Question: 2. A TRi T100M PLC is used as a temperature monitor. One of the A/D inputs, ADC(1), of the T100M is connected to the output

2. A TRi T100M PLC is used as a temperature monitor. One of the A/D inputs, ADC(1), of the T100M is connected to the output of a temperature sensor that outputs 0-5 volts dc for a 0-150 degree C temperature range. Assume the analog input of the T100M is unipolar, 5-volt, 12-bit resolution.

Write a PLC program that will continuously monitor the temperature and display it (in degrees C) in the LCD readout. Also, if the temperature is 50 degrees or more, turn on an output labeled ALARM. When the temperature falls below 50 degrees, turn off the ALARM output.

The format for the LCD display is Temp: xxx.x Deg. C

where xxx.x is the current temperature. Leading zero blanking is not necessary. For example, a temperature of 3.5 degrees could be displayed as Temp: 003.5 Deg. C

You are required to use only the single ALARM output assigned above. Do not use additional inputs or outputs. You may use as many internal relays as you wish. Timers are not required for this assignment - do not use them.
