CR10X processing for MicroMet

Version 1.03 and above

The CR10X, when used with the MicroMet MBTU10X for data transport, must be

programmed specifically with the MBTU10X in mind. The CR10X must:

1. Output a data message to its serial port at 1200 baud. The data message format

must be as follows: 444,JJJ,HHMM,s1,s2…snCRLF

2. Data points must be integer values in the range of 0 to 4095. Any non-integer

values are truncated by MBTU10X to integer size (40.99 becomes 40). Any values

less than zero (0) become zero (0). Values larger than 4095 become 4095.

The process in the CR10X looks like this:

! Assign the data storage ID of 444.

! Every few seconds:

1. Read the sensors.

! Every hour:

1. Calculate and save the hourly summary values to input locations.

2. Scale the input locations for transport (0-4095) and output them to the serial port.

(Also saved to output locations.)

3. Output a CRLF sequence to the serial port.

! Every day (midnite):

1. Calculate and save the daily summary to input locations.

Things to consider when modifying a CR10X program for MicroMet:

! Sensors

! Sensor input labels. Edit these with PC208W so they match what sensors you

actually have.

! Transport scaling.

! Number of sensors output from scaling input area.

! Scaling input labels. (vB12, iSWT, iPst,…) These must be in order delivered to

master station.
