Special data register for forced I/O | LG Electronics 120S specs

Chapter 5 Power Supply / CPU

2) Special data register for forced I/O

The contents of forced I/O setting is registered to special data register as below.

It is possible to use ‘forced I/O function’ to program.

Items	Special Device
All Forced I/O enable	M1910
Forced I/O enable by bit	D4700 ~ D4763
Forced I/O set data	D4800 ~ D4863

3)Force on/ off Processing timing and method

(1)Forced Input

After data have been read from input modules, at the time of input refresh the data of the junctions which have been set to force on/off will be replaced with force setting data to change the input image area. And then, the user program will be executed with real input data and force setting data.

(2) Forced output
When a user program has finished its execution	the output image area has the operation results. At	the time
of output refresh the data of the junctions which	have been set to force on/off will be replaced with	force se

tting data and the replaced data will be output. However, the force on/off setting does not change the output image area data while it changes the input image area data.

(3) Precautions
y Turning the		power off and on, changes of the operation mode or operation	by reset switch does not change
the	previous force on/off setting data. They remain within the CPU module		and operation is executed with
the	same	data.
y Forced I/O		data will not be cleared even in the STOP mode.

yWhen setting new data, disable every I/O settings using the setting data clear function and set the new data.
