Chapter 10 DeviceNet Communication Module AH10DNET 10.1 Introduction AH10DNET-5A is installed at the right side of an AH500 series CPU module. AH10DNET-5A and an AH500 series CPU module constitute the DeviceNet master or slave. 10.1.1 Feature Constitutes the DeviceNet master by connecting an AH500 series CPU module and supports DeviceNet protocol. The network configuration software DeviceNet Builder provides the handy graphical configuration interface and automatically scans and recognizes all slaves on the bus. Supports DeviceNet master and slave mode. An AH500 series CPU module could be expanded by connecting 8 AH10DNET-5A scanner modules. Supporting 8 transmission speeds:
10 kbps, 20 kbps, 50 kbps, 125 kbps, 250 kbps, 500 kbps, 800 kbps and 1 Mbps. 10.1.2 Functions AH10DNET-5A can be used as DeviceNet master as well as slave. As a master, AH10DNET-5A can provide the following function. Automatically performing the data exchange with an AH500 series CPU module; users can directly operate the specified register in an AH500 series CPU module to achieve the real-time monitor of the slave. The configuration software can configure the network via the module as AH10DNET-5A serves as the connection medium between DeviceNet Builder configuration software and DeviceNet network. Supports to send the explicit message to monitor the slave through PLC program.
The maximum input and output data length are both 980 bytes. As a slave, AH10DNET-5A can provide the following function. Automatically performing the data exchange with an AH500 series CPU module; users can directly operate the specified register in an AH500 series CPU module to gain the control data of the master and return the corresponding data to the master. The maximum input and output data length are both 1000 bytes.
10.1.3 Specifications AH500 series CPU modules which are supported DeviceNet interface 10-3 Item Specifications Model name AH500 series PLCs Item Specifications Transmission method CAN Electrical isolation 500 V DC Connector Removable connector (5.08 mm) Communication cable Recommend to use Delta standard cables; TAP-CB01 and TAP-CB02. The communication cable should be away from the power cable and the shielded cable should be connected to the ground. Voltage DeviceNet network provides 11~25 V direct current. e.g. 28 mA (Typical value), 125 mA impulse current (24 V DC).
