There is an updated T100MD+ modbus mapping document that you can download from the following link:
http://www.tri-plc.com/appnotes/modbus-map.pdfThis document provide the mapping of the bit I/Os to the MODBUS bit addresses. However, we treat the MODBUS bit address as from 0 to 2048 range only and we treat all I/O bits the same regardless of whether it is an input, an output, relay, timer or counter bit. Inputs are mapped to bit address 1 to 256. Outputs are mapped to bit addresses 257 to 512, etc.
It seems like the GT-01 panel uses the first digit to represent the I/O type, yet it uses zero offset to represent the bit which is not quite MODBUS like. Anyway, please try the following:
Input 1: 100000
Input 2: 100001
.....
Input 96: 100095
Output 1: 000256
Output 2: 000257
....
Output 96: 000352
Etc.
