Brief instructions on commissioning
2.1 Commissioning on PROFIBUS DP
ET 200M
32 Operating Instructions, 04/2022, EWA-4NEB7806006-09
SM 322: Short-circuit to L+
1. Open the front panel of the DO-module and use a wire to short circuit the digital output 0
(terminal 3) after L+ (terminal 1).
2. Note the status LEDs.
IM 153-2:
– SF: ON
SM 322; DO 8 x DC 24 V/0,5 A:
– SF: lights up → a diagnostic message is pending
– F0: light up → channel error
– 0: OFF → Output is not active
3. Evaluate the diagnostic message.
Result:
– Station status 1 Byte x.3 is set → external diagnostics
– Identifier-related diagnostics: Byte (x+7).4 is set → Slot 5
– Channel-related diagnostics:
Byte (x+16).0 to (x+16).5: 000100
B → Slot 5
Byte (x+17).0 to (x+17).5: 000000
B → Channel 0
Byte (x+18).0 to (x+18).4: 00001
B → Short circuit
4. Remove the wire between terminal 3 and terminal 1.
Evaluate the diagnosis LEDs once again.
IM 153-2:
– SF: off
SM 322; DO 8 x DC 24 V/0,5 A:
– SF: off
– F0: off
– 0: On
The diagnostic message is deleted.
