Hi,
It looks Like any ID higher than 09 causes the ethernet port to become unresponsive.
I have re-ID the PLC's with this problem with the ID range 01 - 09, although one PLC would take longer to respond the higher the ID i.e. if the ID was 07 it would ping in 400ms and drop 50 of the packets, now its set to 02 i get all four packets and the response is 5-15 ms???
I have used the following setsystem command for the HMI:
SETSYSTEM 8, &H0001 ' Set Comm Port 1 ti ID 1 for RL
This works on all PLCs r76A to r78A.
For future systems i will use the:
'SETSYSTEM 8,&H0375 '+ DM[66] ' Set Device ID &h03 = cOMM4 ETHERNET IP
But going back to my original request, how to i convert the dec data from the DM field into hex?
Cheers
