2-3-2 Identifying and Resetting Errors with an NS-series PT
You can connect one of the following OMRON NS-series PTs to an NJ-series CPU Unit through an Eth-
erNet/IP network, and use it to read and reset errors that occurred in the Controller. (The Trouble-
shooter of the PT is used.)
To perform troubleshooting from an NS-series PT, connect the PT to the built-in EtherNet/IP port on the
CPU Unit.
• NS8, NS10, NS12, and NS15
NS@-T@01-V2 (The V2 versions have an Ethernet port.)
• NS5
NS5-@Q11-V2 (These models have expanded memory and an Ethernet port.)
• NSJ8, NSJ10, and NSJ12
All models
• NSJ5
NSJ5-@Q11-@ (These models have expanded memory and an Ethernet port.)
The above models of NS-series PTs with system version 8.5 or higher are compatible with the NJ-
series Controllers.
You can check for errors in the Controller using the Troubleshooter of an NS-series PT that is compati-
ble with NJ-series Controllers. You can also use the Troubleshooter to read detailed error information
and corrections for current errors. However, for some NX Units, you cannot check the event name,
event code, details, and attached information for current errors.
Refer to the NS-series Programmable Terminals Programming Manual (Cat. No. V073) for details on
the NS-series PT’s Troubleshooter.
The following example demonstrates the procedure used to check for errors with an NS8, NS10, NS12,
or NS15 PT.
You can check the event source in the Function Module View of the Troubleshooter. If you click the
Select Button for a function module in the Event source Table, you can display the Source details for
events for that function module. You can select the list in the Source details Table to display the List
View.
The List View displays a list of the errors produced by the event source that you selected in the Function
Module View.
