Using singleslot modules: Using doubleslot modules:

2Slot

• The right slot of the primary I/O group can be

another singleslot block transfer module, or an

8point input or output module.

• The left slot of the complementary I/O group must be

empty.

• In the right slot of the complementary I/O group, you

can place an 8point output module; this slot must be

empty if the corresponding slot in the primary I/O

group is a singleslot block transfer module.

• The left slot of the complementary I/O group must be

empty.

• In the right slot of the complementary I/O group, you

can only place an 8point output module (if any).

1Slot Leave the corresponding I/O group in the

complementary chassis empty.

• The left slot of the two corresponding I/O slots in the

complementary chassis must be empty.

• In the right slot of the two corresponding I/O slots in

the complementary chassis, you can place an input,

output, or singleslot block transfer module (if any);

the modules can be either 8point or 16point I/O

modules.
