Dear DIVYESH, is the FB250 not available in your CPU or does your CPU not support floating point arithmeticoperations? In second caseyou can purchasean optional package for handling floating point values 6ES5 845-8GP01 "GP115U" (if still available). The package is originaly developed for S5-115U CPU's but will run on95U & 100U as well (just a bit more slower). The other option would be to develop your own blocks. Regards. |

CPU928A supports floating - point operation, so scaling is absolute no problem! Write a FB by yourself! |

Hello BeVee , does this package contains the FB250 he is looking for? I could not find it. Please verify. Regards. Here is the link to the manual of the "Basic Function Blocks" package. https://support.automation.siemens.com/WW/llisapi.dll?func=cslib.csinfo&lang=en&objid=19394653&caller=view Except the scaling of analog inputs & outputs I could not find any general scaling block. What I still not understand is that when he makes a complete upload to the PG, the FB250 is not getting transferrerd? At least the block header or something should be there or not? Regards. |

Hello SolutionFinder, here is the link to the manual: http://www.google.de/url?sa=t&rct=j&q=s5%20cpu%20928%20operating%20instructions&source=web&cd=2&ved=0CEMQFjAB&url=http%3A%2F%2Fcache.automation.siemens.com%2Fdnl%2FTc%2FTc5MTgyMzEA_1085940_HB%2Fpa928ben.pdf&ei=o1KWT4T9L4af0QWSoPW-Dg&usg=AFQjCNHwA4ciQviEmf4I6z4wTfAi8a6CIQ Look at the operation list / arithmetic operations. There you will find examples as well. Do you need to scale an analog input/output signal or do you want to generally scale a value? What are the requirements of your function block? Input parameters and format? Output parameters and format? i.e.: Input Value (real) Input min. (real) Input max. (real) .... .... Regards. |
