I have a problem with the above NC control. The four LED's on the
operators panel are flashing together at about 4hz and there is no
crt display. The control was alright but the screen froze and the
LED's started flashing. I fitted another COM-CPU board but I cannot
get the NC to run. The PLC is running alright. Can anyone help please.
