Description
to confirm the control action.
If you configure the point to use electronic signatures, the server writes to the Dest
Address only after the correct entry of the password(s).
In Station, this value is read-only.
Only applicable if you use operator-based security.
The minimum control level (between 0 and 255) required to perform supervisory
control on this point. The default is 0.
The normal mode for this point, to which it is reset to after a command is issued.
The modes are:
AUTO (default). Automatic mode. The controller (or server) controls the
n
output and operators cannot change the output value.
MAN. Manual mode. The operator is permitted to change either the SP or
n
OP.
CASC. Cascade mode. Only applicable to S9000, TDC, and UDC con-
n
trollers. Used when the SP comes from the output of another PID loop
within the controller. When in CASC mode, operators cannot change either
the SP or OP.
COMP. Computer mode. Only applicable to a TDC controller. Used when
n
the SP comes from a computer that is performing automatic control. When
in COMP mode, operators can change either the SP or OP.
If selected, operators can parameter values regardless of point's mode.
If cleared, the server checks the mode before allowing an operator to change a
parameter value. (If the mode is set to AUTO, the operator is not allowed to
change the OP value.)
The highest value that can be set for the associated parameter. The value is
clamped at this value.
For OP, the value is specified as a percentage of the PV output range. The default
is 100%.
For SP, the value is specified in engineering units (EU).
The lowest value that can be set for the associated parameter. The value is
clamped at this value.
For OP, the value is specified as a percentage of the PV output range. The default
is 0%.
