Icon Name Description
Auto Switch to Auto from Manual. In auto, the
setpoint and ratio can be adjusted. If shaded,
switching to Auto is not allowed.
Manual Switch to Manual from Auto. In manual, the
output can be adjusted. If shaded, switching
to Manual is not allowed.
Computer Mode Request a switch to Computer mode.
Restricted parameters for PID loops are
SETPOINT, SPT_MODE, RESULT and
OUT_MODE. Restricted parameters for
Controller loops are RESULT and
OUT_MODE.
In Co
mputer Mode, you have two options;
LOCAL, where the operator is able to access
the restricted parameters but the computer
cannot, and COMPUTER, where the
computer program is allowed access to the
restricted parameters but the operator is not.
When the COMPUTER option is selected, the
operator can still change control to LOCAL.
Local Mode In Local Mode, the operator is able to access
the restricted parameters but the computer
cannot (see Computer Mode).
Remote Switch to remote setpoint. Remote setpoint
value is the result of another FCM. If shaded,
switching to Remote is not allowed.
Local Switch to local setpoint. Local setpoint value
comes from within the PID FCM. The operator
can change this value. If shaded, switching to
Local is not allowed.
