What I don’t get is how some of the command is correct but the rest is all wrong.
ASAParticipantYes it works correctly on windows i have tested the whole system on windows and it works.
Asa
ASAParticipantOk with the info above I have adjusted the .xml file address to 10 to see if there was a change in the signals received there was
The program log states it sent : 64 04 00 0A 00 16 58 33
That is correct howeverIn reality it sent :64 04 80 85 80 8b AC E6
Asa
ASAParticipantThe only error in the log is as follows it is listed multiple times
Date and time communication session with device 100 “A/W PLC”, type kpmodbus address 100 call number 100
Request element group
Send (8): 64 04 00 0A 00 16 58 33
Receive (0/5) :
Communication errorNow the device was not attached however it would not work anyway with those registers as they are unused.
Hope this helps
Asa
ASAParticipantHi
I should clarify the info I sent you was from a third party software looking at the signals recived by com port the problem I am haveing is the modbus first register is not the one I typed in if I change it the out put allso changes however it is all over the place the no of registers is allso wrong however all other relevent data is correct eg the device Id and function code as for the log ill attach it bellow.
