5.3.5 Specialty Modules
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
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.
The Specialty Modules represent as analog modules.
For this, the process input data of the Specialty Modules seize one Instance
per channel in the Analog Input Point Object (Class 0x67) and the process
output data seize one Instance seize one Instance in the Analog Input Point
Object (Class 0x67) per channel in the Analog Output Point Object (Class
0x68).
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.
The specialty modules represent 1x6 bytes input data and seize 1 Instance in
Class (0x67).
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:
