Processing of external input (X)
Regardless of the state of the input from the input device, forced on/off operation will
take precedence at a contact specified for forced input/output. At this time, the input
LED will not blink, however, the area of input X in the operation memory will be rewritten.
Contacts not specified will read in the on/off state according to the condition of the input
from the input device.
Processing of external output (Y)
Regardless of the result of operation, forced on/off will take precedence at a contact
specified for forced input/output. At this time, the area of output Y in the operation
memory will be forcedly rewritten. External output will take place according to the
input/output update timing in the above diagram.
The on/off state of contacts not specified will be determined by the operation result.
Timer (T) and Counter (C)
Regardless of the timer/counter input condition, forced on/off operation will take
precedence at a contact specified for forced input/output. At this time, the contact of the
timer (T) or counter (C) in the operation memory will be rewritten. Timing and counting
will not take place during control.
The on/off state of contacts not specified will be determined by the operation result.
