C h a p t e r 1 2 Tr o u b l e s h o o t i n g1 2 - 2 712_Code Explanation CorrectionE2The slave device in the scan listdoes not exist or is offline whenAS01DNET-A is in master mode.1. Check if there is a change in the node address of the slave.2. Check if the communication cable is disconnected or connectedloosely.3. Check if the bus cable length exceeds the maximum transmissiondistance. If so, the system may not be stable.The I/O connection between theslave AS01DNET-A and themaster is broken whenAS01DNET-A is in slave mode.E3 AS01DNET-A fails to transmitdata.1. Make sure that the connection between AS01DNET-A and thenetwork is normal.2. Check if the baud rate of AS01DNET-A is the same as that ofother node in the network.E4Error detected in sequence offragmented I/O data from theslave device.Check if the slave is operating normally.E5The slave device returns errorwhen AS01DNET-A attempts tocommunicate with it.Check if the slave is operating normally.E6IO data size returned from theslave is bigger than thatconfigured in Scan List.Check that the IO data size of the slave should be the same as thatconfigured in Scan List.E7 AS01DNET-A is checking MACID.If the code is displayed long, do the troubleshooting according to thefollowing steps.1. Make sure that at least two nodes work normally in the network.2. Check if either end of the network is connected with the terminalresistor of 121Ω.3. Check if the baud rates of the node devices in the network aresame.4. Check if the communication cable is normal so as to avoid thatthe cable is disconnected or connected loosely.5. Check if the bus cable length exceeds the maximumtransmission distance. If so, the system may not be stable.6. Check if the shielded wire of the network cable is grounded.7. Re-power AS01DNET-A scanner module.12.4.7 Error Codes and LED Indicators for Module AS01DNET (RTUMode)Code Indication How to deal with0~63 Node ID of the scanner module(When in RUN state) No correction neededF0 The node ID is repeated orexceeds allowed range.1. Ensure that the node ID of AS01DNET (RTU) is unique inthe DeviceNet network within the range of 0~63.2. Repower it on after changing the node ID.F1No I/O module is configured toAS01DNET (RTU) in theDeviceNet Builder software.Add I/O modules in AS01DNET (RTU) in the DeviceNetBuilder software and download the configuration data toAS01DNET (RTU) after the configuration is finished.F2 The work voltage of AS01DNET(RTU) is too low.Check if the power supply for AS01DNET (RTU) worksnormally.F3 AS01DNET (RTU) enters thetest mode. Repower AS01DNET (RTU).
