TECHNICAL REFERENCE___________________________________________________________ SDI-12 Commands Table 22 below lists the available commands for operating WMT700 with SDI-12 profile. NOTE You can only use COM2 serial port for sending commands and receiving data messages with the SDI-12 profile. Table 22 Command ?! a! aI! aAb! aC! aCC! aD0! aM! aMC! aV! List of SDI-12 Commands Description Queries WMT700 for its address. Ensures that WMT700 is responding.
Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles ?! — Address Query This command queries for the WMT700 address. When you use a question mark (?) as the address character with the a! command, WMT700 responds as if it was being addressed on the SDI-12 bus. Regardless of its address, WMT700 responds to the command, which allows you to determine the address for the wind sensor.
TECHNICAL REFERENCE___________________________________________________________ a! — Acknowledge Active This command ensures that WMT700 is responding to a data recorder or another SDI-12 device. It asks the WMT700 to acknowledge its presence on the SDI-12 bus. a! where a = ! = The single-digit WMT700 address that corresponds to the first character of the address value. Terminates the command.
Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles aAb! — Change Address This command changes the WMT700 address. After WMT700 has received this command and sent a response, the sensor does not respond to any other command for one second. This gives WMT700 time to write the new address to the non-volatile memory. NOTE You can also change the WMT700 address by entering configuration mode and changing the address parameter.
TECHNICAL REFERENCE___________________________________________________________ The response is the following: atttnn where a = ttt = nn = = The single-digit WMT700 address that corresponds to the first character of the address value. The period of time, in seconds, after which WMT700 has the measurement ready. The number of measurement values WMT700 calculates and returns as a response to one or more subsequent aD0! commands. Terminates the response.
Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles aD0! where a = D0 ! = = The single-digit WMT700 address that corresponds to the first character of the address value. The send data command. Terminates the command. For a description of the data messages, see section SDI-12 Data Messages on page 70. aI! — Send Identification This command queries WMT700 for its SDI-12 compatibility level, model number, and firmware version number.
TECHNICAL REFERENCE___________________________________________________________ aM! — Start Measurement This command starts measurement. WMT700 does not return measurement data after this command. It sends a response that indicates when the measurement result can be retrieved using the aD0! command and the number of parameters. aM! where a = M ! = = The single-digit WMT700 address that corresponds to the first character of the address value. The start measurement command. Terminates the command.
Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles aV! — Start Verification This command starts verification. However, WMT700 does not return verification data directly after this command. It sends a response that specifies when the verification results can be retrieved using the aD0! command and the number of parameters. The WMT700 verification data includes a watchdog count, sensor measurement unit settings, and the current SDI mode setting.
TECHNICAL REFERENCE___________________________________________________________ SDI-12 Data Messages When SDI-12 profile is selected, the data message sent by WMT700 depends on the command that you use before fetching the data with aD0! command.
Chapter 5 ______________________________ Operating WMT700 with WS425 and SDI-12 profiles WS425 A/B SDI-12 Message for V Command When you have given the commands aV! and aD0!, the response is the following: a where a = = The single-digit WMT700 address that corresponds to the first character of the address value.
