The output modules represent 8x2 bytes and seize 8 Instances in Class (0x68).
13.3.5 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 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 lies in the low byte for the fieldbus
coupler/controller with EtherNet/IP.
Information about 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:
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).
