EtherCCM not reading / writing to PLC

[marc.turcotte]

I get the "Successfully wrote 1 byte of data" message, but its not writing to the PLC at all...?!

Just to make sure i tried the right thing with the Host Ethernet CCM Transaction program... here is what i entered for C1003 writing:

-Write checked
-Data type : Output
-Size : 1
-Start Address (Hex) : 203
-Data to write : well i tried 1, 01, 11, 10 just in case...


I tried reading a value (C1000), that is alway true, and when i try to read address 200 (hex) , i get 00.


Thanks for your help!
