It remains to be noted that in new versions, the PLC security is enabled by default. In Vijeo it is necessary to enter the same username/password for the HMI to have access to the PLC.
Hello, your comment it’s very interesting. I can’t communicate HMI with PLC, what ever I do, it doesn’t connect, so you mean that the application (runtime) must be blocked with an user and password, so communication can be established? or what kind o user and password do you mean ? Thank you in advance for your help, I’ve been dealing with this problem for 3 days 😢
Hello. When you configure the CPU you have surely set an access username and password. The same one that is used to connect to the PLC. You must put that username and password in the HMI connection driver.
@@claudio1371 yes, I sat an user and password for the PLC, but, where in HMI communication driver? I don’t see an option to set a user and password. I’m using SoMachine protocol by the way.
