Hi Mikhail,
I try to input your given formula, but my server turn error.

function double MyFunc()
{
 switch ((int)Cnl)
 {
  case 3:
   return 1;
  case 4:
   return 2;
  case 5:
   return 3;
  default:
   return 0;
 }
}

Is there something wrong?

But, could you explain what this code mean? I want to understand it, so I can use for another alarm.

Hi Mikhail,

I need to read alarm from register offset 2048. But manufacturer put it 4 alarm at one register 16 bit. So 1-4 bit is High Oil Temperature, 5-8 High Coolant Temperature, 9-12 Low Oil Pressure, 13-16 Emergency Stop. And modbus device will return value from 0-15 depending on alarm condition. So I need to read 1-4 bit of register offset 2048. what formula it is I can use?
