SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
3-135
A PLC module that is compatible with the SIMATIC S7 315-2DP is used as the
PLC in the SINUMERIK 840D. Signals are processed according to what has
been programmed in the PLC user program (refer to Chapter 4, "Interface
signals for SINUMERIK 840D").
References: /FB/, P3, "Basic PLC Program"
The machine status is transferred to the monitoring comparators for specific
axes/spindles via the PLC inputs and the PLC user program.
The PLC SGE/SGA interface is mapped using the following axis/spindle-
specific data blocks:
