duration of the hysterisis time. The low PGM will turn off if the input value is above the set
point value.
FN001 Low
pgm: --000:00
To modify the low PGM, use the settings as explained in section Entering PGM and PGM
Groups on Page 410.
Base Data Register
The Base data register is used as the first register in the list of registers used to configure,
program and control the Value Compare. The only registers that are not included in the base
registers are ones that must link to an analog input or analog output for external sensors
(Temp, Daylight (LUX), Water Level). A base data register setting MUST be set to ensure the
system can pick up the set points and data values.
FN001 Base data
reg: 00000
To modify the base data register (00000 to 65535, use the keypad as explained in section
Entering Decimal Numbers on Page 405 and press [ENTER].
Base Data Register Offset
Register Offset Register Function
0 Input Value Set Point
The input value set point is used to determine at what point the
comparison input register value used in the calculation is high or
low. The Input Hysterisis value is added or subtracted from the set
point to prevent an oscillation on the output PGM's.
1 Input Hysterisis Value
The hysterisis value that the comparison input must be above or
below the setpoint to activate the low or high PGM outputs. This
value is added to the input value or subtracted dependent on the
direction the comparison input is changing.
2 Input Hysterisis Time
The time that the value must be above or below the set point to
proceed with activating the low and high PGM outputs. This setting
is the number of seconds the value must be above or below.
Using the register configuration settings above and the following data values in the
configuration registers the following will be observed. The comparison input register in this
example is linked to the first channel on the Analog Expander. This was tested using a linear
variable resistor with a 10V supply reference that can be connected to the input to allow
manual control using the knob on the variable resistor.
Programmed Settings
Base Register is 00100
Value Data Register is 00000 (First Analog Input Channel on AE001)
