10.8
Reassigning parameters during operation
Introduction
You have the option of reassigning the parameters for the ET 200SP I/O modules during
operation.
Changing parameters during operation
You make the parameter settings of the I/O modules using data records. Each I/O module
has a separate data record. The instruction "WRREC" applies the changed parameters to
the I/O module.
If you are using the CPU as an I-device, you reassign the parameters of the I/O modules via
the I-device.
Note
If you write data records from the user program to the modules of the distributed I/O, make
sure that these modules actually exist and are available. You can evaluate OB83 for this
purpose. After inserting a module, the CPU does not call OB83 until the module has started
up and its parameters are assigned. This ensures the execution of the data record
operations without errors.
Note
You need to transfer the new parameters with the "WRREC" instruction after a POWER
OFF/POWER ON of the ET 200SP.
Instruction for parameter assignment
The following instruction is provided for assigning parameters to the I/O module in the user
program:
