Using com port 1 on a dl06 for modbus
Working on an existing dl06 program. It is hooked up to a Panasonic gt35 screen. My issue is trying to find the modbus address on the C0 output. I have the address from the hmi but can't find where it is stored in the program. The pic of the hmi screen shows modus address. The pic of the program shows the rung.
The DL06 Micro PLC User Manual starting on page 4-12, explains the ways a Modbus address can be specified, and also how to calculate the Modbus address for the various PLC memory types, including "C" bit "Coil" Modbus Data type. The manual can be downloaded from the website.

We found it helpful to use software tools for testing Modbus communications. We have used Win-Tech ModScan32 and ModSim32, but there are also other software packages out there.
