FrutigerAG Posted May 12 Report Share Posted May 12 Hello I am planning a project with a V130 where I need to control four devices with one RS232 port each. I can equip the V130 with a maximum of two RS232 ports (1x existing, 1x extension). Does anyone know a technical solution with which I can query/operate four RS232 ports simultaneously and independently? Thanks. Marc Quote Link to comment Share on other sites More sharing options...
arnie Posted May 12 Report Share Posted May 12 I’ve used an RS-232 buffered smart switch from B&B Electronics with good results. The 4 port is the one I’ve used. Quote Link to comment Share on other sites More sharing options...
Cam Posted May 12 Report Share Posted May 12 I don't believe there's a good way to do that with a V130. Have you looked in to if the devices support RS-485? or a Isolated Addressable RS-422/485 to RS-232 Converter so you can assign the devices an address in a RS-485 network that the PLC would use to communicate with them.

MVP 2021 kratmel Posted May 12 MVP 2021 Report Share Posted May 12 This is one of the possible solution - use Unisream with 4 RS232 (Rs485) com modules Quote Link to comment Share on other sites More sharing options...

Pavel_setnicar Posted May 13 Report Share Posted May 13 Instal ethernet (LAN) card V100-ET2 from unitronics into your PLC and buy one of this: https://www.aliexpress.com/item/1005003676953168.html?spm=a2g0o.productlist.main.13.6cc7m3pcm3pc3Z&algo_pvid=da738608-6535-4114-b3d5-ddef7a5cb6c3&aem_p4p_detail=202305130045542171265101056280006842707&algo_exp_id=da738608-6535-4114-b3d5-ddef7a5cb6c3-6&pdp_npi=3%40dis!EUR!71.26!61.28!!!!!%40212244c416839639543775227d073c!12000026759305831!sea!SI!111006486&curPageLogUid=XOQHhc15r2vw&ad_pvid=202305130045542171265101056280006842707_7&ad_pvid=202305130045542171265101056280006842707_7 I done it before and it works.

Do you have a link to a manual, or how did you figure out how to use it? Joe Tauser Quote Link to comment Share on other sites More sharing options...

FrutigerAG Posted May 15 Author Report Share Posted May 15 Thanks for the numerous solutions 🙂 I try it now once with the 4-channel port (from ebyte) via the Ethernet interface. If it should not work, I can always work with two V130. Quote Link to comment Share on other sites More sharing options...

Thank you 😉 Do you have a small example program? That would probably make it a little easier for me.... Thanks a lot! Quote Link to comment Share on other sites More sharing options...
