Currently I have issue for the "Value could not be written to PLC" which the value I entered from HMI. The HMI show the error code $190011. I already change the PG/PC interface but the error still popup. The HMI tag link with DB tag in PLC program also not change when I changed it through HMI. Regards, Amir

Check the systemalarms after restarting the HMI Runtime, do you get a connected or disconnected systemalarm? Do other tags work? Which FW does the PLC have? Bye Murof
