1. The following data cannot be overwritten when pin 1 is ON:
• All parts of the user program (programs in all tasks)
• All data in the parameter area (such as the PLC Setup and I/O tables)
When pin 1 is ON, the user program and parameter area will not be cleared
when the memory clear operation is performed from the CX-Programmer.
2. The Controller Section will not enter any mode except PROGRAM mode
after backing up data to a Memory Card using the easy backup operation.
To enter RUN or MONITOR mode, turn OFF the power supply, turn OFF
pin 7, and then restart the NSJ Controller. This will enable changing the op-
erating mode as normal.
A Memory Card can be used to back up all Controller Section data, including
the user program, parameters, I/O memory, and comment memory files. Auto-
matically transferring data from the Memory Card at startup can also be used
to enable batteryless operation.
Press the power supply switch to disconnect power before removing the Mem-
ory Card. Also, press the Memory Card Power Supply Switch to perform an
easy backup operation.
Serial port C has the same functionality as the RS-232C port on a CJ1-H CPU
Unit with unit version 3.0. The following serial communications modes are
supported: Toolbus, Host Link, NT Link, No-protocol, and Serial Gateway.
An Expansion Unit can be mounted here.
Usage
Turn ON to use the RS-232C port for the CX-
Programmer in Toolbus mode.
Set pin 6 to ON or OFF and use A39512 in
