I/O Module Hot Swap
The following steps explain how to “Hot Swap” an I/O module.
1. Remove I/O module from base. (If necessary, refer to the Terminator I/O
Installation & I/O Manual for steps on removing an I/O module).
2. The T1K–MODBUS DIAG LED will turn ON.
3. Install a new I/O module with the exactly the same part number.
4. Verify that the T1K–MODBUS Base Controller LEDs have returned to normal.
A feature that may be used in a non–continuous process application is the Outputs
Enable/Disable switch. The switch is located on the front of the T1K–MODBUS base
controller. This feature may be used at a convenient time during the process
application to replace an I/O module.
When the switch is in the Disable position:
S
all outputs are Disabled (OFF)
S
the Base Controller’s output status memory is cleared
S
the Base Controller ignores any outputs command from the Master Module
