System Status information into variables

[Hanes]

Hi all,

I would like to ask if in Mervis IDE (Unipi 1.1) there is any possibility to import information about the system into variables and then display it on the HMI.
Specifically, I would like to further process information about wrongly transferred packets via the ModBus USB port.

Thanks
Jan

Hello,
It is possible to use commerror variables, they state if there is an issue with the communication. However, note that those variables must be used in program (connecting them to themselves is enough, see the bottom of task types), in order to use them elsewhere.

Best regards,
