Replace a Single Module Within a System
The module can be replaced while the system is mounted to a panel or DIN rail.
1. Remove power.
Refer to Remove Power on page 3.
2. Remove the upper and lower mounting screws from the module or open the
DIN latches using a flat-blade or Phillips screwdriver.
3. Move the bus lever to the right to disconnect or unlock the bus.
4. On the right-side adjacent module, move its bus lever to the right (unlock)
to disconnect it from the module to be removed.
5. Gently slide the disconnected module forward.
If you feel excessive resistance, check that the module is disconnected from
the bus and that both mounting screws are removed or DIN latches opened.
6. Be sure that the bus lever on the module and on the right-side adjacent
module are in the unlocked (fully right) position before installing the
replacement module.
7. Slide the replacement module into the open slot.
8. Connect the modules by locking (fully left) the bus levers on the
replacement module and the right-side adjacent module.
9. Replace the mounting screws or snap the module onto the DIN rail.
IMPORTANT
You must use a 1769-ECR or 1769-ECL right or left end cap to terminate the end
of the serial communication bus. An I/O configuration fault will occur if an end
cap is not used.
TIP
It may be necessary to rock the module slightly from front to back to remove it,
or, in a panel-mounted system, to loosen the screws of adjacent modules.
