Input Signal Lo
For linear inputs (see Setting up User Selectable Linear Inputs
on page 98), enter the sensor signal level that corresponds to
the low process value entered in PV Lo (see below). The input
Signal Lo is entered in the units of the Input Type.
Range: Depends on Input Type selected. See Table 3.15 on page
130.
Input Signal Hi
For linear inputs (see Setting up User Selectable Linear Inputs
on page 98), enter the sensor signal level that corresponds to
the high process value entered in PV Hi (see below). The Input
Signal Hi is entered in the units of the Input Type selected.
Range: Depends on Input Type selected. See Table 3.15 on page
130.
PV Lo
For linear inputs (see Setting up User Selectable Linear Inputs
on page 98), enter a low process value. Set this parameter to the
value to be displayed when the signal is at the level set in Input
Signal Lo (see above). The Input Value (PV) will not indicate a
value less than the PV Lo regardless of how low the sensor
signal dives. The set point and alarm limits for an associated
channel cannot be set to values less than PV Lo.
Range: Depends on Decimal Places. See Table 3.4 on page 100.
PV Hi
For linear inputs (see Setting up User Selectable Linear Inputs
on page 98), enter a high process value. Set this parameter to
the value to be displayed when the signal is at the level set in
Input Signal Hi (see above). The Input Value (PV) will not indicate a
value greater than the PV Hi regardless of how low the sensor
signal rises. The set point and alarm limits for an associated
channel cannot be set to values higher than PV Hi.
Range: Depends on Decimal Places. See Table 3.4 on page 100.
Digital I/O
Parameters on the Dig I/O spreadsheet determine the state and
behavior of digital or discrete inputs and outputs found on the
PPC’s processor and digital I/O modules.
