Command HART command to be sent to the HART equipment. The effective
value of each HART command is as follows:
•Read Unique Identifier: 0
•Read Primary Variable:1
•Read P. V. Current And Percent Of Range: 2
•Read Dynamic Variable And P. V. Current: 3
•Read Transmitter Variables: 15
•Read Primary Variable Output Information: 33
•Reset Configuration Changed Flag: 38
•Read additional Transmitter Status: 48
•Read Transmitter Variable Information: 54
Scan Time Time cycle of scanning HART equipment data.
Effective range is 50 ms…50 hours.
Send Register Register for storing command data.
Effective range is 40003…49999 for 1758-RTU controllers and
40003…47999 for 1758-FLO controllers.
Return Register Register for storing command response data.
Effective range is 40003…49999 for 1758-RTU controllers and
40003…47999 for 1758-FLO controllers.
Unit Register Register for storing the unit of HART equipment data returned.
Effective range is 40003…49999 for 1758-RTU controllers and
40003…47999 for 1758-FLO controllers.
HART State Addr Register for storing HART equipment state returned.
Effective range is 40003…49999 for 1758-RTU controllers and
40003…47999 for 1758-FLO controllers.
Err_Cnt Number of times an error occurs.
After the HART scan block is configured, if there is no connection
with the slave device or if communication fails, this value will be
incremented by 1 after each scan cycle. This value is updated
whenever Upload is clicked.
Err_State Error state of HART scan block configuration.
If the Err_State value is 1, it means the communication has failed.
A value of 0 indicates that the communication is OK.
IMPORTANT
HART scan data blocks are configured in sequence and
each block has a corresponding number. The maximum
number of modules is 128.
When one data block is an empty block, all the blocks
configured after this empty data block will be invalid.
