program should be selected to be contiguous if  
system response time is important. Outputs being non-contiguous causes the scan rate  
to increase significantly.  
When changing outputs the SLP writes to a byte of I/ O bits at a time, so that any the SLP  
actually controls eight ouputs at a time. Therefore, if some outputs of a byte are not  
named in the SLP program, ECLiPS issuses a warning that the other outputs in that byte  
are changed when the program executes.

This chapter describes how to install the SLP into a Series 90-30 PLC rack. There is also a  
section describing maintenance considerations.  
Selecting the Right Slot  
The SLP can be installed in any unused slot in the CPU rack of the Series 90-30 PLC if the  
following rules are followed:  
1. Configuration created by Logicmaster must match the physical location of the  
modules. Configuration faults are logged in the PLC fault table.  
2. For the 90-30 SLP all the slots between the SLP and CPU must be occupied. If any  
slots between are empty the SLP cannot communicate with the CPU. The SLP must  
be in the main rack with the CPU.  
Inserting the SLP  
Follow these steps to insert the SLP into the Series 90-30 rack:  
1. Power down the Series 90-30 PLC system  
2. Locate the desired rack and slot.  
3. Slide the 90-30 SLP completely into the slot.  
4. Press down firmly to lock the module in place, but do not use excessive force.  
5. Power up the PLC rack. The Status LED flashes during power-up diagnostics. The  
LED comes on steady when the SLP is ready for operations.

Configuration  
Use the Logicmaster 90-30 configuration software to add the SLP to the Series 90-30  
I/ O configuration. This software is used to describe the modules present in the PLC  
racks. Rack and slot location and other features for each module are entered by com-  
pleting setup screens that describe the modules in a rack.  
Figure 2-1.  
From the main menu of the Logicmaster 90-30 configuration software, press I/ O <F1>.  
The screen displays a representation of the modules in a rack. To add an SLP to the con-  
figuration, highlight the desired slot, then press Other <F8> and then PCM <F1>.  
Now press Zoom <F10> to view the current configuration. Press <Enter> to enter the  
highlighted catalog number and display the PCM detail screen.  
Now set the Configuration Mode to PCM CFG for the 90-30 SLP. First highlight the Con-  
fig Mode option and repeatedly press the <Tab> key until PCM CFG is displayed on the  
screen. The serial ports are under program control and the parameters are initialized by  
the State Logic Processor.  
Now press the <Esc> key to save the configuration and return to the rack display. The  
display should now show a PCM in the correct slot. Send the configuration to the PLC  
CPU and the configuration is complete.  
During program execution the CPU must be in run mode with the outputs enabled. Use  
LM90-30 to set the status of the CPU before executing the State Logic program.

Battery  
The State Logic Processor comes with a 3 volt lithium battery (IC697ACC701) to maintain  
memory through a power cycle. If the battery charge becomes low, a fault is set in the  
fault table. These faults can be monitored by the State Logic program.  
To replace the battery, connect the new battery to the extra set of battery connections  
then disconnect the old battery. A Product Safety Data Sheet for the battery is available.  
Order from GE Fanuc using number GFK-0633.

This chapter provides procedures for diagnosing State Logic Processor (SLP) problems.  
If these procedures do not solve the problem, contact the GE Fanuc Hotline  
(1-800-828-5747) for assistance.  
Status LED is not ON Steady  
1. Check that power is supplied to the I/ O rack housing the SLP. Try removing and  
reinstalling the SLP.  
2. Cycle power to the SLP, then press the reset button for more than 5 seconds.  
3. Turn the power OFF and disconnect the battery and short the SLP battery terminal  
connection points to clear the SLP. Reconnect the battery, turn ON power again, and  
reset the SLP.  
4. Check that the CPU is functioning properly by checking its “OK” LED.  
5. Check that there are no empty slots between the CPU and the SLP. If there are  
empty slots, the Status LED blinks continuously.  
6. If the Status LED is still not ON, try to download a program from ECLiPS or OnTOP.  
If you can connect with the SLP and download a program, then the Status LED is  
faulty.  
7. If you get a message that ECLiPS or OnTOP cannot connect to the controller, then  
check the fault table in the CPU using Logicmaster 90. If there is a fault “Bad or  
missing module”, then the SLP is faulty and must be returned for repairs.  
8. If there is no fault then contact the GE Fanuc Hotline for assistance.  
Serial Communication Problems  
This section is split into two parts, communication problems to ECLiPS or OnTOP and  
problems with other serial devices.  
3-1  
GFK-0726B

