Global Index Method - Siemens HydroRanger 200 HMI Operating Instructions Manual

C.29.1

Global index method

Set Parameter Index Location (4.11.) (Page 270) = Global.
Global format method sets index values for all parameters simultaneously. Use this method
to read multiple values set to the same index values.
1. Write the primary index value into R43,999.
This is a value between 0 and 40 which specifies the input or output indexed by the
parameter.
Examples are:
– Transducer 1 is Index 1.
– Discrete input 2 is Index 2.
– Relay 5 is Index 5.
2. Write the secondary index value into R43,998.
This is a value between 0 and 40 that specifies the secondary index on the parameter.
This value is usually 0.
3. Write the desired format value into the appropriate format register. Because the primary
and secondary indexes are already specified, these portions of the format word are
ignored and only the last digit is significant.
See Format register (Page 348).
4. Read the value from the appropriate parameter register.
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 has occurred. Specify a different format type and try
again.
