C.29.2
Parameter-specific index method
Set Parameter Index Location (4.11.) (Page 270)= Parameter-specific.
The Parameter-specific index method sets the index values for each parameter
independently. Use this method to read multiple parameters with different index values.
1.
Write the primary index, secondary index, and data format values into the appropriate
format register.
For example, send the integer value 01008 to register 46,921, in order to read the
following information:
–
Measured level [Level (3.2.8.3.)] (Page 256)
–
In units with three decimal places
–
From Transducer 1
2.
Read the value from the appropriate parameter register (the example uses 44,921).
Types of values are:
●
Numeric values (Page 339)
●
Bit values (Page 339)
●
Split values (Page 341)
●
Text messages (Page 342)
●
Relay function codes (2.8.1.4. Relay function only) (Page 343)
A value of 22,222 indicates that an error occurred. Specify a different format type and try
again.
C.30
Writing parameters
The method of writing parameters is similar to the method of reading them. Become familiar
with Reading parameters (Page 334) before attempting to write any.
To write parameter values to the device, follow these steps:
C.30.1
Global index method
Set Parameter Index Location (4.11.) (Page 270) = *Global.
1.
Write the primary index value into R43,999.
2.
Write the secondary index value into R43,998.
3.
Write the desired format value into the appropriate format register.
4.
Write the value to the appropriate parameter register.