Communications Problems with ECLiPS or OnTOP  
1. Check that the serial cable used conforms to one of the types specified for  
communications to the SLP ports. Check that the cable is firmly secured at both  
ends.  
2. When there is a communications problem, a message indicating problems  
connecting to the controller is displayed together with some options. Select the  
Change Host Comm Port Settings” option to check the computer port being used  
and the baud rate. The default SLP baud rate is 19.2K.  
3. The SLP programming port may have been changed. ECLiPS and OnTOP must be  
connected to the designated programming port. The default programming port is  
Port 1 but can be changed by ECLiPS or OnTOP. Make sure the serial cable is  
connected to the current programming port.  
4. The SLP serial port configuration may have been changed. These parameters can  
only be changed by Statements using the Set_Commport keyword in the State Logic  
program. Reset the SLP to return the SLP serial port parameters to their default  
state. If the program is setup to start running automatically and the program  
continues to change the serial port parameters after the reset switch is pressed, turn  
off the power to the SLP, remove the battery, and short the SLP battery leads to reset  
the SLP.  
5. Port 2 of the 90-30 SLP is an RS-422/ 485 port and Port 1 is an RS-232 port. Make sure  
that the host computer serial port setup matches the SLP port for RS-232-RS-422/ 485  
option.  
6. If there is still no communication between the SLP and OnTOP or ECLiPS then call  
the GE Fanuc Hotline for assistance.  
Communications Problems with Another Serial Device  
1. Check that the serial cable used conforms to one of the types specified for  
communications to the SLP ports. Check that the cable is firmly secured at both  
ends.  
2. Make sure that the serial port parameters of the serial device match the settings of  
the SLP. The default settings of the SLP are 19.2K baud rate, 8 data bits, 2 stop bits,  
and no parity.  
3. Make sure the RS-422/ 485-RS-232 standards are the same for SLP and the serial  
device  
4. When connecting some device to the programming port, make sure that you exit  
ECLiPS or OnTOP normally before disconnecting from the SLP.  
5. If there are still problems contact the GE Fanuc Hotline for assistance.

the two serial ports. Each of these ports can send and receive serial data independent  
from the other. Port 1 is an RS-232 port and port 2 is an RS-422/ 485 port. There is only  
one 25-pin connector on the SLP which provides access to the connections for both  
ports. The SLP comes with a WYE cable which provides one 25-pin connector for each  
port.  
ECLiPS and OnTOP must communicate with the SLP through the programming port.  
Either port can be the programming port, but port 1 is the default programming port.  
When ECLiPS or OnTOP is not connected to the SLP, the programming port can be used  
to communicate with some other serial device. To properly set the programming port to  
communicate with another device, exit ECLiPS or OnTOP normally before disconnect-  
ing from the SLP.  
Either of these ports may also be a CCM port. The CCM port uses the GE Fanuc CCM2  
protocol for all communications. This protocol is used for connecting the SLP with a host  
computer which collects data and changes data in the SLP. Typical CCM uses are con-  
necting to a graphical user interface program such as CIMPLICITY or for custom host  
interaction with the SLP.  
The SLP is always a slave to the host, i.e., all communications are initiated by the host  
computer. The SLP may be one of several devices on a CCM network. The CCM port is  
always the port that is not designated as the programming port. The CCM port is a nor-  
mal RS-232 or RS-422/ 485 port when CCM communications are not enabled.

