Module Tags Appendix A
Channel Configured for
Modbus Master
This screen capture shows the tags that are described in the following tables.
Input Tags
In the following table, the xx in the tag names represents the channel number
because the module has two channels, and both channels support the use of
Modbus Master.
TIP The yy in the tag names represents the Modbus Master command number
and the zzzzzz represents the Modbus data address.
