5.2.1
Safety controller with two ESPE
You can completely configure a safety controller (1) with two ESPE connected via EFI (2a
and 2b) from the safety controller.
If you connect the PC to the RS-232 interface on an ESPE (2a), you can only configure this
device. Although the safety controller (1) and the second ESPE (2b) are visible in the CDS,
they cannot be configured and diagnostics are not possible.
