Mikel Posted November 25, 2018 Report Share Posted November 25, 2018 Hi everyone, Am new here and new to unitronics also. I currently purchased the vision 1210 which I wanted to use for simulation. Am using the EX-A2X I/O Expansion module adapter snap mounted on a Din rail. Read a single adapter can connect up to 8 I/o modules only. is it possible to connect more than one Expansion adapters to oplc to enable me to use more I/o modules? if yes how? Thanks guys.

MVP 2022 Ausman Posted November 25, 2018 MVP 2022 Report Share Posted November 25, 2018 Yes there is, but not in a direct connection way. You need to look at the EX-RC1 adapter.

sasdiscos Posted November 27, 2018 Report Share Posted November 27, 2018 Could you not use a snap in i/o as well Steve Quote Link to comment Share on other sites More sharing options...
MVP 2022 Flex727 Posted November 27, 2018 MVP 2022 Report Share Posted November 27, 2018 How much I/O do you need? Careful selection of modules and use of the Snap-In module (as suggested by sasdiscos) can often help when you're on the edge of needing more.

Mikel Posted November 27, 2018 Author Report Share Posted November 27, 2018 Thanks Ausman, am having a look at the EX-RC1. Thanks Sasdiscos, I actually thought of the snap-in I/o but I do not have one currently. I have to order it from my agent and its gonna take a while before it reaches me. but thanks for your suggestion. Hi Flex, am working with 30x digital inpts, 20x digital outpts, 20x 4-20ma analog inpts, 3 RTD's and 10x analog outpts. am using 2x IO-DI16 2x IO-TO16 3x IO-AI8 1x IO-PT400 and 2x IO-AO6X which takes my I/o modules to a total of 10.

Looks like poor module selection. Unless I'm missing something, if you used the following, you would need only 7: EX-D16A3-TO16 IO-D16A3-TO16 IO-PT400 IO-AO6X IO-AO6X IO-AI8 IO-AI8 Quote Link to comment Share on other sites More sharing options...
MVP 2022 Ausman Posted November 27, 2018 MVP 2022 Report Share Posted November 27, 2018 Flex, you mention the larger I/Os. My personal view on this is that Unitronics don't "promote" the larger capacity I/Os enough, and not many people know about them. For instance, when you look at the I/O listings, you see "Digital" and it is very easy to assume that that's it. You are only presented with the smaller I/Os. You actually have to go down past Analogue/Temp etc to reach the higher capacity modules. This is a big failing in my view, and the page needs adjustment to bring it all together. And whilst on I/Os, and relating to my error above about the snap-in, I try to not use snap-ins, rather discrete I/Os for both ease of replacing and likely smaller cost in the unlikely event of it needing replacement in the future. cheers, Aus Quote Link to comment Share on other sites More sharing options...
MVP 2022 Ausman Posted November 27, 2018 MVP 2022 Report Share Posted November 27, 2018 And whilst I'm whingeing, I wish all the I/Os would use plug-in connectors to enable easier changing. And sometimes easier assembly. cheers, Aus Quote Link to comment Share on other sites More sharing options...
Mikel Posted December 1, 2018 Author Report Share Posted December 1, 2018 Sorry I've been away for a while. you are right Flex, module selection was poor. I also agree with AUSMAN. The larger I/o modules need to be promoted more. Thanks to you all. Quote Link to comment Share on other sites More sharing options...
