Hello, ok. Some first study materials are here. My attachment shows probably your exactly expected printer specification and my tips. Next is some search result from Search about S7-1200 and CM1241 communication problematic: Search results Forum about S7-1200 and CM1241 serial communication Next what I recommend is check some good ASCII table on web, you'll need this with your project. Next recommendatrion is check on PLC system manual about CM1241 serial port pins and check some informations about cables used for serial data exchange. It is possible that inside that Result of search you can find some FAQ or other users project where some typical communiaction task is described. This Forum si full of Topics with this problematic and also FAQs from Siemens. Here is also link to your printer support page where also other useful SW are, especially I expect that Tool with some exact view of tickets preparation is very interesting and can be useful to you generally. maybe there is also some option inside to see exact ESC char/byte sequence what you need send out of your CM serial port to print that (one tip already with ASCII table will be required with this tests) but you need check that. Then use of any serial SW on PC like Hyperterminal or Hercules can be used to check outgoing chars from this SW to your printer for initial tests without PLC. I see you simply no experienced in this (you also said that) so first tests need to be prepared via this system. If you'll be more experienced what you need send via PC app to printer then your PLC code preparation can be more easy. |
