 When the external multifunctional input terminals (MI1 to MI8) are in PLC Mode select bit0
(51) or PLC Mode select bit1 (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:
Using KPC-CC01 Using KPC-CE01
Disable
PLC Run
PLC Stop

Use of KPC-CE01 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 (FWD REV MI1 to MI8 MI10 to 15, Relay1, Relay2 RY10 to RY15, MO1 to MO2
MO10 to MO11,) 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 parameter 02-52, 02-53, and 03-30.

When the PLC's procedures use special register D1040, the corresponding AO contact AFM1 will be occupied,
and AFM2 corresponding to special register D1045 will have the same situation.

Parameter 03-30 monitors the state of action of the PLC function analog output terminal; Bit0 corresponds to the
AFM1 action state, and Bit1 corresponds to the AFM2 action state.
 PLC functions are as shown in the figure on the left; select
item 2 and implement PLC functions.
1: No function (Disable)
2: Enable PLC (PLC Run)
3: Stop PLC functions (PLC Stop)
