Details

An example is provided to demonstrate scaling for the ADAM 6018 Module. The 6018 is an eight channel isolated thermocouple input Modbus TCP module. Two of the inputs are configured in this example. The input range for both of these thermocouples is 0 to 760 degrees Celsius. These are configure on channels 0 and 1 below.

InTouch ME reads the Modbus (Current) value. This is a 16-bit value decimal value ranging from 0 to 65,535. The decimal value is scaled to Celsius in InTouch ME as shown below.

Both of the decimal value inputs are divided by 86.230263. The raw range is 0 to 65,535 and the engineered range is 0 to 760. Divide the raw range by the engineered range to calculate the divisor as circled above.

65,535 - 0 / 720 - 0 = 86.230263

The temperature values in the HMI are then scaled to Celsius for the runtime display.
