System Assembly
The module can be attached to the controller or an adjacent I/O module before or
after mounting. For mounting instructions, see “Panel Mounting” on page 5, or
“DIN Rail Mounting” on page 6. To work with a system that is already mounted,
see “Replacing a Single Module within a System” on page 7.
The following procedure shows you how to assemble the Compact I/O system.
1. Disconnect power.
2. Check that the bus lever of the module to be installed is in the unlocked
(fully right) position.
3. Use the upper and lower tongue-and-groove slots (1) to secure the modules
together (or to a controller).
4. Move the module back along the tongue-and-groove slots until the bus
connectors (2) line up with each other.
5. Push the bus lever back slightly to clear the positioning tab (3). Use your
fingers or a small screw driver.
6. To allow communication between the controller and module, move the bus
lever fully to the left (4) until it clicks. Ensure it is locked firmly in place.
7. Attach an end cap terminator (5) to the last module in the system by using
the tongue-and-groove slots as before.
8. Lock the end cap bus terminator (6).
IMPORTANT: A 1769-ECR or 1769-ECL right or left end cap must be used to
terminate the end of the serial communication bus.
!
ATTENTION: When attaching I/O modules, it is very
important that the bus connectors are securely locked
together to ensure proper electrical connection.
