PLCopen TC6

PLCopen is a vendor- and product-independent worldwide association defining international standards for various topics related to control programming. For this purpose, PLCopen has 6 technical committees.

The goal of the sixth committee (TC6) is to define a standard file format, based on XML, for exchanging programmables controllers programmed using IEC 61131-3 languages. Beremiz uses this file format for saving the PLC programs of projects.
