Use a fieldbus cable to connect the DeviceNet
TM
fieldbus node to the
DeviceNet

fieldbus card in your PC.
24V power is supplied to the fieldbus via connections V+, V- of the 5-pin
fieldbus connector (Series 231
(MCS)
) from an external fieldbus power supply
unit.

Turn the operating voltage on.
4.
Turn on your PC.
After the power is switched on, the fieldbus controller is initialized. The fieldbus
controller determines the I/O module configuration and creates a process image.
During startup, the I/O LED (red) will flash. After a brief period, the I/O LED
lights up green, indicating that the fieldbus controller is operational.
If an error occurs during start-up indicated by the I/O LED flashing red, evaluate
the error code and argument and resolve the error.
