"CCU DL TIMEOUT"

[Ruthain]

Hi there,
I have this problem with my CNC machine controller which still running on DOS.
It now gives me this message at the boot-up saying: CCU DL timeout!! Error loadsing CCU firmware into C:\P6M."
Basically, the P6M is a Directory in my HDD where the CCU software or the Controller Software get stored.

Can someone perhaps know what this error message means and how to go about solving it? Thank you in advance

Ruthain.
