PV Range (PV or PV1)
Set the maximum value, minimum value, decimal point position (0 to 4), and unit (up to 6
alphanumeric characters).
Set the maximum and minimum values between –30000 and 30000. The maximum
value must be greater than the minimum value and the difference between the two must
be less than or equal to 30000.
You can set PV1 even when the mode is OFF.
PV Switch (PV1)
Set the values within the PV range. Set the decimal point position (0 to 4), upper limit (U),
and lower limit (L). If [Method] is set to [TCRange] in the [Control Setting] of the [Internal
loop] item under the [Setup] tab, set the upper limit (U) and lower limit (L). If [Method]
is set to [PVHigh], set only the upper limit. If [Method] is set to [Signal], the PV Switch
setting is not available.
You can set this item even when the mode is OFF.
Ratio (Remote)
Turn this ON when applying a given ratio to the SP.
When it is ON, set the ratio between 0.0001 and 30000. Set the decimal point position in
the range of 0 to 4.
Remote bias
Turn ON/OFF the use of the bias on the SP.
When it is ON, set the bias value in the EUS (–100% to 100%) range of PV Range.
Math Error
Set whether to handle the PV/SP as overrange or underrange when a computation error
occurs.
Constant
Set the constants used for PV/SP math, retransmission, and logic math. The constants
are common with the constants of retransmission and logic math.
Retransmsson
Set the expression or output span on loops whose control mode is set to retransmission.
Mode
Select ON or OFF.
ON: Enables the expression.
OFF: Disables retransmission.
