AH500 Module Manual 11-106 LED status Indication How to deal with E5 The extension rack error or the extension rack does not exist. 1. Check if the extension rack is connected correctly. 2. Check if the extension rack is consistent with the configuration. E6 The data configuration length Check if the configured modules on the rack are exceeds the allowed so many that the configured data length exceeds maximum 500 words the maximum 500 words. E7 AHRTU-DNET-5A is detecting if the node address is duplicate with that of other device on the network. If the code is shown for long, please treat the error by the following means. 1. Ensure that at least two nodes work on the network. 2.
Check if the two ends of the network have been connected with a 121 Ω resistor respectively. 3. Check if the baud rate of the node equipment on the network is the same. 4. Check if the communication cable is abnormal, e.g. loose or cut. 5. Check if the communication cable exceeds the maximum transmission distance. If it does, the system can not be kept stable. 6. Check if the shielded wire has been grounded. 7. Repower AHRTU-DNET-5A. E8 A timeout occurs when Check if AHRTU-DNET-5A and the I/O module are running normally. AHRTU-DNET-5A exchanges data with the I/O module. E9 The number of AH10SCM-5A Reduce the quantity of the AH10SCM-5A module, which should be no more than 8.
module exceeds the maximum. 80 AHRTU-DNET-5A is in STOP state. 1. Turn the switch RUN/STOP to RUN. 2. Check if the control word of AHRTU-DNET-5A is 1. See section 4.1 for details. 83 Downloading the I/O data Wait until downloading the configuration data of configuration in the software AHRTU-DNET-5A is completed. 84 Downloading the data Wait until downloading the serial port configuration data of AH10SCM-5A is completed. configuration of AH10SCM-5A serial port in the software
