In terms of industrial buses, I believe everyone will not be unfamiliar with EtherCAT. It is an open bus protocol based on Ethernet with low latency, high response and high reliability. And because of its open characteristics, different component manufacturers can use the protocol to develop their own control products, but also make the end user in the choice of components have more flexibility.

Failsafe Over EtherCAT (FSoE) is a SIL3-level functionally-safe data transfer protocol based on EtherCAT. The communication principle is to add security-related protocol frames to traditional EtherCAT messages, ensuring the characteristics of EtherCAT bus and adding functional security features.

MVME712/M In the face of the growing demand for EtherCAT security, Peel Magnetic recently announced the PNOZ m EF EtherCAT FSoE security bus module. In addition to EtherCAT protocol slave station, the module can also be used as FSoE protocol master or slave station, which can be described as a variety of functions in one. Used with the PNOZ m B1 safety controller for full standard and safety control based on EtherCAT.

The main technical specifications of PNOZ m EF EtherCAT FSoE are as follows

FSoE:
•• Maximum cycle time 10ms
•• As the primary FSoE station, a maximum of 60 secondary FSoE devices can be connected

MVME712/M 

•• As an FSoE slave station, you can connect to up to 4 FSoE master stations
•• Supports up to 512 bits of security output and security output signals
•• A minimum of 8 bit secure input /8 bit secure output signal can be transmitted per connection

EtherCAT:
MVME712/M • Supports up to 128 bit standard input /128 bit standard output signals

In terms of system construction, as long as the third-party controller supports the EtherCAT master protocol, it can be paired with the PNOZm EF EtherCAT FSoE security module and PNOZmulti control system. As a result, Ethercat-enabled PLCS, drives, robots, CNC and other systems make it easy to implement standard and secure “one-grid” solutions. A typical system structure diagram is shown below:

For users, due to the use of a single bus complete solution, whether configuration, wiring or post-maintenance, can significantly save time and effort.
