Visualisation system with an integrated PLC for compact automation solutions.

Lenze has expanded its successful family of HMIs with the option of an integrated Soft-PLC.  The EL100 range of touchscreen HMIs feature a standard Windows CE operating system and now can be supplied with an integrated Soft-PLC to the standard IEC61131.  This creates a solution that is extremely economic, particularly as one device performs two functions, and ideal for compact machinery produced in high quantities and that are therefore price sensitive.

The EL100 touchscreens are available from 5.7 to 10.4 inches and the Windows CE operating system, together with Lenze VisiWinNet visualisation software, speeds up the process of display programming.  All six models can be selected with a low cost option of a Soft-PLC running the industrial standard languages of IEC61131. Compared to the pure visualisation panels, the EL100 PLC versions have twice the memory capacity with 64MB flash and 128MB RAM.  In addition a maintenance free UPS protects against short-term supply interruptions and retained variables are saved on an integrated flash disc.

Interfaces on the EL100 displays are designed to be flexible and allow easy connection with host controllers and other devices.  A CANbus connection suits other Lenze L-force components such as drives and I/O.  An Ethernet connection suits programming from a PC, in addition there are MPI, RS232 and USB ports.

By combining two automation modules into one device, Lenze offers cost savings in terms of purchase price and simplified installation.  Machinery can be made smaller.  The touchscreen HMIs with bright screens and easy to use visualisation software satisfy all the operator requirements.  Addition of a Soft-PLC integrates control functionality at a low cost.
