2.6.2 PLC/MMC interface
General
The following groups of functions are required for the PLC/MMC interface:
• Control signals
• Machine operation
• PLC messages
• PLC status display
Control signals
In some cases, signals are input via the machine control panel and must be taken into
account by the MMC. This group of signals includes, for example, display actual values in
MCS or WCS, key disable, etc. These are exchanged with the MMC via a separate interface
DB (DB19).
