Chapter 11 DeviceNet Remote I/O Module AHRTU-DNET When multiple errors exist simultaneously, the digital displayer of AHRTU-DNET-5A will show the error codes cyclically. For example, E4 12 E5 02 E4 12 E5 02 is shown in cycle, the error indication is as follows. E4 indicates that the module error occurs or the module is offline. See the error code for details. 12 indicates that the position of the module where the error exists. The first number 1 indicates the module is positioned on the first rack, the second number 2 indicates that the module is connected to the slot 2 on the rack. (Rack number:1~8; 1 refers to the main rack; 2~8 are the extension rack; the slot number:
0~11) E5 indicates that the extension rack error or the offline problem occurs. See error code for details. 02 indicates that the rack which has a fault or is offline is the second rack (Rack number is 1~8; 1 refers to the main rack; 2~8 are the extension rack). 11.7.3 Status Word Diagnosis The status word in AHRTU-DNET-5A is used to display the running state of the special module, DI/DO module and the Modbus equipment. See the following table on the diagnosis of the status word. 11-107 Bit Status value Indication How to deal with Bit 0 0 AHRTU-DNET-5A is in RUN -- state. 1 AHRTU-DNET-5A is in stop Restart AHRTU-DNET-5A. state.
