 When the external multifunctional input terminals (MI1 to MI7) are in PLC Mode select bit 0
(51) or PLC Mode select bit 1 (52), and the terminal contact is closed or open, it will
compulsorily switch to the PLC mode, and keypad switching will be ineffective.
Corresponding actions are as follows:
PLC mode
PLC Mode select bit 1 (52) PLC Mode select bit 0 (51)
Using KPC-CC01 MS300

Use of MS300 digital keypad to implement PLC functions
 When the PLC screen switches to the PLC1 screen, this will trigger one PLC action,
and the PLC program start/stop can be controlled by communications via the WPL.
 When the PLC screen switches to the PLC2 screen, this will trigger one PLC stop, and
the PLC program start/stop can be controlled by communications via the WPL.
 The external terminal control method is the same as shown in the table above.
NOTE

When input/output terminals (MI1 to MI7) are included in the PLC program, these input/output
terminals will only be used by the PLC. As an example, when the PLC program controls Y0 during
PLC operation (PLC1 or PLC2), the corresponding output terminal relay (RA / RB / RC) will operate
in accordance with the program. At this time, the multifunctional input/output terminal setting will be
ineffective. Because these terminal functions are already being used by the PLC, the DI / DO / AO in
use by the PLC can be determined by looking at Pr. 02-52, 02-53, and 03-30.

When the PLC's procedures use special register D1040, the corresponding AO contact AFM1 will be
occupied,

Pr. 03-30 monitors the state of action of the PLC function analog output terminal; bit 0 corresponds to
the AFM1 action state.
