Hi all very new to plc programming all self taught to probably a lot of mistakes background I am a tunneling electrician mostly shot cret lining have a hald decent electrical back ground. I started programing with a plr schneiders zelio have designed and built a few panels useing zelio however I have started a project wich hopfully will broaden my plc knowledge I am using schneiders m221(TM221CE40T) PLC with a (tm3D116/G) digital expansion module and a (TMC2AQ2C) analog output cartridge programmed with so mashine basic and will also be using schneiders magelis HMIS5T touch screen programed with vijeo designer 6.2. All digital in/outs etc i have enough knowledge to comeplete this section of my project but I am coming unstuck when comes to analog inputs and out puts I have tried sourcing what info I can online YouTube etc other than schneiders own tutorials. i am struggling to grasp somashines software I know what I want to do if was using an arduino I could write the code but I'm not 2 things I'm trying to do 1 is use the analog output to control a 3 phase speed controller from the hmi rather than using a 10k pot so just need the 4mA to 20mA output to feed straight i to the controllers terminals and the 2nd thing I want to do is use a pnp proxy on a 4 prong pully mounted pic up to give a rpn read out on the hmi if could get a few pointers more on the plc side first then will have a go at setting the hmi up before I seek help if needed thanks in advance
