I have a PLC Quantum with NOE771 card communicating with HMI-CITECT.

When I program with ProWORX NxT 2.2 and for example when I execute "Search Address", and PLC is proccesing, be stop PLC (CPU with 8 flashes) and Proworx show "CHECKSUM BAD....ERROR CODE 0200Hex".

 

Please precize your config:
NOE77100, 101, 110, 111 and its firmware rev

CPU and its firmware rev
any other Option module
to give exact solution.

 

I have CPU 43412A firmware 1.24, 2 NOE77100 kernel and firmware 3.0. Proworx NxT V.2.2s8

We input via proworx by Ethernet

Main Rack configuration:
CPU
NOM211
CRP811
CRP811
NOE771
NOE771
ACI030
ACI030
ACI030
CPS114

I changed old 42402 for 434 and now I can´t input 424 with Proworx, I have error CRC. via modbus

 

Some opinion?