Programming Serial Communications  
The program communicates through two ports using WRITE and READ terms. For ex-  
ample:  
State: Get_Setpoint  
Write “Enter New Setpoint” to Operator_Panel.  
Read SetPoint1 from Operator_Panel, then go to Check_Setpoint State.  
The Write Term sends the string of characters, Enter New Setpoint, to the port defined as  
the Operator_Panel. This same port is then monitored for input by the Read Term in the  
next Statement. The variable Setpoint1 is set to the value entered through the specified  
port.  
In this example the WRITE and READ term information is directed to a particular port.  
Operator_Panel in this case is defined in ECLiPS as Port 1 or Port 2. Use the ECLiPS, DE-  
FINE or LIST menus to make the port definitions. The default names are Port_1 and  
Port_2.  
The Read and Write Terms may also be used without being directed to any particular  
channel, for example:  
State: Choose_Recipe  
Write “Enter Recipe Number ”.  
Read Recipe_Number, then go to StartBatch State.  
Since no port is specified in this example, information is sent to the programming port.  
For a more detailed discussion of programming serial input and output, refer to the Ref-  
erence Section of the ECLiPS User ’s Manual.

Serial Port Setup  
There are several serial port configuration options. Some of these options are set using  
ECLiPS or OnTOP, and others can only be set by an executing State Logic program.  
ECLiPSor OnTOP Options  
The options available in the ECLiPS or OnTOP menus to change the configuration of the  
SLP serial ports are displayed below.  
The options available in the ECLiPS or OnTOP menus to change the configuration of the  
SLP serial ports are displayed below.  
Each of these options is set in the State Engine Configuration Menu selected from the  
Debug Mode Project Menu in ECLiPS or from the Controller Option in OnTOP.  
Programmable Setup Options  
On power up the serial port parameters are set to their default settings. These settings  
may be changed by using the Set_Commport programming keyword in the control pro-  
gram. The Set_Commport keyword and parameters must be executed by the control  
program to change the serial port settings. Just changing the parameters in the ECLiPS  
serial communications setup form does not automatically change these settings.  
After the SLP serial port parameters are set, ECLiPS automatically enters the Set_Comm-  
port instruction into the program when the following selections are made. Select the  
LIST option from the program mode menu; then select the Communication Ports option.  
Highlight the appropriate port and press <Enter>. ECLiPS prompts whether to enter  
the port name only or enter reconfiguration data. After selecting Enter Reconfiguration  
Data, the Set_Commport keyword plus the instructions to change the serial port param-  
eters are entered into the ECLiPS program.  
These options affect the SLP serial port configuration only, not the ECLiPS or OnTOP  
serial port setup. The option to change the ECLiPS or OnTOP host computer serial port  
configuration is available only when there is some problem connecting ECLiPS or On-  
TOP to the SLP. The only options which can be changed on the ECLiPS or OnTOP serial  
port configuration are selecting COM1 or COM2 and changing the baud rate.

Serial Cable  
The State Logic Processor (SLP) is designed to work with two GE Fanuc standard serial  
cables. One cable is the Mini Converter Kit that comes with the ECLiPS. The other is the  
PCM to IBM-PC cable. Use the RS-422/ 485 serial cables to connect to Port 2, if  
RS-422/ 485communications are used.  
Mini Converter Kit  
ECLiPS comes with a serial cable kit that can be used to both connect the CPU with Lo-  
gicmaster and to connect the SLP with ECLiPS or OnTOP running on an IBM PC. This  
cable kit comes with three adapters:

The cable provided in the kit is terminated with two 9-pin connectors. One of the adapt-  
ers connects the 9-pin serial cable to the 15-pin serial port on the CPU (HE693SNP232),  
another adapter connects the serial cable to the 25-pin female Port 1 on the SLP  
(AD232/ 1-2), and the third adapter can be used to connect to a 25-pin port on the IBM  
computer running Logicmaster 90, ECLiPS, or OnTOP (HE693XTADP).

Other Cable Options  
Other cables that work with the SLP are the IBM-AT cable, IC697CBL702, and the Work-  
master II or PS/ 2 cable, IC697CBL705. The connector on the SLP end can be made to be a  
right angle connector, so that the SLP front cover can be closed and the cable brought

Custom Made Cables  
If you want to make your own cable to connect to some serial device, use the drawing of  
the SLP pin assignments and the cable connection drawings in the previous section for  
the required connections. Hardware flow control lines must be used when communicat-  
ing with the SLP using RS-232. The flow control lines are not used for RS-422/ 485 com-  
munications.
