Dear MauricioRC,
That's exacly what you need to do. Analysing and trying to understand how your software works. We don't have your program, we don't know how it is done. Without it will be difficult for us to give you some guide except some general information. I hope you studied already the Modbus Master RTU manual. Thena good idea would be trying to locate the send/receive function blocks in your program. I am sure from there you willbe able to trace more things out. Best Regards. IT WOULD BE NICE IF YOU DONT REPEAT YOUR REQUEST IN MULTIPLE POSTS. YOU CREATE EXTRA WORK FOR THE MODERATOR TO DELETE THEM. |

Dear MauricioRC,
Just in the same it is done for all other meters.
The slave address has to be different to all other existing slaves. From the manual of the device you should be able to find out how to check the configuredaddress. It could be possible that you will have to assign a freeaddress at the device. As per your information table: Function code: 3 (Read Holding registers) Start address: 3999 (Modbus address 44000) Lenght: 18 (44000to 44017) Best Regards.

Dear MauricioRC, without having the software in front of me it I cannot help you. Even I need to see and study yourprogram in order to understand how it is working. Only after that study I can tell you whatto do. You already said that you studiedthe manual of the Modbus RTU Master butwithout any help. I suggest you archive andupload us your program and we will look at it. Which software and version are you using for programming (STEP7/TIA)? Best Regards. |
