Gambit Posted January 6, 2020 Report Posted January 6, 2020 Can you post your GX settings as well for ethernet and the port ? Also do you get an error in your ethernet diagnostics from the Q04UDE?

Gambit Posted January 6, 2020 Report Posted January 6, 2020 Looks like you're almost there: The number of points for a command specified by a connected device exceeds the maximum number of processing points (number of processes that can be executed per communication) for each process. Addresses from the start address (start device number and start step number) to the specified number of points exceed the largest addresses (device number and step number) for each process. Can you reduce the number of device points. Change H800(2048) end of you're command
lucifersaki Posted January 6, 2020 Author Report Posted January 6, 2020 I tried it and it didn't work. how can i do?
Gambit Posted January 6, 2020 Report Posted January 6, 2020 (edited) Did the Error on ethernet change ? So this is what you want to do right :0104 0000 640000 A8 0300 Reads word devices in units of one point. start adres 100 Device = D 3 points your screen capture has this...??? 0104 0100 640000 90 0800 Reads bit devices in units of one point. start adres 100 Device = M 8 points Edited January 6, 2020 by Gambit
