Reading via RS485 ModBus network from ESP32 the electrical conductivity value on a Siemens S7 1200 PLC
Budget: €30 – €250 EUR
According to the attached diagram it is necessary to measure the electrical conductivity value with an ESP32 and via RS485 Modbus transfer the value to a Siemens S71200 PLC.
In addition to the creation of the software, the project must be tested online with the PLC and the acquisition system as per the diagram.
The communication parameters are 9600,N,8,1 and the slave is number 2
