Hello every one i have little problem about scada system on panneaux solaire the problem is i wanna make another interface to show information from server ..
So we used here serial comminecation rs485 modbus
And i can get addressage of All information like exp when i recive 62800 i kn its for curant or voltage and so on ..
So the qst is how to mapping all address i kn with the new one like i kn 62800 for voltage but voltage update each second for exp
So i wanna mapping the new information with old address to know this info for voltage
Hi @addalaabderrahim, if you mean that your Modbus address is 62800, which you use to receive voltage information, then the address for reading voltage will not change. Each Modbus address corresponds to a specific parameter when read, and the data size (whether it’s 1 byte or 2 bytes) depends on the documentation’s mapping of addresses and their respective parameters. I recommend reviewing the documentation to understand the expected data format for each address. Personally, I follow the sequence of addresses to interpret the data received from Modbus. Hope this may help you, best wishes!
Ah yes yes thx man ,i will try mapping all adress and if i get problem i will ask😅haha
