AH500 Module Manual 11.4.2 Introduction of Software Please make sure to have installed the communication manager COMMGR when using DeviceNet Builder of new version to connect with PLC CPU. (Please refer to appendix C for more details on COMMGR usage) 11-18 No . Name Unit Explanation 4 Status word Word The first word of the input data which the master assigned to AHRTU-DNET-5A is the status word of AHRTU-DNET-5A. It is used for displaying the operational state of AHRTU-DNET-5A. Refer to section 4.3.3 for more details on status word. 5 Module input data range Word The range value is determined by the input starting address and input mapping parameter length of each module.
The input mapping parameter length of each module is composed by both of the default mapping parameter length of the module and user-added mapping parameter length (max. 20 words). The digital I/O module length is fixed and so user could not add the parameter. 6 Module output data range Word The range value is determined by the output starting address and output mapping parameter length of each module. The output mapping parameter length of each module is composed by both of the default mapping parameter length of the module and user-added mapping parameter length (max. 20 words). The digital I/O module length is fixed and so user could not add the parameter.
7 Input data length Word The sum of status word length of AHRTU-DNET-5A and the input data length of the connected modules. The status word length is 1 word, it is 1 word per 16 points for the digital input module and the input data lengths of analog I/O module, temperature module and AH10SCM-5A are determined by the default mapping parameter length and user-added parameter length. 8 Output data length Word The sum of control word length of AHRTU-DNET-5A and the output data length of the connected modules.
The control word length is 1 word, it is 1 word per 16 points for the digital output module and the output data lengths of analog I/O module, temperature module and AH10SCM-5A are determined by the default mapping parameter length and user-added parameter length. 9 When loses -- When AHRTU-DNET-5A is disconnected from the DeviceNet DeviceNet network, how AHRTU-DNET-5A will deal with the trouble. User connection can choose “RTU keep running” or “RTU stop running”. 10 When I/O module error occurs -- When AHRTU-DNET-5A detects that any one of the connected I/O module alerts the errors such as alarming, power-off, how AHRTU-DNET-5A will deal with the trouble.
User can choose “RTU keep running” or “RTU stop running”. 11 Auto-Addr -- Auto-assign the mapping address and the offset of the mapping parameters of all modules according to the module sequence. For the analog module, only the default parameters are assigned if user does not choose the mapping parameters. 12 Clear address -- Clear the assigned mapping address of all modules.
