Chapter 11 DeviceNet Remote I/O Module AHRTU-DNET 11.4 Configuration of AHRTU-DNET-5A As the DeviceNet slave, AHRTU-DNET-5A is used to achieve the remote data exchange between the DeviceNet master and the AH500 series I/O modules connected to itself. Transmits the output data of the DeviceNet master to I/O modules. Transmits the input data of I/O module to the DeviceNet master. 11.4.1 Terms 11-17 Product picture Type Function TAP-CN01 The CAN bus topology tapping box with the 120 ohm resistor enclosed which is controlled to be effective or not via its switch.
TAP-CN02 The CAN bus topology tapping box with the 120 ohm resistor enclosed which can be controlled to be effective or not via its switch. TAP-CB01 TAP-CB01: DeviceNet trunk cable TAP-CB02 TAP-CB02: DeviceNet drop cable No . Name Unit Explanation 1 AHRTU-DNET-5A input data range Word The input data mapping range of all modules connected to AHRTU-DNET-5A. The range depends on the input starting address and offset which the master assigned to AHRTU-DNET-5A. The max. offset is 126 as DVPDNET-SL works as the master; the max. offset is 489 as AH10DNET-5A is the master. 2 AHRTU-DNET-5A output data range Word The output data mapping range of all modules connected to AHRTU-DNET-5A.
The range depends on the output starting address and offset which the master assigned to AHRTU-DNET-5A. The max. offset is 126 as DVPDNET-SL works as the master; the max. offset is 489 as AH10DNET-5A is the master. 3 Control word Word The first word of the output data which the master assigned to AHRTU-DNET-5A is the control word of AHRTU-DNET-5A. It is used for setting the work mode of AHRTU-DNET-5A. When the control word content is set to 2, AHRTU-DNET-5A is in STOP mode; when the control word content is set to 1, AHRTU-DNET-5A is in RUN mode.
