Configuring the CX1000/CX2000
Ratio (Remote)
Turns ON when a given ratio is applied to SP.
When turned ON, set the ratio in the range from 0.0001–30000. Set the decimal place in
the range from 0 to 4.
Remote Bias
You can select ON or OFF to determine whether bias is applied to SP.
When turned ON, set the bias value in the PV range of “EUS( -100% to 100%).”
Math Error
If a computation error occurs, specify whether to process it as a PV/SP, overrange, or
underrange.
Constants
Set the constants to be used for PV/SP computation, analog retransmission, and logic
computation. Constants are common for analog retransmission and logic computation.
Analog Retransmission
Sets the equation and output span on loops whose control mode is analog
retransmission.
Mode
Select ON or OFF.
ON: Activates the equation.
OFF: Analog retransmission does not function.
Equation
Enter the analog retransmission equation.
Output Span
Set the maximum value, minimum value, decimal place (0–4), and units using 6
alphanumeric characters or less.
Set the max. and min. values between -30000 and 30000 such that max. > min., and
max. - min. ≤ 30000.
Math Error
Select whether to set to an overrange or underrange when computed results in an error.
Constants
Set the constants to be used for PV/SP computation, analog retransmission, and logic
computation.
