System 800xA 5.1 Integration using PLC Connect in system 800xA 188.8.131.52
We are trying to integrate some signals from an existing System 800xA version 5.1 FP4 rev D that is in a different domain from the System 800xA version 184.108.40.206 that we are using for an expansion project. We have network connection, and when we use a third party software to access the OPC Surrogate we can see it and see the information, but when we try to use the PLC connect we get the authentication errors showed in the attached image.
In the manual there is not an specific procedure for this case, so we are trying a combination of the cases that are described in the manual.
Please your advice.
Depending on how your domain security policy is set up, you may be able to enable remote login for that user to that machine. Or you may be able to change the account used by PLC connect. Bear in mind that allowing service accounts with full administrative rights *AND* well known passwords to log in remotely to any machine, is not really a great idea.
