Dear Fritz, I really didn't understand: "program your S7-300 as if it is an S7-400 and directly use SFB14/15 GET/PUT blocks and it will work" . What should i configure in program when i call FB14/FB15 and to use as SFB14/15 Thanks so much. Vũ Vinh ------------------------------------------------------------------------------------------ |

hi, he means, there are 2 kind of blocks. in a S7-300 you need to use the FB14/15 and in S7-400 you need to use the SFC14/15. But in S7-300 there are also 2 variants of PUT/GET. One for the communication over the internal interface and one for communication over CP.
Sample Program: S7 Communication with blocks FB14 ("GET") und FB15 ("PUT") of the CPU 317-2PN/DP Sample program: S7 communication with the blocks SFB14 ("GET") and SFB15 ("PUT") with S7-400 hope this helps, regards, |

Hi vuvihn11, You could use empty box block and write "in it" SFB14 or SBF15. It work for me. I hope it will help you. ;) Regards |
