• The PROFINET interface module supports a baud rate of up to 100 Mbps.
• Process and diagnostics data can be exchanged through the PROFINET interface module:
– Cyclic: Depending on the safety relay, the PLC can exchange 32 bits or 64 bits of process
data with safety relay.
– Acyclic: The PLC can query diagnostics data data from the safety relay. With Safety ES, the
diagnostics information can be displayed graphically.
Both options can be used at the same time.
