  1. Can't communicate with RSLinx

    Hi, I am trying to go online with PLC and i got an error. The funny part is before I shutdown RSLink, it was lite version and i was able to go online with my PLC. However, When I re-opened RSLinx, It became gateway version and I dont have an access to go online with PLC anymore. I have attached a screenshot. Thanks 
  2.

I have tried by uninstalling and installing the FT View.but the problm still exists. "RSLinx Enterprise" Computer X does not exist in the FactoryTalk Directory.Contact your Administrator for more information.

  3. Hello, For years we had a silo, that was bought from a 3rd party, with a control system that works ( has a fast input and plc scan time ), but has incredible slow feedback to SCADA. Since the silo is off site, often closed or in full operation it's been hard to get the time window to really work on this and get to know the alternative setup. Now lately there is a bit of room to work on it but the history around the issue is vague and the knowledge surrounding rsview and rslinx enterprise is limited, so I'd hope you guys would know a bit more about it after my explanation. So I can narrow down the bottlenecks better at the next visit. Current Setup: PLC: SLC 5/05 16 CPU with ETHERNET Connection with an 747 - SN/B I/O Scanner for field Connected w/ switch to 2 PC's by Glass fiber The PC's used to be in a master slave setup for Rsview, with added engineering stations for the programming. But have been replaced to two new identical PC's. Whether or not this caused the problem is still vague. These PC's both have RsLInx for Rsview version (PR6) RsView Enterprise and RsView Kepware ( for RsLinx Enterprise in Rsview Studio ) The only addition they have from the old setup is that they also have a logix500 programming added to it. In the are some screenshots for the setup. I had limited time. But if you make suggestions on where to look next I might be able to get more. I thought it was weird that the Ethernet setting for the SLC5 CPU seemed to be locked at 10 mbs half duplex. But since the installation was in operation I could not change it. So I need to be sure that it has some importance, before I can shut down the plc for download. Problem: When an operator controls the silo, his input starts straight away. Open a valve or start a dust blower will immediately result in a reaction in the silo. However in the viewer, it will take 5+ seconds to actually get the feedback. This is not only for I/O but also internal bits like setting a motor block from manual to auto will take long to read out. Though the PLC scan time is only 10-20 ms and doesn't have that many crucial parts, the installation works fine. But there have been moments where crucial parts didn't seem to start on screen, while already running in the silo, causing danger in communication. Since it's a small setup I don't see where the lag is coming from. And the network and card seem fine. My question: What is most likely to be the cause of theses communication problems? So I can have a plan of "attack", next visit at the silo. Thanks in advance, Migel
  4. Writing 2D array to RS5K tag

    Is there way to write a VB script that can write an Excel table into a 2D array for RsLogix 5000? I have looked around for proven examples, but so far have come up unsuccessful.
