Ch a pt er 11 DeviceNet Re m ote I/O Module AHRTU-DNET11-49The already built group could be added to Sequence by clicking the Add button on theSequence setting interface. Download the group with sequence as the unit to COM port andmake the execution.In addition, besides that the execution group is selected, the group number to be executedwhen 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 DataThe model of the entire mapping data exchange is shown as below, which is finally mapped to theregisters 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 andoutput starting addresses are set via HWCONFIG when the DeviceNet Builder software is calledthrough HWCONFIG in ISPSoft; otherwise, the input and output starting addresses are set via theDeviceNet Builder software when the software is used separately.) The lengths of the mappingaddresses of the input and output are determined by the configuration of all slaves connected toAH10DNET-5A master. Their maximum lengths are both 495 words.For AHRTU-DNET-5A, its input and output starting mapping addresses are automatically allocatedby the master when AHRTU-DNET-5A is added to the master. And the lengths of the input andoutput mapping addresses are determined by the configuration of the modules connected toAHRTU-DNET-5A.For the I/O modules, their input and output mapping starting addresses can be allocatedautomatically or set by users. The lengths of the input and output mapping addresses depend on theconfiguration of the modules.The ranges of the input and output mapping addresses of the modules are limited by those of theinput and output mapping addresses of AHRTU-DNET-5A.
