Hello, Lot of questions 1. correct. 2. Have a look at: Where and when do you need peripheral addressing? 3. if you use the per. input you can wire it directly. 4. in simatic you have M-register, DB's to store youre bits/bytes etc. and you can store local in functions (temp) . A M bit is Mx.x , 8 bits is MBx, 16 bits MWx and 32 bits is MDx, see attached picture for more details. 5. if the hardware supports it it can be -27648 to 27648. For some examples with your CPU have a look at: Sample programs for CPU 31xC Technological Functions V1.0 regards, Marcjan |

Hello, For such an application, you can convert the internal command (0.0 to 100.0) to value to be transferred on the analog output module by using FC106.Check the attachmnet for more information and a sample. Best regards, Hamid Hosseini AttachmentFC106.pdf (32 Downloads) |

To hdhosseini, Thank you, the document was a lot of help :)
didn't know that im using a PID so im using OB85 for cyclic interrupt, i think in that block along with PID calculation im going to move that to a M registern and then ill use this register on another blocks of the program. Thank you :) |
