3.1.5.3 Example of a Process Output Image
WAGO-I/O-SYSTEM 750
ETHERNET TCP/IP
The following figure is an example of a process output image. The
configuration includes 2 digital and 4 analog outputs. Therefore, the process
image has a total data length of 5 (4 words for the analog data and 1 word for
the digital outputs). When using MODBUS protocol, output data can be read
back with an offset of 200

Note
All output data over 256 words can be read back with an offset of 1000
(0x1000) added onto the MODBUS address.
