2.7 Resetting the Master CPU error
If targets become unresponsive, check for the presence of the CPU error.
If error, check if any Ethernet cables have been disconnected. You will need to clear the
error. See the square error LED on red on the R04ENCPU module (picture below).
To remove the error, power off the Master Control Panel by resetting the fuse. Wait till all
the lights have gone out then switch the panel ON again.
If the error is still on the CPU you will have to reset the CPU. To do this pull the tab marked
"Pull" on the CPU module. This will lift the smoked cover up.
Beneath the cover is a 3 position switch. The switch moves horizontally and should be over
to the right.
Move the switch all the way to the left and hold it till the lights on the CPU go out.
Release the switch and it will move to the center position. When the CPU has been reset
the lights will come back on. Move the switch from the center position all the way to the
right. The switch will stay in this position. The "error" light on the CPU should now be out.
The error light on the CC-Link module will still be on. The "error" light on the CC-Link
module is normal. The system has been designed to control up to 40 lanes. Because the
network cannot see all 40 lanes it will throw up an error. This error is ignored by the CPU.
