I - 4 Diagnostics
General Information
When the CSS I/O box is connected to the DRO, the DIAGNOSTICS
menu under INSTALLATION SETUP provides further diagnostic
possibilities. The information available varies depending on the
configuration of the system, Switching I/O, CSS, or Mill Spindle
functions.
Switching I/O functions
The SWITCHING I/O DIAGNOSTICS shows the status of the
communication via the CAN bus and the state of the switching inputs
and outputs to provide monitoring of the switching functions.
The CAN STATUS field shows the state of the bus communication
between the DRO and the CSS I/O.
The status information has the following meaning:
The SWITCHING I/O field shows the state of the inputs and the switch
position of the relays.
All currently active inputs (1 to 3) are shown in the ON field.
All currently active relay outputs (1 to 9) are shown in the OFF field.
The CALIBRATE soft key is used to re-synchronize the communication
with the CSS I/O. This, however, is only required if the module is not
detected upon power on.
