Command 2:Read Primary Variable's Current And Percentage Value; Command 3:Read Primary Variable Current And Dynamic Variables - Bell VFM60 Series User Introduction Manual

Remark:The unit code is 75:kg/hour, 19:m3/hour.
Set primary command to flow rate.
Test of command:
Send command 1: FF FF FF FF FF 82 9A 1A AD 18 8C 01 00 3A ;to read the IEEE754 float
value of primary variable.
Receive command 1:FF FF FF FF FF 86 9A 1A AD 18 8C 01 07 00 00 13 00 00 00 00 2A

7.1.3 Command 2:Read primary variable's current and percentage value

Command formate:
Read the current and percent of the primary variable, the current of primary variable always match
the AO current output of the instrument. Percent is not restricted within 0~100%, if it is beyond the
limit of primary variable, it will find the limit fo the transmitter.
Request: None
Reponse:
Byte 0-3:
Byte 4-7:
Test of command:
Send command 2:FF FF FF FF FF 82 9A 1A AD 18 8C 02 00 39 ; to read the current and
primary variable percent of range.
Receive command 2:FF FF FF FF FF 86 9A 1A AD 18 8C 02 0A 00 00 40 80 00 00 00 00 00 00

7.1.4 Command 3:Read primary variable current and dynamic variables

Command formate:
Read the current of primary variable and 4 preset dynamic variables at maximum. The current of
primary variable always match the AO output current of the instrument. Every type of device has a
definition on a relative dynamic variable, for example the secondary variable is temperature sensor.
Request: None
Response:
Byte 0-3:

Byte 5-8:
Byte 9:
Byte 10-13: Secondary variable, IEEE 754
Byte 14:
Byte 15-18: Tertiary variable, IEEE 754
Byte 19:
Byte 20-23:
Remark:Primary variable is flow rate. The unit code is 75:kg/hour, 19:m3/hour;
Secondary variable is total flow. The unit code is 61:kg, 43:m3;
