Figure 2-7 Interface between PLC and axes/spindles/drives
2.6.3 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 from the machine control panel, for example, which
have to be taken into account by the HMI software. This group of signals includes, for
example, display actual values in MCS or WCS, key disable, etc. These are exchanged via a
separate HMI interface data block (DB19).
