Installation, Operation and Maintainance of Automatic Meteorological Stations

Annex 3.2: METSTAT Datalogger Program

METSTAT is a data logger program for the CR10X Control and Storage Module, intended for the Meteorological Sta-

tions established by the Lake Victoria Water Resources and Nile Basin Water Resources Projects. This program is

based on the Structure Diagram presented in Annex 3.1.

The program is created in EDLOG and stored in the files “METSTAT.CSI” and “METSTAT.DLD” respectively. The

latter concerns the compiled version.

;DATA LOGGER PROGRAM FOR METEOROLOGICAL STATIONS IMPLEMENTED BY GCP/RAF/304/JPN AND GCP/

INT/752/ITA PROJECTS IN THE NILE BASIN REGION

;CREATED BY BART HILHORST, 19 JANUARY 1998

;FINAL MODIFIED VERSION CREATED BY BART HILHORST, 20 MARCH 1998

;WIRING SCHEDULE HAS BEEN DETERMINED BY SHORTCUT

;NO USE IS MADE OF FINAL STORAGE AREA 2 IN ORDER TO FACILITATE AUTOMATIC

;DOWN LOADING OF DATA UPON CONNECTION OF SM192 OR SM4M TO CR10X

;TO THIS END, DUE TO THE EXECUTION INTERVAL OF 300 SEC, THE SM192/SM4M HAS TO

;STAY CONNECTED TO THE CR10X FOR AT LEAST 10 MINUTES

*Table 1 Program

01: 300 Execution Interval (seconds)

;==================== PART 0, DATALOGGER ID ===================

1: If time is (P92)

1: 0 Minutes (Seconds --) into a

2: 1440 Interval (same units as above)

3: 30 Then Do

2: Read ID (P117)

1: 24 Loc [ LOGGER_ID ]

3: End (P95)

;DETERMINE DATALOGGER-ID IN ORDER TO DISTINGUISH STATION IN CASE

;SEVERAL STATIONS ARE VISITED DURING THE SAME INSPECTION TRIP

;======================= END OF PART 0 ==========================

;====================== PART 1, MEASUREMENTS ====================

;PART 1: MEASUREMENTS, ALL SIX SENSORS ARE MEASURED EVERY 5 MINUTES

;IN ORDER TO REDUCE POWER CONSUMPTION, CS500 IS ONLY SWITCHED ON

;DURING MEASUREMENT, DIRECTLY AFTERWARDS, IT IS SWITCHED OFF

;SWITCH ON CS500 (AIR TEMP AND RH SENSORS)
