Talk:List of programmable logic controller manufacturers

The List Describe Programmable Logic Controller
I am an experienced engineer with Programmable Logic Controller and the list here described Programmable Logic Controller. They are NOT Power line communication. Zawthet (talk) 16:08, 18 July 2015 (UTC)
 * So why not add companies that you think are in the Power line communication space? Ottawahitech (talk) 22:19, 4 September 2015 (UTC)

This list is a mess
The title says "PLC", which is ambiguous. Shortly after it was created, "PLC" was disambiguated to stand for "power line communication", but then in February 2017 that was abruptly changed to "programmable logic controller", so as a result this list is a mix of manufacturers of both kinds of equipment.
