ICP DAS has presented a new EtherCAT Master controller running Linux: EMP-2848M. Using the Win-GRAF environment, the controller supports the creation of programs in IEC 61131-3 languages: IL, LD, FBD, ST, SFC. EtherCAT is a high-performance Ethernet-based industrial communication protocol supporting various network topologies.
The EMP-2848M controller allows you to work with 128 EtherCAT slave nodes and control up to 16 axes with a cycle time of 500 microseconds. The PLC comes with the Win-GRAF environment, which allows you to create algorithms in IEC 61131-3 languages. There is also support for EtherCAT, Modbus TCP and Modbus RTU protocols.

Win-GRAF Workbench is a software for developing SoftLogic controllers, which is used for configuration, programming and debugging. The working environment supports all standard programming languages such as structured text, function blocks, ladder diagram, instruction list and sequential function charts.
Win-Graf Workbench supports cold restart, hot restart, and online changes. Multitasking programming possible with task priority and cycle time setting.
