Jungletron Posted August 2, 2020 Report Share Posted August 2, 2020 Hi, UniCan is new to me and my primary objective is to get a UniStream 7" to send and receive IOs data from a EX-RC1 attached to 1 io-d16a3-ro16, 4 io-di8-ro8 and 1 io-ai8. CANbus cable is less than 1 meter long. I can monitor and control almost all of the connected IOs except 2 outputs (O65 and O68) in the 2nd io-di8-ro8 (O64 to O71). I would really appreciate some guidance since I am doing this task in a foreign country and I would like to get back to my family soon Thanks in advance for any help!

MVP 2023 Ausman Posted August 3, 2020 MVP 2023 Report Share Posted August 3, 2020 Jungle, it may not help your exact issue, but have a look at Joe's detailed post on how to set EX-RC1s up in the link below. Although it is for Visilogic, it might be of assistance in resolving your issues. Some other areas....... Are all of the components updated to the latest firmware where possible? All power and earth lines done correctly? Locations of I/Os match in physical layout and in the program? cheers, Aus http://forum.unitronics.com/topic/4165-setting-up-two-ex-rc1/?do=findComment&comment=21520 Link to comment Share on other sites More sharing options...
Jungletron Posted August 3, 2020 Author Report Share Posted August 3, 2020 Hi Ausman, All IO modules were working before with a EX-A2X (I think) and a V1210. No mismatch between program and output pins. In fact when trying to turn on O65 or O68 the module pin led does not react. But adjacent pin leds work fine. Although most of the IO data seems to be good is it possible that I used some parameter in the UniCan the wrong way and that mistake is causing this issue ? I have already saw the post in your link (it seems more complicated than my task) but thanks anyway! Kind regards, JT Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted August 3, 2020 MVP 2023 Report Share Posted August 3, 2020 Post your UniLogic and RC1 programs and we'll have a look. Joe T. Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted August 4, 2020 MVP 2023 Report Share Posted August 4, 2020 Further to Joe's request, 16 hours ago, Jungletron said: were working before with a EX-A2X (I think) and a V1210. Are you sure about this? Can you hook the 1210 in again to check? cheers, Aus Link to comment Share on other sites More sharing options...
Jungletron Posted August 4, 2020 Author Report Share Posted August 4, 2020 Hi, Yesterday I started over from scratch and the missing Outputs are now working so previously I probably made some silly mistake in the Unistream program. @Ausman : connecting the 1210 again is not really an option but now we can be sure all the modules are working . My initial suspicion that I used some wrong parameter in the UniCan was probably because I am not familiar to use it. @Joe: So I would greatly appreciate (and also for the benefit of the forum) a quick look at my EX-RC1 program: - Since I have the EX-RC1 attached to 1 io-d16a3-ro16, 4 io-di8-ro8 and 1 io-ai8 , I started with the file in "Examples\Version 900\Project examples\Communications\EX-RC1\EX-RC1 With Analog\EX-RC1 with ATC8" - I then edited the hardware configuration to suit my modules. - Digital inputs and outputs just have a option to add a description but my doubts appeared with the analog inputs: what addresses should I use? (in my initial problem I thought that something might have been overlapping) - So I kept the addresses of the example (1900 .. 1907) and added the 3 analog inputs of the io-d16a3-ro16 in addresses 1908 .. 1910. I think it is working but is this the correct way to do it? - I followed the PLC Training: Remote I/Os via EX-RC1 | UniLogic for UniStream by Unitronics video and my next doubt was in the UniCAN Send parameters: I had to change the example file to 1016 Source Start Address ( is this determined by "Rx Start Vector" in UniLogic program?) - Another question I have is what is the objective (or differences) of rung 7 and 8 in the IN module of the example since I can connect with my IOs just using rung 8? (or should I be using rung 7 instead?) I see that the UniCAN Send parameters are different ... - At this time the UniStream program is just exposing the Inputs and controlling the Outputs. I appreciate some insight about these topics so I can leave everything running smoothly and be better prepared for other UniCAN applications. Kind regards, JT JT_EX-RC1_HWC_v06.ulri JT_EX-RC1_v06.vlp JT_v06.ulpr Link to comment Share on other sites More sharing options...
