DeviceNet Slave Communication Module IFD9502 4 LED Indicators & Trouble-shooting There are 3 LED indicators on IFD9502, Network Status LED, Module Status LED and Scan Port LED, for displaying the connection status of the communication. 4.1 Network Status LED 4.2 Module Status LED 4.3 Scan Port LED DVP-PLC Application Manual 26 Code Baud rate 1 19,200 bps 2 38,400 bps 3 57,600 bps 4 115,200 bps LED status Indication How to deal with it? Off No power; Duplicating ID has not completed 1. Check the power of IFD9502 and see if the connection is normal. 2. Check if the node communication on the BUS is normal. 3. Make sure at least 1 node is normally communicating with the network through IFD9502.
Green light flashes Online, but not connected to DeviceNet -- Green light on Online, and connected to DeviceNet normally -- Red light flashes Online, but I/O connection time-out occurs. -- Red light on Network failure. Failed ID duplication or Bus-off. 1. Make sure all node addresses on the BUS are not repeated. 2. Check if the network installation is normal. 3. Check if the baud rate of IFD9502 is consistent with that of the BUS. 4. Check if the station No. of IFD9502 is valid. 5. Check if your choice of switch on IFD9502 is consistent with the actual connected equipment. 6. Check if IFD9502 is correctly wired with the equipment. LED status Indication How to deal with it?
Off No power; off-line Check the power of IFD9502 and see if the connection is normal. Green light flashes Waiting for I/O data, no I/O data or PLC program is being edited. IFD9502 has passed operation test and is waiting for I/O data Green light on I/O operation in progress normally. -- Red light flashes Configuration problem; IFD9502 is not connected to equipment 1. Reset parameters in IFD9502. 2. Check if IFD9502 is correctly wired with the equipment. Red light on EEPROM is damaged, or other hardware error. Send back to factory for repair. LED status Indication How to deal with it? Off No power Check the power of IFD9502 and see if the connection is normal.
