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!
