Value Compare Function
The compare value function allows the comparison of an input value with predefined values in data registers.
This allows the activation of a low and high PGM output when the comparison is over the set point and the
hysterisis time.
FN001 Func Type
Value Compare
Use the [1] and [3] keys to scroll the function types until you reach the Value Compare selection and press
[ENTER] to select the function type displayed and proceed to the next programmable option for the Value
Compare function. For more information about the list control data entry refer to the section List Control Data
Entry (see page 335).
Function Mode
The function mode determines how this function operates with the system controller. By default a function is set
to normal operation. Normal operation will mean the function is started if it was running when the system
restarts or is completely powered down (AC Failure and Battery Failure). The Run Once mode of operation will
allow the function to run once and then wait to be stopped and started by the user or operator. Setting the run
once option for the value compare function will result in NO operation being performed and the function
stopping a short time after it is started.
FN001 Func Mode
Normal
Use the [1] and [3] keys to scroll the function mode until you reach the normal selection and press [ENTER] to
proceed to the next programmable option for the value compare function. For more information about the list
control data entry refer to the section List Control Data Entry (see page 335).
Enabled Control PGM
Enabled Control PGM is set when the value compare function is to run and will operate only when the enabled
PGM is on. If no enabled PGM is set the value compare function will run continuously. This allows the value
compare function to operate only during the times that the resulting PGM is required.
FN001 Enabled
pgm: --000:00
To modify the enabled PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336).
High PGM
The High PGM output will activate when the input data register (usually an input from an analog register) is
above the set point plus the hysterisis value and has been for the duration of the hysterisis time. The high PGM
will turn off if the input value is below the set point value.
FN001 High
pgm: --000:00
To modify the High PGM, use the settings as explained in section Entering PGM and PGM Groups (see page
336).
