1、Gateway for XIP - Unitelway Schneider PLCRev 1.21 of 29Technical note n15Revision1.2 Last Update2004-05-11 DeviceW330Gateway for XIP - Unitelway Schneider PLC1 PurposeThis application note describes how to set up a remote collaboration. A remote collaboration consists in configuring, programming or
2、monitoring a PLC from a remote location, without the need of connecting directly the PC to the PLC. A remote collaboration therefore involves a TCP/IP connection and eventually a router, depending on the protocol used by the PLC. In this document, well configure a complete remote collaboration syste
3、m with a TSX Premium; the PL7 Pro software and, of course, an W330 as a router. The TSX Premium uses the Unitelway protocol. Three cases of remote collaboration will be treated: A direct connection to the W330 by Ethernet. A direct connection to the W330 using a phone line. With this topology, the W
4、330 IP address is known since it is established with your own PC at the PPP connection time. A connection to the W330 using Internet and callback. This kind of connection can be used with callback: we call the W330 and let ring a certain amount of time and we hang up. After a specified amount of tim
5、e, the W330 connects to the an ISP using its phone line. In this case, the W330 IP address is not known so that the W330 must publish its address, by mail for instance. This document will start with the first topology, then, when this configuration is running, the changes needed for the second one w

A direct Ethernet connection will be used to describe the global setup. After this configuration is working, the changes for the phone and Internet topolo

We also assume the reader has some knowledge of the PL7 software.1 Be careful that the D(B) signal corresponds to the A signal on the W330 and the D(A) corresponds to the B of theW330.Gateway for XIP - Unit

The purpose of some of the steps is to test what has been
11、set up so far. Those steps are therefore not absolutely necessary but can be really useful to localize a potential problem. The stets are: Setting up a test program in the PLC using a direct Unitelway connection PC ? ? PLC W330 Unitelway configuration Set up a tag to test the Unitelway configuration
12、 Configuring the W330 for XIP usage Installing and configuring the XIP driver Using the Remote CollaborationAfter each steps, a small test will be described to check the step has been executed correctly.Gateway for XIP - Unitelway Schneider PLCRev 1.24 of 29Gateway for XIP - Unitelway Schneider PLCT
13、echnical note n153 PLC ConfigurationWe will put a small program in the PLC so that we will be able to test the connection between the W330 and the PLC in the next section. To first set up the PLC, we will need a direct connection between the computer and the PLC. To do this, connect the PLC terminal
14、 port to the PC serial port (cable TSXPCX 1031 for instance). Once this is done, open PL7 PRO.3.1 PLC Test programPLC ? ConnectThe information is downloaded from the PLC to the PC and a screen looking like this appears.Figure 2: PL7 PROIf you already have a program installed in the PLC, save it. The
15、 program we will create contains a simple counter. We will use Ladder to build it.Gateway for XIP - Unitelway Schneider PLCRev 1.25 of 29Gateway for XIP - Unitelway Schneider PLCTechnical note n15Create the following program as a master sectionFigure 3: Test Program (Ladder)Confirm the program, disc
