9/Series Adapter Modules for
1771 and 1746 I/O Devices
10B-5
Use the 1746 I/O Ring Adapter Module to interface Allen-Bradley 1746
I/O devices with your 9/Series control. The 1746 I/O ring adapter module
provides the system installer with the option of using 1746 I/O devices in
the 9/Series fiber--optic I/O ring.
The adapter module must be placed in the first slot (slot 0) of the 1746
series B I/O chassis. The 1746 I/O ring adapter module provides the
interface between the 1746 I/O chassis and the fiber-optic I/O ring of the
control using the fiber--optic connectors on the adapter module.
Figure 10B.3
1746I I/O Ring Adapter
You can place several 1746I modules with 1746 I/O chassis in the 9/Series
fiber-optic ring. Each 1746 I/O chassis must contain its own 1746I module
(daisy chaining racks together using one 1746I module is not allowed).
The number of I/O points/chassis is limited to the number of ASRN chips
supported by the 9/Series fiber--optic ring. Use page 10B-10 to calculate
how many ASRN chips are required for each I/O chassis. A maximum of
16 chassis are allowed on the 9/Series fiber-optic I/O ring.
To install the 1746I module in the 9/Series I/O ring you must first assign
the module an address on the 9/Series I/O ring. If the module is already
installed in your 1746 I/O chassis, you must remove the module to set the
module address. Remove the module by pressing in on the locking tabs on
the top and bottom of the 1746I module and sliding the module out of the
chassis.
