Chapter 5 Profibus-DP Communication
5.1 Overview
Profibus is an open type field bus that the manufacturer selects independently to apply and manufacture (Vendor-independence). Also, It is
used widely for processing automation. DP among them is the most frequently used Communication profile and the network suitable for
FA environment of Field Level and also is suitable for master-slave communication between master automation machine and distribution
slave I/O machine. It is designed to install with low cost and is the most suitable item to replace the existing system such as 4~20mA or Hart
system together with 24V parallel signal transmission to the production automation system.
Smart I/O communication supports Profibus-DP by GM3/4/6 and XGT master module.
(G3L-PUEA, G3L-PUEB, G4L-PUEA, G4L-PUEB, G6L-PUEA, G6L-PUEB, XGL-PMEA, XGL-PMEC).
