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 on the structure of control and status bytes

For detailed information on the structure of a particular I/O module's

control/status bytes, please refer to that module's manual. Manuals for each

module can be found on the Internet at www.wago.com.
