(SYMPTOMS)

POSSIBLE AREAS OF MISADJUSTMENT(S)

RECOMMENDED

COURSE OF ACTION

		1.	Current Interference	1.	Verify that cables are not run
					along current carrying conductors.
					This would include the welding
					cables.

		2.	Termination	2.	Verify that the DeviceNet bus is
					terminated correctly.

		3.	Shield	3.	Verify that the cable shielding is
					correctly grounded at the bus
Device goes off line during welding					power supply. The shield should
					be tied into the bus ground at only
					one point.

		4.	Power Supply	4.	Verify that the power supply can
					supply more than enough current
					for the devices in the network.

		5.	Expected Packet Rate	5.	Verify that 1000/(Expected Packet
					Rate) ≤ (scans per seconds). The
					Monitor section of the Observer
					application displays these values.
