Section 11. Programming Resource Library Mv! SDIRecorder () Instruction SDICommand Entry Actions Internal to CR200(X) and Sensor CR200(X): Issues aMv! command Sensor: Responds with atttnn CR200(X): Waits until ttt 1 seconds. Issues aDv! command(s) Sensor: Responds with data. Cv! CR200(X): Issues aCv! command Sensor: Responds with atttnn CR200(X): If ttt=0 then issues aDv! command(s) Sensor: Responds with data. CR200(X): else, if ttt>0 then moves to next CRBASIC program instruction. CR200(X): At next time SDIRecorder() is executed, if elapsed time < ttt, moves to next CRBASIC instruction,. CR200(X): else, issues aDv! command(s) Sensor: Responds with data. CR200(X): Issues aCv! command (to request data for next scan). Cv (note: no ! termination) CR200(X): Tests to see if ttt expired. If ttt not expired, loads "1e9" into first variable then moves to next CRBASIC instruction. If ttt expired, issues aDv! command(s). Sensor: Responds to aDv! command(s) with data, if any. If no data, loads NAN into variable. CR200(X): moves to next CRBASIC instruction (does not re-issue aCv! command). 1 Note that ttt is local only to the SDIRecorder() instruction. 11.4.3 SDI-12 Power Considerations When a command is sent by the datalogger to an SDI-12 probe, all probes on the same SDI-12 port will wake up. Only the probe addressed by the datalogger 118
Section 11. Programming Resource Library will respond, however, all other probes will remain active until the timeout period expires. Example: Probe: Water Content Power Usage: • Quiescent: 0.25 mA • Measurement: 120 mA • Measurement Time: 15 s • Active: 66 mA • Timeout: 15 s Probes 1, 2, 3, and 4 are connected to SDI-12 / Control Port 1. The time line in TABLE. Example Power Usage Profile for a Network of SDI-12 Probes (p. 119) shows a 35 second power usage profile example. Table 15.
