Hi, I want to scale an alaog output value. I got 0% to 100% and I want to scale the analog output from 4 mA to 20 mA. Are there a block that does this ? Gustaf |

Hello Gustav; The block FC 106 "UNSCALE"(from the instruction library TI-S7 conversion in Step 7) is the appropriate function for sending an analog output signal. You can have more information in this earlier discussion on the forum: Analog signals Hope this helps, Daniel Chartier |

It could be S7 code too though in form of FC108 or FC109 from the "S5-S7 Converting Blocks" library. These would/could be used ifyou for example haveS5 I/O racks with AQ cardsconnected to an S7-400 (IM463-2 in the S7-400 CRand IM314 in the S5 ER's). If that is indeed the case, the inbuilt context sensitive help on FC108 and/or FC109 via <F1> will (should) give Gustaf_the answers he is seeking. I hope this helps, butif not, I suggest Gustaf_will give us more details about his system (e.g. is it an S7 with S7 AQ cards, or S7 with S5 AQ cards or S5 with S5 AQ cards,CPU type, AQ cards typeetc. etc.). |
