Status Indicators
The status indicator LEDs on the CPU front panels have specific functions which can help in
programming and troubleshooting.
Mode Switch Functions
The mode switch on the DL06 PLC provides positions for enabling and disabling program
changes in the CPU. Unless the mode switch is in the TERM position, RUN and STOP mode
changes will not be allowed by any interface device, (handheld programmer, DirectSOFT
programming package or operator interface). Programs may be viewed or monitored but no
changes may be made. If the switch is in the TERM position and no program password is in
effect, all operating modes as well as program access will be allowed through the connected
programming or monitoring device.
