Width Output Module
Two module types exist for the PWM output module:
Type of module Description
Substitute I/O modules
PWM
2-Channel PWM output module,
16-Bit signed process value per
signal channel
PWM_EM
2-channel PWM output module,
16 Bit input and output data plus
control and status byte per signal
channel, access to the register
structure using cyclic data
exchange
75x-511
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).
