13.7.2 Interface PLC/HMI
General
The following groups of functions are required for the PLC/HMI interface:
• Control signals
• Machine operation
• PLC messages
• PLC status display
Control signals
Some control signals are signal inputs, for example, via the machine control panel, which have to be taken into
account by the HMI. This group of signals includes, for example, display actual values in MCS or WCS, key
disable, etc. These are exchanged with the HMI via a separate interface data block (DB19).
