Digital keypad (KPMS-LE01)
Figure 16-6
The MS300 automatically switches to PLC mode when the external multi-function input terminals
(MI1–MI7) are in PLC Mode selection bit 0 (51) or PLC Mode selection bit1 (52), and the terminal
contact is closed or open. In this case, keypad switching is invalid. The corresponding actions are
listed in Table 16-2.

Using the MS300 digital keypad to implement the PLC functions
 When the PLC screen from the keypad is set to PLC0 (or "Disable" on KPC-CC01), the
built-in PLC is disabled and you cannot use WPLSoft or ISPSoft to connect to it.
 When the PLC screen from the keypad is set to PLC1 (or "PLC Run" on KPC-CC01), the
built-in PLC is enabled and you can use WPLSoft or ISPSoft to connect to it through
Modbus.
 When the PLC screen from the keypad is set to PLC2 (or "PLC Stop" on KPC-CC01), the
built-in PLC is enabled and you can use WPLSoft or ISPSoft to connect to it. However, the
programs in the built-in PLC do not work.
 When the built-in PLC is enabled (PLC1 or PLC2), you can switch between PLC Run or
PLC Stop through WPLSoft or ISPSoft.
 The external terminal control method is the same as shown in Table 16-2 above.
NOTE:

When the input / output terminals (MI1–MI7, Relay, and MO) are included in the PLC program, these
input / output terminals are used only by the PLC. For example, when the PLC program controls Y0
during PLC operation (PLC1 or PLC2), the corresponding output terminal relay (RA / RB / RC)
operates according to the program. At this time, the multifunctional input / output terminal setting has
no effect. Because these terminal functions are already being used by the PLC, you can determine
the DI / DO / AO in use by the PLC by looking at Pr.02-52, 02-53, and 03-30.

When the PLC program uses special register D1040, the corresponding AO contact AFM is occupied.

Pr.03-30 monitors the action state of the PLC function analog output terminals; bit 0 corresponds to
the AFM action state.
Select PLC1 to enter PLC mode setting (see Figure 16-6).
