Example: IOREF
The following example demonstrates a program to transfer the input I0 status to output Q0 using the IOREF instruction.
Input I2 is designated as an interrupt input. For the interrupt input function, see page 5-20.
M8120 is the initialize pulse special internal relay.
D8032 stores 0 to designate jump destination label 0 for interrupt input
I2.
When input I2 is on, program execution jumps to label 0.
M8125 is the in-operation output special internal relay.
IOREF immediately reads input I0 status to internal relay M300.
M300 turns on or off the output Q0 internal memor y.
Another IOREF immediately writes the output Q0 internal memor y status
to actual output Q0.
Program execution returns to the main program.
