Chapter 11 DeviceNet Remote I/O Module AHRTU-DNET Status word of AHRTU-DNET-5A 11.4.4 Connecting AHRTU-DNET-5A to the DeviceNet Network In general, AHRTU-DNET-5A is set through the following steps from successful configuration to normal operation on the network. Hardware Wiring In the hardware wiring, make sure to use the standard cable and connect the terminal resistors of 121 ohm to the two ends of the mains of the DeviceNet network. All node addresses on the network must not be identical and their baud rates should keep the same. Online Scan The scan consists of two parts such as network nodes scanning and I/O modules scanning in AHRTU-DNET-5A configuration.
Before scanning is carried out, ensure that the communication channel is chosen properly and the communication setting in COMMGR is done correctly. Configuration Setting Configuration Setting includes the master and AHRTU-DNET-5A configuration settings. The master configuration contains master scanner module setting (master configuration) and scan list configuration. AHRTU-DNET-5A configuration contains AHRTU-DNET-5A and other I/O module settings. Configuration Download Configuration Download refers to master and AHRTU-DNET-5A configuration download. When AH10SCM-5A exists, AH10SCM-5A serial port data configuration download will be added.
