Chapter 11 DeviceNet Remote I/O Module AHRTU-DNET The already built group could be added to Sequence by clicking the Add button on the Sequence setting interface. Download the group with sequence as the unit to COM port and make the execution. In addition, besides that the execution group is selected, the group number to be executed when an error occurs can be set at the same time. When the executed group has a fault, execute the group according to the setting of the execution group when the error occurs. 11.4.3 DeviceNet Mapping Data The model of the entire mapping data exchange is shown as below, which is finally mapped to the registers in PLC. Note:
The mapping addresses mentioned below are the D registers in PLC CPU. For AH10DNET-5A master, its input and output starting addresses can be set freely. (The input and output starting addresses are set via HWCONFIG when the DeviceNet Builder software is called through HWCONFIG in ISPSoft; otherwise, the input and output starting addresses are set via the DeviceNet Builder software when the software is used separately.) The lengths of the mapping addresses of the input and output are determined by the configuration of all slaves connected to AH10DNET-5A master. Their maximum lengths are both 495 words.
For AHRTU-DNET-5A, its input and output starting mapping addresses are automatically allocated by the master when AHRTU-DNET-5A is added to the master. And the lengths of the input and output mapping addresses are determined by the configuration of the modules connected to AHRTU-DNET-5A. For the I/O modules, their input and output mapping starting addresses can be allocated automatically or set by users. The lengths of the input and output mapping addresses depend on the configuration of the modules. The ranges of the input and output mapping addresses of the modules are limited by those of the input and output mapping addresses of AHRTU-DNET-5A. 11-49
