Defines communication aspects of a programmable controller, specifying from the viewpoint of a PC how any device can communicate with a PC as a service and how a PC can communicate with any device. Specifies the behaviour of the PC, providing services on behalf of other devices and services the PC application can request from other devices. Intends to specify how any device can communicate with any device using a PC as a router or gateway.

IEC 61131-5:2000 specifies communication aspects of a programmable controller. It specifies from the viewpoint of a PC how any device can communicate with a PC as a server and how a PC can communicate with any device. In particular, it specifies the behavior of the PC as it provides services on behalf of other devices and the services the PC application program can request from other devices. This bilingual version (2012-08) corresponds to the monolingual English version, published in 2000-11.

This publication is to be read in conjunction with the IEC 61131 series.
