Please also see the attached screenshots. I need to find how / where the values from 40 to 52 in DB100 are modified in the PLC logic and also how / where these values are transferred to the two DCM drives where the control the speed when the drives are turning in manual mode. I have searched for the values from DB100.DBD40 to DB100.DBD54 - but none of them are found in the logic. How are they transferred to the drive and what am I doing wrong?

Hi Hati, Thank you for answering. Please also see the attached screenshot. Previously I had only searched for the specific addresses (DB100.DBD40, DB100.DBD44, DB100.DBD48,and DB100.DBD52). But now I have also tried searching for the whole DB. Since it is probably the main data DB for the PLC logic I anticipated that it was found in many of the FB's and FC's and it IS in several. But when looking at my "Go to location" results it seems it is only finding M2.0 (which is a permanent zero). I cannot even find M2.0 in DB100. Is it correct it is there or what am I doing wrong? Is it correct I am only searching for that and if so how do I search for all the values (with emphasis on F10_00_SP6, F10_00_SP7, F10_02_SP1 and F10_03_SP1)?

Hi Hati, Thank you for answering. Please also see the attached screenshots. Yes - I found that a bit earlier also but - as far as I can see - the address areas DB100.DBD40, DB100.DBD44, DB100.DBD48,and DB100.DBD52 are not used in any of the places. Is this not correct? I forgot to mention that it is a busy machine so it will be difficult to test "Is the speed changing when you modify the value of DB100.DBD40?". Since it is in the driives the speed will be lowered it seems difficult to test with PLCSIM?

Hi Prof. Frink, Thank you for answering. I have tried following your advice but with very limited success. IF I am so lucky that someone will take a look for me I have attached the project (or at least the main PLC from the project). Unfortunately the file was to big to attach when it was just zipped so I had to use 7-zip. Then the format from 7-zip is not allowed by the forum so I had to rename it to .zip. So - in order to get the project in a form that can be opened first it must be renamed from .zip to .7z and after that it must be unzipped to a folder named "Fa2plc01". If you need it 7-zip is free and can be downloaded from: https://www.7-zip.org/download.html or https://portableapps.com/apps/utilities/7-zip_portable Here is my comments / results from trying to follow the advice from Prof. Frink: FB1003 (because it is a "drive FB") I dont see any "open" or use of DB100 FB1110 (because it is a "drive FB") I dont see any "open" or use of DB100 FB1113 (because DB192 has a "similar" symbolic name and DB192 mentions the "tørn fra +A13 which I am looking for) I dont see any "open" or use of DB100 FB1163 (because it is called "COMM_G120_1") I can see some bits to or from a controlword but nothing relating to the speed settings in DB100 - this COULD have something to do with the "manual turning speed" which I need to modify - but I cannot really understand how it works? FB1164 (because it is called "COMM_S120_1") I can see some bits to a inverter but nothing relating to the speed settings in DB100 - this COULD have something to do with the "manual turning speed" which I need to modify - but I cannot really understand how it works? FB1165 (because it is called "COMM_G120DP_F_1") I can see some bits to a inverter but nothing relating to the speed settings in DB100 - this COULD have something to do with the "manual turning speed" which I need to modify - but I cannot really understand how it works?
