Posted 4 Feb 2020 Hi I have this kind of plc (al2-24mr-d ) , can i link it to one of the hmi programs ? like scada ? thanks Share this post Link to post Share on other sites
Posted 4 Feb 2020 I Doubt that. But you can connect a GOT. If you want to connect is to SCADA than I would use a small GOT. The SCADA can than connect to the GOT Like a system Q. In the GOT you link the Alpha Devices to the virtual system Q devices Share this post Link to post Share on other sites

Posted 1 Mar 2020 Documentation is sparse but I don't see a single modern protocol listed for that thing. I says Dedicated Protocol and lists one PC windows application it can communicate with. I wouldn't put money on getting a GOT or any other HMI/scada to read it. Share this post Link to post Share on other sites
Posted 2 Mar 2020 (edited) This is what you do. Just choose a small GOT like an GT2103 with ethernet connection. Make the general setup where you choose the Alpha 2 to connect. For the second channel choose the microcomputer. (now the GOT will act as a System Q or See formats) Now you will still need to copy variables between the Alpha and the GOT(virtual Q) devices so you can use the Device data transfer settings for that. The tranfer setting speed for an Alpha is min 500msec so you wil have a small delay on your SCADA. But this is an Cheap & easy way to be able to connect old hardware for which no ethernetcard is available but has a serial connection available and a driver in the GOT. This is how it would work so you know it is possible but ... the Alpha is only a ver small controller. Why not just replace it with a small FX5 or something which already had an ethernet connection.

Posted 2 Mar 2020 Nice walkthrough. One of the other vendors of one of my clients uses almost nothing but Mitsubishi [mostly VFDs]. The guys at the plant prefer our work but the beancounters love the price of those Mitsubishi VFDs. Can't really blame them, they beat my price using Fuji's at 55% of my cost. Insane! Ether way I expect I'll end up having to work on one sooner than later. Share this post Link to post Share on other sites
Posted 2 Mar 2020 Thanks. :) Maybe you will work with the new FR-E800. Should be an even more competitive model.https://www.youtube.com/watch?v=DQrrdCOHSdc I haven't used one yet but I would like to test the corrosion detection function. Share this post Link to post Share on other sites
Posted 3 Mar 2020 (edited) Last one was FR-F800. The Ether/IP card wasn't the friendliest I've met. The guys that built it put a ModbusTCP card in and left the Ether/IP card requested in the bottom beside the reactor in all four units. They were running them for about a week in hand that way.

Posted 3 Mar 2020 I can imagine that. Ethenet/IP is not that big here so don't have the experience. Usually easiest to use the use the vendors network when possible Share this post Link to post Share on other sites
Posted 3 Mar 2020 Allen Bradley to Mitsubishi doesn't leave other options. Share this post Link to post Share on other sites
Posted 3 Mar 2020 Yep than you have to. I try to avoid network converters myself . Share this post Link to post Share on other sites
