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 bidirectional 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.
The control/status byte always is in the process image in the Low byte.
Information to the structure of the Control/Status byte
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: http://www.wago.com.

Counter Modules

750-404, (and all variations except of /000-005),
753-404, (and variation /000-003)
The above Counter Modules have a total of 5 bytes of user data in both the Input
and Output Process Image (4 bytes of counter data and 1 byte of control/status).
The counter value is supplied as 32 bits. The following tables illustrate the Input
and Output Process Image, which has a total of 3 words mapped into each image.
Word alignment is applied.
