Всем привет! Столкнулся с такой проблемой, нужно читать данные с CPU 315-2 PN/DP, (залитый с ТИА), в CPU 414-3 DP (залитый со СТЕП 5.5) по профибасу. В 400-м в НетПро добавил 315, ID поставил 5, все скомпилировалось и загрузилось в 400-ый, от 315 программы нет, есть только DB который нужно прочитать. В НетПро у 400-го нажимаешь онлайн, показывает связь ОК. Пробую функцию GET FB14, настраиваю как в примерах у сименс и на Ютубе, но блок не работает и с права на выходах блока STATUS 000С, что типа плохо, так же ERROR - 1. Подскажите что не так делаю. За ранее спасибо!

Hello! Faced with such a problem, you need to read data from CPU 315-2 PN / DP, (filled with TIA), in CPU 414-3 DP (filled with STEP 5.5) on a profibus. In the 400th in NetPro added 315, ID put 5, everything compiled and loaded into the 400th, there is no program from 315, there is only a DB that needs to be read. In NetPro, at the 400th you click online, it shows OK. I try the GET FB14 function, I set it up in Siemens and Yutube examples, but the block does not work from the right on the outputs of the STATUS 000C block, which is bad, also ERROR is 1. Tell me what I am doing wrong. Thank you in advance!

Check an example with PROFIBUS Connection
DP link between CPU 315-2DP (slave) and S7-400 (master) with STEP 7 V5.3

Here is an example with Step7 5.3 but is the same in 5.5

It's not clear ..do you use a combination between TIA Portal CPU315 and S7 400 Step7 5.5?
How do you program the function blocks FB14 "GET" and FB15 "PUT" in the S7 program of the S7-300 in order to transfer more than 160 bytes of data?
