This library allows to easily read counters from Finder 7M devices connected via ModBus to a Finder Opta, providing a number of built-in functions that simplify the process of reading measurements from both Measurement Instruments Directive (MID) certified counters and custom-configured counters.
The library also includes functions to directly read registers via ModBus and perform conversions. Additionally, using this library it is possible to reset the counters of the Finder 7M.
The code below shows a basic example of how to use this library:
#include <Finder7M.h>
Finder7M f7m;
constexpr uint8_t MODBUS_7M_ADDRESS = 20;
void setup()
{
Serial.begin(38400);
if (!f7m.init())
{
while (1)
{
}
}
}
void loop()
{
Measure inActive = f7m.getMIDInActiveEnergy(MODBUS_7M_ADDRESS);
Serial.println(String(inActive.mantissa()));
Serial.println(String(inActive.exponent()));
}For more details take a look at the example sketch provided with the library.
When using this library keep in mind that:
- The default baudrate is
38400. - The default configuration is
8-N-1. - When writing to registers you should always write one register at a time.
