3、version of EN 61131- 5:2001. It is identical with IEC 61131-5:2000. The UK participation in its preparation was entrusted by Technical Committee GEL/65, Measurement and control, to Subcommittee GEL/65/2, Elements of systems, which has the responsibility to: A list of organizations represented on thi
