ok i just dug two siemens TI505 series plcs out of the junk yard they work as far as i know i powered them up and all but i dont know how to get it to hook up to a computer for programming. i do also have a siemens sicomp pc32r computer and i seems to boot up but i cant get video out of it because it doesnt have a vga connector . i know these few items are as old as computers themselves but i like my old antiquated equipment such as my large collectionis of AB slc plcs. so any information as to how to use the equipment would be awesome thanks
