Troubleshooting
DeviceNet
Applicable for the DIN-rail (with diagnostics) only
Vendor ID code = 0459
Diagnostics Display
“OK U”
Devicenet unconnected (may be unplugged from
network)
“OK C”
Devicenet connected but not allocated (passed
duplicated mac id check)
“OK A”
Devicenet allocated (in service)
“OK F”
Devicenet faulted out (mat controller will work, but
not devicenet)
User adjustable MAC_ID
(default = 63)
If the NSD controller fi nds a duplicate MAC_ID,
it will go off-line and display the current MAC_ID
on the diagnostics display. Use the Fault Reset
button to decrement the MAC_ID to a new (unused)
value. Hold the button in for 2 sec to program it
permanently.
The NSD controller will now check for duplicate
MAC_ID’s using the new ID.
Network adjustable BAUD_RATE
(default = 125Kb/s)
If your network runs at different baud rate, you can
adjust the NSD controller using standard DeviceNet
set commands. The NSD controller supports 125,
250, and 500Kb/s rates. After you change the Baud
rate, you must cycle power to NSD to re-enable
Devicenet.
Network settable CONNECTION
(default= offl ine)
The NSD controller will allow EXPLICIT and BIT_
STROBE connections only
Network adjustable EPR_RATE timer
(default= 10sec for explicit connection, none for
bit-strobe)
The EPR (Extendend packet rate) timer is set in
250msec increments. A value of less than 250 will
keep the connection forever.
