Dear Support, I would like to connect a BCD code switch and a BCD display to a Siemens S7 PLC. Firstly I would like to see on the BCD display, what I set up on the BCD code switch. I have a few questions regarding this setup. - CPU: 317F - 2PN/DP (317-2FK14-0AB0) - I/O card: SM 323 DI/DO 16xDC24V (323-1BL00-0AA0) - BCD code switch: Flush-mounted encoding switch BCD compl.- SMC-D-137-AK-2 (Material Number from Distrelec: 135-80-644).This is connected from I8.0 - BCD Display: KINGBRIGHT CC56-12EWA M. This is connected from Q8.0. [snip] My second question connected to the BCD display. It has 12 outlet, 4 for ground and 8 for the each segment. I wired to the I/O card first the 4 ground from Q8.0 to Q8.3, than I wired the rest 8 outlet after each other. Can the FC93 standard libary work with this type of BCD display? I couldn't set it up yet. If I wrote QW8 to the output, it doesn't accept it, because I need to wrote double word output there. How can I? I rather wrote down the truth table of it in FC5 (see in attachment), but it is just a half solution,because in that case all the 4 character show the same number (see in the video). I want to control each character of the BCD display with the appropriate character of the BCD code switch. How is it possible. [snip] I hope you can help me.

New question published by AutoGen_4087331 is split to a separate thread with the subject BCD display connected to S7 300: the intensity of the red color changes. Best regards |
