Refer to the module LED to detect a pulled interlink cable, an inoperable module, or reset module (LED on, off, or flashing to display status or detected error pattern). Refer to your application to detect the module status (link Ethernet port, EIP scanner status, DDT, system words). Use the DTM browser in Control Expert to detect whether a 140NOC78•00 module is inoperable or has been reset. Not applicable. Use the FactoryCast rack viewer to detect if a 140CRP31200 module or 140NOC78•00.module is inoperable or has been reset. Use ConneXium Network Manager, HiVision, or other Ethernet network management tool to detect if a 140CRP31200 module or 140NOC78•00.module is inoperable or has been reset.

Refer to the module LED to detect a pulled cable or a powered-off device (LED on, off, or flashing to display status or detected error pattern). Refer to your application (via system word, 140CRP31200 DDT, or MSTR blocks) to detect a pulled cable, a powered-off device, a break in the main ring or sub-ring, or slow network traffic. Not applicable. Use the DRS web pages to detect a pulled cable or a break in the main ring. Use the FactoryCast rack viewer to detect if a 140CRP31200 module is inoperable or has been reset. Use ConneXium Network Manager, HiVision, or other Ethernet network management tool to detect a pulled cable in a 140CRP31200 module, a •••CRA312•0 module, or a DRS. Also use this tool to detect DRS power state and slow distributed I/O traffic. NOTE: Rack Viewer does not support •••CRA312•0 modules.
