Report Beckoff EK9000 Ethernet Bus Coupler w V130 or V350 in Vision & Samba PLC + HMI Controllers & VisiLogic Software Posted July 16, 2012 Open and close times were too long eh? I was under the impression that these instructions were done in a scan. I am not surprised to learn otherwise. I have looked and I do not see these Fast open and close blocks you reference. I am very interested in these for an upcoming project. Are you saying that the open and close socket instructions have been changed and are now faster / better and are the standard functions in the new software? I looked in the "new Immediate blocks" under "Utils / Immediate" I don't see anything there about ethernet sockets. I don't see anything under "Coms" or "FBs" either. Or are you referring to a subroutine that someone at Unitronics wrote for you? Would be too much to ask for you to post a striped down program that includes your open close sockets? Maybe a subroutine of your fast coms? I went through this same exercise a couple years ago and spent a lot of time on the coms. I could never get it to work the way I wanted it to no matter what I did. Thanks for the information. Well it can't be "done" in one scan. At least not reliably. Mostly because to complete a connection requires some time, and also depends on the one being connected to. I was complaining that it was difficult to share a socket on the Vision product and that I knew it wasn't a result of the slaves I was talking to because I used something else to talk to them and it was an order of magnitude faster. So the delays were in the Uni. The new FBs are much faster and makes sharing a socket much more viable. Especially with the 4 socket limitation. I appologize, but I had wrongly assumed this was released. So I would not recommend using it unless you are willing to be a Guinea Pig for it and possibly limit yourself to a specific OS and Visi release. They may not be "better". It establishes a connection faster, but I am sure to get something you usually have to give something else up somewhere else. I will make you a stripped down version of my socket routine. There is nothing novel going on in any of them, but it has been out in the wild now for a few years on several machines and has proved robust.
