Function
Meaning
Usage
Used to prevent programs from being acci-
dently overwritten from Programming
Devices (the CX-Programmer).
Used to store the programs in the Memory
Card to switch operations, or to automatically
transfer programs at startup (Memory Card
ROM operation).
Note When pin 7 is ON and pin 8 is OFF,
easy backup reading from the Memory
Card is given priority, so even if pin 2 is
ON, the user program will not be auto-
matically transferred from the Memory
Card when power is turned ON.
