Safety I/O Module Features Chapter 5
Use Test Output with a Safety Input
A test output can be used in combination with a safety input for short circuit and
cross-channel fault detection.
Configure the test output as a pulse test source and associate it to a specific safety
input. The associated safety input must use a Point Mode = Safety Pulse Test.
These mappings are the only allowed and default digital-input-to-test-output
association mappings for Safety Pulse Test configuration. Only a test output that
is configured as Pulse Test can be used as test source.
Figure 7 - FLEX 5000 I/O Safety Input Module - Input Connected to Test Output
This diagram shows:
• A 2-wire sensor is connected to safety input 0, with test output 0
configured as Test Pulse/Power Supply.
• A 3-wire sensor is connected to safety input 15, with test output 7
configured as Power Supply.
