Diode

Power feed outputs require isolation diode when single input device is wired to more than one block.

Operation of the Input Autotest

The following actions are performed during the Input Autotest:

Hthe power feed outputs * are pulsed Off. Selected input channels are pulsed On.

Hall associated inputs are checked for their ability to detect the On or Off state, as appropriate, and a fault is reported if the correct state is not detected..

While it is being tested, a block continues to supply its last valid set of inputs instead of the physical inputs to the PLCs.

Test Verification

By allowing some inputs to be turned On, the Input Autotest checks its own operation. The following table shows cycles in which blocks are autotested, and circuits that are turned On in the same cycle

Notes: Bit 16 corresponds to the power feed output. It is always 0.

For 16-Circuit blocks, each circuit is turned On each cycle when looked at across all 3 blocks, but the same circuit is never turned On at more than one block at a time.

For 32 Circuit blocks, almost all circuits are turned On each cycle when looked at across all 3 blocks, but the same circuit is never turned On at more than one block at a time.

*also see chapter 8 for installation and wiring information.
