Analog Output Modules

The hardware of an analog output module has 16 bits of measured analog data per

channel and 8 bits of control/status. However, the coupler/controller with

MODBUS/TCP does not have access to the 8 control/status bits. Therefore, the

coupler/controller with MODBUS/TCP can only access the 16 bits of analog data

per channel, which are grouped as words and mapped in Intel format in the Output

Process Image.

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.

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.
