AC500-eCo - 11 - Hardware Introduction
2.1.6 Mode Selection Switch RUN/STOP
AC500 CPUs PM554 and PM564 have RUN/STOP mode selection switch. User application
programs can only be implemented when RUN/STOP switch is set to RUN mode. If RUN/STOP
switch is set to STOP mode, the user application programs will be stopped.
It must be use the screwdriver to change swatch’s condition. False tools can create CPU’s
damage.
2.1.7 Status Display on the AC500 CPU
Figure 4 Status LEDs of AC500 CPU PM564
Status of the LEDs for CPU module
On the AC500 CPUs PM554 and PM564 modules, 3 LEDs on the upper left side indicate the
module operation status and 16 LEDs indicate the status of Input/Output signals.
LED Status Color LED = ON LED = OFF
PWR 24 V DC or 100~240V AC
power supply is provided
Red voltage is present voltage is missing
RUN activity status green CPU is in RUN mode CPU is in STOP mode
ERR error indication red An error has occurred. No errors are encountered
or only warnings.
Status of the LEDs for onboard I/Os
The statuses of the onboard inputs/outputs are indicated by yellow LEDs (one per channel).
There is no difference among the channels.
Module LED Status Color LED = OFF LED = ON
Inputs I0…I7 Digital Input Yellow Input = OFF Input = ON
