14.1.6.2 2-Channel Pulse Width Modules
The group of 2-channel pulse width output module has one module type divided
into two submodule types.

2-Channel Pulse Width Output Modules,

plus all variations
Pulse width output modules receive the provider status (IOPS) from the IO
controller and supply it with the consumer status (IOCS) of the received output
information in case only the actual user data is exchanged. If all existing
information is available in the process image of the inputs and outputs, the process
data qualifiers are also transmitted in the opposite direction.

14.1.6.3 Distance and Angle Measurement Modules
The group of distance and angle measurement modules includes three module

1DII
Digital Impulse Interface,

and status byte per signal channel, access to the

75x-635
For the distance and angle measurement modules, the provider and consumer
status (IOPS, IOCS) of the input or output information are exchanged between the
IO controller and IO device in both directions. With the SSI interface 75x-630,
there is also an option to transmit the input data of the transmitter only.
