Safety I/O Module and TÜV Requirements F-5
Configuration of the 1732DS-IBXOBV4 Safety I/O Module and
PLC Program
The safety module must be configured as follows:
Configure the output that is connected to the I/O output cable
assembly for:
• Dual (bipolar mode)
• Safety Pulse Test
Configure the input that is connected to the I/O Input cable assembly
as follows:
• Channel = Single
• Mode = Pulsed Test Input from test output X
• Source = Pulsed output from X
ArmorStart Controller - none required
Safety PLC Program – the program must:
• Force the output contactors to the open state when a safety-
related stop is demanded.
• Force the output contactors to remain in the open state if the SM
feedback is open after a safety-related stop is executed (see Note
1 and Note 2).
Note 1: The program must inhibit the contactor closure to satisfy safety
category 4 of 13849-1.
Note 2: The SM feedback logic should be implemented only after a safety-
related stop for the Bulletin 280/281 controllers. It should be ignored
during normal operation. One of the series contactors is used for the
normal stop/start function for these controllers. Therefore, a
malfunctioning contactor circuit cannot be distinguished from a normal
running state.
Refer to Publication SAFETY-AT018*, for programming examples.
