485 Trend 4 Operand Parameter X
[Tr4 Opnd Parm X]
Tr4 Opnd Parm X specifies the first of two parameter
numbers for the trend trigger evaluation. The data
value for the entered link parameter number is used
in the trigger evaluation.
Parameter Number 485
Parameter Type Read/Write, Sink
Display Units / Drive Units Dependent on Link➀
Factory Default 0
Minimum Value –32767➀
Maximum Value +32767➀
File – Group Diagnostics – Trend Setup
➀ These values depend on the source parameter that this parameter is linked to.
For example, if the source parameter’s drive units are rpm, then Tr4 Opnd Parm X’s
drive units will be displayed in rpm. The minimum and maximum values are also
link dependent.
486 Trend 4 Operand Parameter Y
[Tr4 Opnd Parm Y]
Tr4 Opnd Parm Y specifies the second of two
parameter numbers used for the trend trigger
evaluation. The data value for the entered link
parameter number is used in the trigger evaluation.
Parameter Number 486
Parameter Type Read/Write, Sink
Display Units / Drive Units Dependent on Link➀
Factory Default 0
Minimum Value –32767➀
Maximum Value +32767➀
File – Group Diagnostics – Trend Setup
➀ These values depend on the source parameter that this parameter is linked to.
For example, if the source parameter’s drive units are rpm, then Tr4 Opnd Parm Y’s
drive units will be displayed in rpm. The minimum and maximum values are also
link dependent.
487 Trend 4 Operator
[Tr4 Operator]
Tr4 Operator specifies the operator used for the
trend trigger evaluation. The available operators
are:
Value Description
1 Greater Than (.GT.)
2 Less Than (.LT.)
3 Equals (.EQ.)
4 Not Equals (.NE.)
5 Logical AND (.AND.)
6 Logical NAND (.NAND.)
7 Logical OR (.OR.)
8 Logical NOR (.NOR.)
Parameter Number 487
Parameter Type Read/Write, Non–Linkable Sink
Display Units / Drive Units None
Factory Default 5
Minimum Value 1
Maximum Value 8
File – Group Diagnostics – Trend Setup
488 Trend 4 Sample Rate
[Tr4 Sample Rate]
Tr4 Sample Rate specifies the interval at which the
data in the Trend In 4 parameter is sampled. It is
programmable in 2 millisecond increments. All
values are rounded down to the nearest 2
millisecond interval.
Parameter Number 488
Parameter Type Read/Write, Non–Linkable Sink
Display Units / Drive Units Seconds
Factory Default 0.020 Seconds
Minimum Value 0.002 Seconds
Maximum Value 30 Seconds
