I am trying to communicate to a Rockwell Micro820 PLC from ScadaMobile but get the following error – Validation Failure: An E/IP session was registered on the remote device but a controller could not be reached (Wrong controller slot number?). I have tried using the eip/native and eip/pccc protocols, but have had no success. Any Ideas?
The Validation Failure suggests that you don’t have a tag assigned to the Connection Validation.
are you using ScadaMobile or HMI Draw?
from the ScadaMobile Manual:
Note also that ScadaMobile performs a Validation Code security check before any other attempt to access other tags is made, therefore, it is mandatory to have a tag named “SMValidationCode” of type INT in your PLC for communications to work.
if you’re using the EIP/PCCC Connection.
Any INT value. This tag must be present in order for ScadaMobile to communicate. You may have to create a Data File number 98 of type Integer with at least 1 element
I am using ScadaMobile.
I have used ScadaMobile on ControlLogix and Micrologix PLC’s in the past with no issues, this is the first time using a Micro820. It seems like it cannot find the Micro820 as the error message says “(Wrong controller slot number?)”. I have configured the SMValidationtag in the global variables of the Micro820.
I am trying to communication with Micro logix 850. Since this PLC work on native symbols, can you please confirm will it be able to communication EIP/PCCC. if yes then how would I create data file number 98 as in CCW address are not created. In that case how to create a Data File number 98 of type Integer with at least 1 element. or please guide better option for communication with Micro logic 850 with HMI DRAW APP.
