Potential Supply Modules

The group of potential supply modules is divided into 2 types of modules:
Type of module
In case there is no diagnostics data prepared in the input image, potential
supply modules supply a provider status (IOPS) to the I/O controller. If the
input data is available in the input process image then the consumer status
(IOCS) is received from the I/O controller.
The following table shows a list of the number of bytes for the individual
modules that are allocated in the respective process image (PA) and the
telegrams (TLG) in the direction of transmission and reception (Tx, Rx).
