HMI panel communication
If you had one or more HMI panels (Page 32) connected to your S7-1200 V3.0 CPU, the
communication to the S7-1200 V4.2 CPU depends on the type of communication you use
and the firmware version of the HMI panel. Recompile and download your project to the CPU
and the HMI and/or update your HMI firmware.
