For example: When using Point Indexing the configuration of:
Specifies four Registers (100, 101, 102, and 104) that are mapped to
a group of Analog Input (AIN) values in engineering units (EU)
starting at the Analog Input in the forth module location, first position
(4-1).
• Register 100 - EU of AIN point in location 4-1
• Register 101 - EU of AIN point in location 4-2
• Register 102 - EU of AIN point in location 4-3
• Register 103 - EU of AIN point in location 4-4
For example: When using Parameter Indexing the configuration of:
Specifies three Registers (7100, 7101, and 7102) that are mapped to
a group of AGA parameters starting at CUR DP.
• Register 7100 - CUR DP (hw - differential pressure)
• Register 7101 - CUR SP (Pf - static pressure)
• Register 7102 - CUR TP (Tf - temperature)
7. Select the type of Indexing to define the block of Register values for
the Point Types or the Parameters without having to define each
separately.
• Select Point to define the Register values as Point Types. If
multiple Registers are used (Starting and Ending Register values
are different), each successive Register increments to the next
logical point number of the same Point Type.
• Select Param to define the Register values as Parameters. If
multiple Registers are used (Starting and Ending Register values
are different), each successive Register increments to the next
logical Parameter of the Point Types to be set or acquire data. Be
aware of the different data types (Character, Integer, Long, Float)
and the size of the data types. Use the TLP button to select
parameters.
8. Specify the type of Conversion required, if any, on the data before it is
sent to the host or written to the 3095FC. The conversions are used
to allow integer values to be transmitted and received instead of
floating point values. Table 3-8 lists the Convert Codes used with the
Modbus Protocol Emulation program. Conversion codes affect
Function Codes 3, 4, 6, 8, and 16.
