Module Switch Assemblies
You must set two switch assemblies to configure your adapter
module. Figure 1.2 shows the location of the switches.

Switch Locations
Switch Assembly
(S1)
Switch Assembly
(S2)
The S1 Assembly is used to select:
•
the I/O rack number
•
the first I/O group number
•
I/O scanner communication with or without complementary
I/O (for PLC-2 family processors)
The S2 Switch Assembly selects:
•
a specific baud rate based on the maximum I/O chassis
distance
•
I/O scanner communication with or without complementary
I/O (for PLC-2 family processors)
•
scan - processor will scan all slots in the chassis, or all but the
last four slots in the chassis
•
link response - establishes series B emulation response time
required for compatibility with PLC-2 and PLC-3 scanners.
Field Wiring Arm
The field wiring arm (cat. no. 1771-WB) provides connection points
for:
•
I/O communication cables
•
a user-supplied I/O chassis restart pushbutton
The field wiring arm (Figure 1.1) pivots on the front of the chassis to
connect with the module’s printed circuit board. This feature allows
you to remove the adapter module without disconnecting the system
wiring.
