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.

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

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
