what is the platform ? and the version of modbus-arduino and modbus-serial ?
#include <Arduino.h>
#include <ModbusSerial.h>
ModbusSerial mb (Serial, 10);
const uint8_t NbOfIsts = 24;
const uint16_t FirstIsts = 197;
const uint32_t IstsValues = 0xB5DBAC;
void setup() {
Serial.begin (38400);
mb.config (38400);
for (uint8_t i = 0; i < NbOfIsts; i++) {
mb.addIsts (FirstIsts -1 + i, (IstsValues & (1 << i)) != 0);
}
}
void loop() {
mb.task();
}
Reading test with mbpoll :
C:\Users\pasca>mbpoll -a10 -b38400 -t1 -r197 -c24 -1 -v com6

The bug is confirmed, investigations in progress.
what is the platform ? and the version of modbus-arduino and modbus-serial ?
Arduino 1.8.15 Arduino AVR Boards 1.8.6 Arduino Mega2560 modbus-arduino 1.1.1 modbus-serial 2.0.4
Attach my test code
THANKS. Could you update modbus-arduino to version 1.1.1 and verify that your problem is gone ? https://github.com/epsilonrt/modbus-arduino/archive/refs/tags/v1.1.1.zip

Tested version 1.1.1 and verify. It work normal now. Thanks
It should return 0D 02 02 FF FF but coil 8 looks wrong?
