Overview of the F-DIs

Description
Failsafe digital inputs (F-DI) consist of two digital inputs. The cathode of the optocoupler is
routed to the second digital input in order to allow the connection of an M-switching F-DO
output (the anode must be wired to 24 V DC).
Parameter p10040 is used to determine whether an F-DI is operated as NC/NC or NC/NO
contact. The status of DI can be read at parameter r10051 for the drive objects TM54F_MA
and TM54F_SL. The same bits of both drive objects are logically linked by AND operation
and return the status of the relevant F-DI.
The signal states at the two associated digital inputs (F-DI) must assume the same status
configured in p10040 within the monitoring time set in p10002.
IN order to enable forced dormant error detection, connect the digital inputs of F-DI 0 ... 4
with the dynamic voltage supply L1+ and the digital inputs with F-DI 5 ... 9 to L2+ (for
additional information on forced dormant error detection, refer to the corresponding function
description in the chapter "Extended Functions").
