3–10 Addressing Modes for Your Remote I/O

Follow these guidelines when configuring your remote system with

complementary I/O chassis:

• Assign the complementary I/O rack number to a chassis of equal

or smaller size than the primary chassis.

• If the complementary chassis is smaller than the primary one, set

the last chassis switch on the complementary chassis to the ON

position, unless the adapter is in the faulted I/O search mode.

• For PLC-2 family processors:

• Connect the complementary chassis to the same scanner

channel as the primary chassis.

• Connect the complementary chassis to the remote trunkline as

though they were additional primary chassis.

• For PLC-3 processors, connect the complementary chassis to a

different scanner channel as the primary chassis.

• Assign the same beginning I/O group number to both I/O racks.

• You cannot configure complementary I/O in a chassis that uses a

combination of 2-slot addressing and 16-point I/O.

• You cannot use 32-point I/O modules in a complementary I/O

configuration when you select 2-slot or 1-slot addressing.

• You can place an output module opposite another output

module; they reflect the same bits in the output image table.

• Do not place an input module opposite an input module.

You can use the following modules in either primary or

complementary I/O chassis opposite any type of module:
