Thank you! Do you have other method to solve this problem!

It is urgent for me. Can somebody help me. Delta engineer who focus on modbus tcp can tell me where the unit number is, so I can change the number from 0 to 2. My camera always use Modbus Rtu, it also support Modbus tcp, in modbus tcp, it need unit number.

Dear supports, I want to use clipper to read datas from camera by Modbus TCP. I already install the modbus tcp bin file, I am sure the Modbus TCP on clipper and Camera are ok, because they can connect with PC ModScan tool (a Modbus client and server software). I also use wireshark to watch the datas. I set the modbus setup follow delta manual. In my test: Clipper sent frame datas: 00 00 00 00 00 06 00 03 03 E8 00 08 00 00 00 00 00 06 is default 00 is the unit number, clipper want to connect the device 03 is FC03, read multipul register 03 E8, the modbus ref 1000 00 08 ,the length of words 8 Problem: the unit number of Camera is 2( this number is fixed by camera compny), so can clipper change the unit number 00 to 02? I hope clipper will sent frame datas like these: 00 00 00 00 00 06 02 03 03 E8 00 08 If that, clipper will read datas form camera successfully. Thank you!
