• RSet: Reset input for error acknowledgement

• LOCK: Lock switch position
LOCK = 0: Switch position unlocked
LOCK = 1: Switch position locked
If the switch position changes, an error will be

Permitted time range: 1 ... 2047 ms
INFORMATION
If possible you should use the PSS(1) DI2 as input module.
If this is not possbible, the inputs must use test pulses.
Output parameters
• FG: Enable flag bit
FG = 1:
Enabled (no errors)
i.e. existing errors were reset via
RSet and
only one input ( S1... S8) = 1.
• BA: Operating mode,
Output parameter: Byte format (8 Bit)
If the input signal is faulty, no bit will be set in output byte
BA.
