7 EZ 800/EZD Control Commands

Data exchange procedure

The Control commands 9 bytes module allows extended data

exchange of the EZ800 and the EZD on the PROFIBUS-DP

communication bus. This allows you to transfer services from

the following areas:

• Read/write date and time (Page 95)

• Read/write image data (Page 99) and

• Read/write function block data (Page 120).

A data exchange procedure is required in order to ensure the

safe exchange of data via PROFIBUS-DP from master to

slave and vice versa.

Attention!

While a control command is being executed, the input and

output data will remain in the state before the control

command was called. Only after the “Control commands”

data exchange has been completed, will the I/O data be

refreshed.

Caution!

Only those values specified for the command code should

be used.

Check the values that you write in order to avoid

malfunctions.

Requirement:

The “Control commands 9 byte” module must have been

selected.

The master initiates the data exchange of the control

commands and the addressed slave responds.

During communication 9 data bytes (byte 0 = toggle byte,

bytes 1 to 8 information bytes) are sent via PROFIBUS.

The basic telegram structure is shown in the following

diagram.

EZ800/EZD Control Commands

Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8

Byte 0 – Toggle byte

Byte 0 is used to activate the sending of a control command

with the toggle function.

Bit

01 /861

0/1

hex

fixed

Procedure

XTo send a command, bit 7 must be toggled, i.e. set either

from 1 to 0 or from 0 to 1.

XThen poll the toggle bit for the coupling modules response

until it has the same status as the toggle bit sent. This status

indicates to the master that the response to the sent

command is valid.

XDo not send a new command until you have received a

response (changing of the toggle bit), otherwise the

response of the previous command will be overwritten

before it can be read.

In order to use input/output data and control commands

simultaneously:

Only after the “Control commands” data exchange has

been completed, will the I/O data be refreshed.

All specified commands and parameters must be

transferred in hexadecimal format.

The following tables show the different control commands

possible. These essential control commands fall into three

essential categories – real-time clock, image and function

blocks.

Read/write image data

Reading and writing local analog output QA1

The commands provided can be used to access the local

analog output of the EZ800 or EZD basic unit. When writing to

the analog output, however, the value will only be output

externally if the device concerned is in Run mode and the

image concerned has not been overwritten by actual program.

EZ800/EZD Control Commands

Reading local P buttons

The local P buttons are the display cursor buttons of the

EZ800/EZD basic unit. You can scan the buttons in both Run

and Stop mode.

Ensure that the P buttons are also activated via the

SYSTEM menu (in the basic unit).

Only one byte has to be transferred for the P buttons.

EZ800/EZD Control Commands

Reading receive data network RN1 .. RN32/send data

network SN1 .. SN32

EZ-NET allows a point-to-point connection to be implemented

between the individual NET stations. The RN and SN data are

used for the data exchange (see the EZ800 manual and EZD

manual).

The RN SN data of the local device (Index = 0) to which the

EZ204-DP is fitted cannot be scanned. In this case the

command would be denied with the 0C_hexsignal.

blocks provided in the EZ800 manual and the EZD manual.

General notes

Always note the following when working with function blocks:

• The relevant data is transferred in Intel format. In other

words, the first byte is the low byte (Byte 5) and the last byte

(byte 8) the high byte.

• The maximum data length is 4 bytes. All values must be

transferred in hexadecimal format.

• All 32-bit values are treated as signed values. When

transferring 32-bit values, ensure that the appropriate value

range is suitable for long integers, i.e. signed.

32-bit value: –2147483648 .. 0 .. +2147483647
