Using an embedded Anybus Communication Interface in a PLC

Flexible communication is a key successes factor for almost any PLC.  Whether a master / scanner  interface is needed to control the decentralized I/O devices or a slave interface is required for integration of the PLC as a slave into a upper level control network, the Anybus technology from HMS provides the right solution.


Designing a Fieldbus or Ethernet Master / Scanner Interface for a PLC
Via an integrated master / scanner interface it is possible to connect decentralized field devices such as I/O blocks, valves, drives or HMI via the network to the PLC. The network replaces the costly parallel wiring and ensures a reliable and fast data exchange of input and output data between the PLC and the decentralized field devices.

Requirements on such a master / scanner interface include high data throughput, easy configuration and flexibility regarding the network type. HMS fulfill these requirements and offer ready to use embedded master / scanner solutions for Profibus, DeviceNet, CANopen, Modbus TCP, EtherNet/IP and AS-Interface.

Along with the embedded communication modules, HMS offers tailor-made configuration tools that are used to describe the configuration of the network and download it into the master / scanner interface.

CM CANopen Master/Manager for the SIMATIC S7-1200 PLC

The CM CANopen enables you to connect any CANopen or CAN 2.0A devices to a SIMATIC S7-1200 PLC. The module plugs into your S7-1200 and acts as a bridge between the CANopen/CAN devices and the micro PLC. This allows you to choose from a wider range of automation products when designing your system. Available from Q1 2013 this plug-in "in-rack" extension for the new SIMATIC S7-1200 PLC comes with full integration within the TIA Portal software architecture. Contact HMS for more information about integrated "in-rack" Master/Scanner communication modules. Read more about CM CANopen

Designing a Fieldbus or Ethernet Slave Interface for a PLC
Via an integrated slave / adapter interface, it is possible to integrate the PLC as a slave or adapter into an upper level control network. This is a typical application for small and micro PLCs, where the PLC performs data pre-processing and the pre-processed data is transmitted via the fieldbus / Ethernet network to a hierarchical higher ranked control system.

Requirements on such a slave / adapter interface solution include high flexibility regarding the type of network, transmission of small amounts of data, access to cyclic process I/O data and acyclic parameter via the same network interface and low connectivity cost.
