Configure Adapter Mode
Introduction
This chapter explains how and why to use the 1756-RIO module in adapter
mode. In adapter mode, the 1756-RIO module can perform two functions
simultaneously.
First, the module can emulate one or more racks of I/O to a scanner,
exchanging data with that scanner (for example, a PLC-5, PLC-3, or SLC
controller). On Active racks, the module writes remote I/O inputs and reads
remote I/O outputs.
Second, it can monitor other remote I/O racks. On Monitored racks, the
1756-RIO module can monitor existing I/O, also known as ‘Monitor mode,’
and can be used to upgrade a PLC-5, PLC-3, or SLC system to a ControlLogix
system. Monitor mode provides existing discrete inputs and outputs, and
Block Transfer reads and writes to the ControlLogix controller.
See
Scan Mode and Monitor Mode on page 99
for a complete description of
using Monitor mode.
The 1756-RIO module communicates with the ControlLogix controller using
up to 10 input connections and 10 output connections via produced/
consumed data. Remote I/O data maps into the connections by the
configuration tool.
In this chapter, you use the configuration tool to configure the module in
adapter mode to prepare it for use on the Remote I/O network. You will:
• configure the racks automatically or manually.
• add and configure block transfer modules.
• map the remote I/O modules to the ControlLogix controller produced/
consumed data.
