The CSE 925 is a single slot programmable controller
CPU which provides State Logic control programming
and floating point calculations. The CSE 925 can be
programmed in State Logic, Relay Ladder Logic, and
C to perform real-time control of machines, processes,
and material handling systems.

The AD641 software products are used to program
the CSE 925 in State Logic; the IC641 (MS-DOS) soft-
ware products are used to program in Relay Ladder
Logic and C. The IC641 (MS-DOS) software is also
used to perform all configuration functions for the
CSE 925.

The CSE 925 communicates with I/ O and smart op-
tion modules over the rack mounted backplane
(IC697CHS750, 782, 783, 790, 791) by way of the VME
C.1 Standard format.

Make sure that rack power is off.
Serial Port
Install the CSE 925 module in slot 1 of rack 0 (see
Figure 2).
The 15-pin D-connector provides the connection to an
RS-485 compatible serial port on the CPU as shown in
Figure 2.
Turn on power.
The module should power up and the top LED should
blink. When the diagnostics have completed successfully,
the top LED stays on and the second and third LEDs are
off. The fourth LED is off if the keyswitch is in the OFF
position. The CPU is now ready to be programmed.
The serial connection is made from the serial port on the
CPU to the serial port on the programming computer,or
other serial device, through the RS-422/ RS-485 to
RS-232 Converter (IC690ACC900) or RS-232 to RS-422
Miniconverter (IC690ACC901). This connection can be
made with available cables or you may build cables to fit
the needs of your particular application. See reference
3 for more information on serial communications.
After the program has been verified the toggle switch may
be moved to the appropriate operation mode position.
The LEDs indicate the position of the toggle switch,
memory protection status, and the state of the program.
Configuration
The IC641 (MS-DOS) software is also used to load the State
Logic operating system into the CSE 925 CPU module.
The operating system is provided on a floppy disk with
the CSE 925. The operating system is stored in flash
memory on the module. For information on loading the
operating system, see the State Logic Control System User’s
Manual.
The IC697CPU and I/ O system isconfigured with IC641
(MS-DOS) programming software. There are no DIP
switches or jumpers used to configure the system. The
CPU verifies the actual module and rack configuration
at power-up and periodically during operation. The
actual configuration must be the same as the
programmed configuration. Deviations are reported to
the CPU alarm processor function for configured fault
response. Consult Reference 1 for a description of
configuration functions.

Batteries
or
A lithium battery (IC697ACC701) is installed as shown
in Figure 1. This battery maintains program and data
memory when power is removed and operates the
calendar clock. Be sure to install the new battery before
removing the old battery. Specific indication of a low
battery state is detailed in Reference 2.
