Input Autotest: This feature applies to 16- and 32-circuit DC Sink/Source I/O Blocks IC660BBD020, 021, 024, and 025 only. The block can be either in GMR mode or not in GMR mode.

If any input circuits on the blocks in the group should be autotested, select them here. Circuit 16 must have autotest enabled. If no circuits are to be autotested, circuit 16 can have autotest disabled and input devices can be wired directly to the power source instead of being wired to circuit 16.

By default, each circuit is set up for autotesting, as shown by the X next to the circuit number. To turn off autotesting for any circuit, select that circuit (click on the circuit or select it using the cursor keys). Press the space bar key to remove the X. Note: For all unused circuits on the block, autotest should be set to off. Also, it is possible for an input block to include I/O circuits that are not part of the GMR system, and which are not to be autotested. Be sure to turn autotest off for non-GMR circuits.

Output Discrepancy: Specify whether the block should report output discrepancies. This applies to 16- and 32-circuit DC Sink/Source I/O Blocks IC660BBD020, 021, 024, and 025 only. The block must be in GMR mode.

Bus Connect: Select the bus to which the block is connected.

Hot Standby: Specify whether the block should use Hot Standby output redundancy. This feature applies to 16- and 32-circuit DC Sink/Source I/O Blocks IC660BBD020, 021, 024, and 025 only. Operation of Hot Standby mode is described in chapter 3. If the block is not in GMR mode, selecting Hot Standby here tells the system to configure the block to send fault reports to three PLCs.

Block Type: Specify input, output, or mixedI/O. If the block will use the

Input Autotest feature, it must be set up as a mixedI/Oblock.
