In the factories have many variation and complex processes, one of methods that used to solve the problem is control system, Factories use Programmable Logic Controller (PLC) as control system. PLC have many types and specifications or different functions relationship with other vendor that produce. It is possible in the factory have two or more PLC with difference vendor, in order to get for some PLCs can work effectively and efficiently then do integration, process divided some parts and each PLC can do one part. Communication media that used is Local Area Network (LAN) and Human Machine Interface (HMI) Touchscreen. The result of this Final Project is HMI as medium between 3 multivendor PLCs, Modicon, Omron , Siemens work integrately, with communication respond result is recorded is 1.169 seconds (1 second, 169 milliseconds) Keywords: PLC, LAN, HMI Touchscree
