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. Anybus-M modules from HMS fulfill these requirements and offer ready to use embedded master / scanner solutions for Profibus, DeviceNet, AS-Interface and EtherNet/IP.
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.

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.
Anybus communication modules from HMS fulfill these requirements. While Anybus-CC modules can be inserted into the PLC at every point of the delivery chain between the PLC manufacturer and the end customer, Anybus-S modules are built into the housing during production of the PLC.
Plug-in communication modules contained in a robust plastic housing with a form factor similar to a compact flash card. Anybus-CC modules feature the latest Anybus technology combining high performance and low prices.
