Pulse Width Output Module

Two module types exist for the PWM output module:
Type of module
PWM output modules receive the consumer status (IOCS) from the I/O
controller and supply it with the provider status (IOPS) of the existing output
information in case only the actual user data is replaced. If all existing
information in the input and output image is made available then the process
data qualifier is additionally transmitted in the opposite direction.
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).
