10. Specifications ..................23 Product Compatibility The Modbus TCP Interface is compatible with the following AuCom soft starters: • CSX – 24 VAC/VDC and 110/240 VAC control voltage. The Modbus TCP Interface is not suitable for use with CSX starters using 380/440 VAC control voltage.
Page 2: Warnings
USER MANUAL 1. Warnings WARNING For your safety, isolate the soft starter completely from mains voltage before attaching or removing accessories. WARNING Observe all necessary safety precautions when controlling the soft starter remotely. Alert personnel that machinery may start without warning. 2.
Page 3: Installation
USER MANUAL 3. Installation CAUTION Remove mains and control voltage from the soft starter before attaching or removing accessories. Failure to do so may damage the equipment. 3.1 Installation Procedure 1. Remove control power and mains supply from the soft starter. 2.
Page 4 USER MANUAL To remove the interface: 1. Remove control power and mains supply from the soft starter. 2. Disconnect all external wiring from the interface. 3. Fully pull out the top and bottom retaining clips on the interface. [A] 4. Pull the interface away from the soft starter. 3.2 Soft Starter Connection The device is powered from the soft starter.
Page 5 USER MANUAL 3.3 Network Connection Ethernet Ports The device has two Ethernet ports. If only one connection is required, either port can be used. Cables Use Category 5, 5e, 6 or 6e cable to connect to the device. EMC Precautions To minimise electromagnetic interference, Ethernet cables should be separated from motor and mains cables by 200 mm.
Page 6: Device Configuration
USER MANUAL 4. Device Configuration NOTE The Error LED flashes whenever the device is receiving power but is not connected to a network. The Error LED will flash occasionally during the configuration process. 4.1 Overview The Modbus TCP Interface is configured with a static IP address as default. To avoid IP address conflicts and to ensure successful deployment, we recommend that the device is connected directly to a PC or laptop to configure the IP address, before connecting to the network.
Page 7 PC must both be connected to the Ethernet network. The Ethernet Device Configuration Tool can be downloaded from www.aucom.com. NOTE If your PC has a firewall enabled, you must add the tool to the list of authorised programs.
Page 8: Plc Configuration
USER MANUAL 5. PLC Configuration The PLC must be configured to map registers within the interface to addresses within the PLC. Example mapping of PLC registers to registers within the Modbus TCP Interface (Target): The device must be configured directly in the PLC. No additional files are required. 6.
Page 9: Operation
USER MANUAL 7. Operation The Modbus TCP Interface must be controlled by a Modbus client (such as a PLC) which complies with the Modbus Protocol Specification. For successful operation, the client must also support all functions and interfaces described in this document. 7.1 Device Classification The Modbus TCP Interface is a Modbus server and must be managed by a Modbus client over Ethernet.
Page 10: Modbus Registers
The Modbus TCP Interface supports two modes of operation. • In Standard Mode, the interface uses registers defined in the Modbus Protocol Specification. • In Legacy Mode, the interface uses the same registers as AuCom's Modbus Interface. Some registers differ from those specified in the Modbus Protocol Specification.

Page 21: Network Design
USER MANUAL 9. Network Design The device supports star, line and ring topologies. 9.1 Star Topology In a star network, all controllers and devices connect to a central network switch. 9.2 Line Topology In a line network, the controller connects directly to one port of the first interface. The second Ethernet port connects to another interface, which in turn connects to another device until all devices are connected.
Page 22 USER MANUAL 9.3 Ring Topology In a ring topology network, the controller connects to the first interface, via a network switch. The second Ethernet port of the interface connects to another device, which in turn connects to another device until all devices are connected. The final device connects back to the switch.
