The global variable provides values to the user program.
To get additional options for programming fault reactions in the user program, assign global
variable to Counter
.Error Code
and
Module Error Code
. Refer to the manual of the compact
system or module for more details on how to use the error codes and other parameters of the
counter input.
Use of Digital Inputs
To write a value in the user program to a digital output:
1. Define a global variable of type BOOL containing the value to be output.
2. Enter an appropriate initial value, when defining the global variable.
3. Assign the global variable the
Value [BOOL] ->
channel value of the output.
4. In the user program, program a safety-related fault reaction using the error code
-> Error
Code [Byte].
The global variable provides values to the digital output.
To get additional options for programming fault reactions in the user program, assign global
variable to
DO.Error Code
and
Module Error Code
. Refer to the manual of the compact system
or module for more details.
Use of Analog Outputs
To write a value in the user program to an analog output
1. Define a global variable of type INT containing the value to be output.
2. Enter an appropriate initial value, when defining the global variable.
3. Assign the global variable the
Value [INT] ->
channel value of the output.
4. In the user program, program a safety-related fault reaction using the error code
-> Error
Code [Byte].
The global variable provides values to the analog output.
To get additional options for programming fault reactions in the user program, assign global
variable to
AO.Error Code
and
Module Error Code
. Refer to the manual of the compact system
or module for more details.

Configure Line Control
The pulse delay for line control is the time between setting the pulsed outputs to FALSE and the
latest possible reading of the signal on the corresponding input.
The default value is set to 400 μs. This value might need be increased if longer wires are used.
The maximum value is 2000 μs.
The minimum time for reading all inputs results in
pulse delay x number of pulses.
The pulsed outputs are usually set to TRUE and change to FALSE in succession for the
duration of the pulse delay once per cycle.
