Parameter data record

B.1

Dependencies for the configuration

When configuring the I/O device, the parameter settings are independent of each other.

Structure of data record 128 for I/O device parameter assignment

With data record 128, you can reconfigure the I/O device in your user program, regardless of
your programming. This means that you can use all the functions of the I/O device even if you
configured it with a GSD file.
Parameter assignment in the user program
You can reassign the parameters of the I/O device in RUN. For example, you can change the
hardware interrupts of individual channels in RUN without this having an effect on the other
channels.
Changing parameters in RUN
The "WRREC" instruction is used to transfer the parameters to the I/O device using data
record 128. The parameters set with STEP 7 are not changed in the CPU by this action. After a
restart, the parameters set in STEP 7 are still valid.
Output parameter STATUS
If errors occur during the transfer of parameters with the "WRREC" instruction, the I/O device
continues operation with the previously valid parameter assignment. The STATUS output
parameter contains a corresponding error code.
The instruction "WRREC" and the error codes are described in the online help of STEP 7.
