The eVISIO P series from elrest Automationssysteme GmbH is a family of operator control panels that integrate touchscreen HMI operation with a built-in IEC 61131-3-compliant PLC — eliminating the need for a separate controller in machine automation architectures. Programmable via CoDeSys and configured with the eDESIGN HMI editor, these panels handle both visualization and real-time control in a single compact unit.

What models are available in the eVISIO P series?

The P series spans three performance tiers to match different application requirements:

How are eVISIO P series panels programmed?

All P series panels are programmed via CoDeSys (IEC 61131-3) for PLC logic and eDESIGN (or ElaDesign) for HMI screen design, alarms, recipe management, and network visualization. The P412 additionally supports C/C++/C# development via Microsoft embedded visual tools and Windows CE SDKs. Communication with field devices runs over CANopen, Modbus RTU, and Modbus TCP, with I/O expansion possible through the eCOMBO and eROBUSTO I/O systems.

What are the benefits of an integrated PLC panel?

Combining HMI and PLC in one unit reduces cabinet space, simplifies wiring, and eliminates communication latency between separate display and controller hardware. For machine builders, this means fewer components to source, install, and maintain — particularly valuable in packaging machinery, process skids, and distributed automation stations where space and simplicity are priorities.
