KEB launches new safety PLC, I/O modules and softwareKEB America is releasing a new Safety PLC, Safe I/O modules and Safety PLC programming software. All of the new safety products are certified by TUV Rheinland to IEC 61508 SIL3 and EN/ISO 13849-1 PL e.

KEB's Safety PLC is a Fail Safe over EtherCAT (FSoE) master that is designed for use in tandem with the machine's automation PLC to execute and monitor the safety functions of the machinery. FSoE uses a black-channel approach and can be used with other bus systems. KEB's Safety PLC connects with other FSoE slave modules like Safe I/O and servo drives with safe motion functionality.

For monitoring safety devices with the Safety PLC, KEB now offers dedicated Safe I/O modules. Each FSoE slave device has four safe inputs, two safe outputs and four OSSD outputs. Because the modules use EtherCAT for fast, real-time communication, they are also suitable for existing systems or installations that require a scalable system. One FSoE master can control up to 65,535 slave devices.

Programming environment

KEB's COMBIVIS Studio 6 now includes a Safety Editor that can be used together with KEB's FSoE Safety PLC and I/O. This single programming environment enables a programmer to develop the entire machine, including motion control and safety, with one software program. KEB's Safety Editor uses a certified plug-in from CoDeSys and uses function blocks. COMBIVIS Studio is also used to configure KEB's Safe Motion drives, which also support FSoE and Safe Motion functions according to IEC 61800-5-2.

All of the high-performance drives come with EtherCAT as standard. EtherCAT offers scalable, real-time performance that is flexible enough to work in nearly any application. Fail Safe over EtherCAT enables the Safe Torque Off (STO) and other statuses to be safely communicated over the network. This creates new possibilities for replacing discrete safety wiring with a network cable.

The Safety PLC, Safe I/O Modules and Safe PLC programming software are available immediately. For more information go to
