CANopen

The GW-7433D-G bridges CANopen networks and Ethernet-based control systems. On the field side it operates as a CANopen master, using PDO and SDO services to communicate with slave devices. On the plant side it appears as a Modbus TCP server and a Modbus RTU slave, so an existing CANopen installation can be monitored and controlled from any Modbus TCP client or Modbus RTU master.Slave devices are predefined using the manufacturer's utility software. At start-up the gateway collects the required information from those slaves. It supports up to 20 CANopen slave devices, and up to five Modbus TCP clients can access the unit at the same time.The listen mode lets engineers monitor CANopen slave data without taking part in the network traffic. Slaves can be added or removed on line, and CANopen status, slave and gateway communication states, and disconnections can be queried through Modbus commands.ApplicationsControl systemsBuilding automationFactory automationDistributed data acquisitionWind turbine monitoring and control, integrating large inverters and PLCs

The I-8123W-CPS-G adds a single CANopen slave port to supported ICP DAS PACs, so an engineer can connect a WinPAC, ViewPAC or XPAC controller to a CANopen network as a slave device. It is a practical choice where a PAC needs CANopen connectivity without a separate gateway, and it suits distributed real-time control in industrial, building and vehicle applications.The module follows the CiA DS-301 v4.02 specification and supports node IDs from 1 to 127, with a programmable slave node ID. Node Guarding, Heartbeat Consumer, EMCY, and PDO/SYNC behaviour can be configured through event triggers and several PDO transmission modes, while dynamic PDO mapping and single-byte PDO output help keep process data updates efficient.Ordering code I-8123W-CPS-G CR. The CAN interface uses an NXP SJA1000T controller with a built-in 120 Ω terminal resistor, a baud rate range of 10 k to 1 M, and 2500 Vrms photo-isolation on the CAN side. Vendor-supplied eVC++, VB.Net and C# demos are provided to help with application development.ApplicationsIndustrial automationBuilding automationVehicleMaritimeEmbedded control networks

The I-8123W-G CR adds a CANopen master port to compatible ICP DAS WinPAC, ViewPAC and XPAC controllers over the parallel bus. It is intended for engineers who need a CANopen master on an existing PAC without a separate gateway, and it communicates with slave devices using the CiA 301 v4.02 specification.The module uses an NXP SJA1000T CAN controller with an 82C250/251-class transceiver, and provides a single CAN port on a 5-pin screw terminal connector with a built-in 120Ω terminating resistor. Scan, listen and event-monitoring functions help with commissioning and supervising a live network, while dynamic PDO mapping and several SYNC modes allow the process data exchange to be tuned to the application.Electrical isolation is rated at 3000 VDC for DC-to-DC and 2500 Vrms for the photo-coupler. The module also supports the CANopen Motion Library, which follows CiA 402 and covers position, velocity, torque and synchronised control. Drivers are provided for WinPAC, ViewPAC, XPAC and XPAC-CE6, with SDK support for eVC++4.0, VC++, VB.net and C#.net.ApplicationsIndustrial machineryLaboratory equipment and researchRestaurant appliancesMaritimeMedicalSpecialty vehicles

I-87123-G is a single-port CANopen master module for engineers who need a dedicated master controller on a CAN bus network. It follows the DS-301 v4.02 specification and handles network management, scanning of all nodes on the network, and monitoring of EMCY, Node Guarding and Heartbeat events.For process data, the module offers event-triggered, remote-requested, cyclic and acyclic SYNC of PDO modes, along with dynamic PDO mapping. SDO communication supports the segment protocol, and the module can also run in master listen mode. The baud rate range is 10 k ~ 1 M, and a 120Ω terminating resistor is built in.The module is isolated, with 3000 VDC for DC-to-DC and 2500 Vrms for the photo-coupled channels. It is rated for an operating temperature of -25 ~ +75 °C and includes PWR, RUN and ERR status LEDs. Driver support is listed for WinPAC, ViewPAC, XPAC and XPAC-CE6, and the SDK covers eVC++4.0, VC++, VB.net and C#.net.ApplicationsIndustrial MachineryLaboratory Equipment & ResearchRestaurant AppliancesMaritimeMedicalSpecialty Vehicles
