Specialty Modules - WAGO 750 Series Manual

When digital output modules are also present in the node, the analog output
data is always mapped into the Output Process Image in front of the digital
data.
2 Channel Analog Output Modules
750-550, -552, -554, -556, -560, -585, (and all variations)
4 Channel Analog Output Modules
750-551, -557, -559

3.1.5.4.5 Specialty Modules

WAGO has a host of Specialty I/O modules that perform various functions.
With individual modules beside the data bytes also the control/status byte is
mapped in the process image. The control/status byte is required for the bi-
directional data exchange of the module with the higher-ranking control
system. The control byte is transmitted from the control system to the module
and the status byte from the module to the control system.
This allows, for example, setting of a counter with the control byte or
displaying of overshooting or undershooting of the range with the status byte.
Further information
For detailed information about the structure of a particular module's
control/status byte, please refer to that module's manual. Manuals for each
module can be found on the Internet under:
