Function Code 51- Manual Set Constant
GENERAL DESCRIPTION
The output of the Manual Set Constant or the Signal Generator is an analog signal
developed within the function that is equal to . This function provides a tunable
output value in engineering units.
UTILIZATION
The MOD 30ML/MODCELL compound FC51 used here has a function block namely
the Expression block.
Figure 51 .1.
FC51 Compound
The Expression block used in this compound has one input named S1 configured as a
floating point. The result of the expression is configured as S1. The data type of the result
is configured as floating point.
This block also allows selection of the data type for the manual set constant compared to
only the analog type in the Bailey Function code 51. There are 10 allowed data types for
the expression block inputs. They are:
Data Type Allowed Values
Discrete 0 or 1
Short State 0 - 15
Long State 0 - 255
Count 0 - 65535
Date Year (0 – 99), Month (0 – 12), Day (0 – 31)
Floating Point IEEE Single precision floating point
Millisecond time Format: hh:mm:ss.xxx (xxx in millisecond)
Hex Hexadecimal
Momentary discrete 0 or 1
ASCII ASCII Characters/String
