Hi hewking102 There is probably no standard library available for S7-300 + CP340. However it should be possible to write one yourself. First - You need to learn hou to use ASCII ( Freeport ) communication using CP340 Second, -You need to understand the various telegram structures for communication between a controller and SIM42 Third - You need to write your own FC/FB in STEP7 and test the same ( Easier said than done ) Following links would help you : /tf/WW/en/Posts/48225 /tf/WW/en/Posts/63261 http://support.automation.siemens.com/WW/view/en/38471716 http://support.automation.siemens.com/WW/view/en/21738808 Hope this helps Cheers Navnag |
