RicardoRSP Posted October 15, 2021 Report Share Posted October 15, 2021 Hi everyone! First, im asking here after quite a research over this topic, but couldn't find anything solid so far, sorry if i missed any other topic about it. I got access to a Unitronics PLC SM43-J-RA22 that has no Ethernet port on it, so i wonder if i can use MODBUS connection over the Mini USB port that comes with it, or if i can use an USB to Serial adapter to access it over internet, the end goal is to use in a process that will alarm an user (by sms or email) after a certain event, and to be able to access it HMI remotely. What i did so far is to keep connected to a PC using the Mini USB, then use the Remote Operator on it, so i could access the PC remotely and control the HMI from there, but i don't think the alarms would work in the mode. There are other possibitilies other than what i wrote here so far? I appreciate any input about this. Ricardo S. P. Quote Link to comment Share on other sites More sharing options...
