Proprieties: Sys, CFG
Description:
They define the relay output control origin.
Internal Use:
it is used according to selected operation mode (P202). It indicates that for this operation mode
the digital output has a predefined function.
Ladder:
it is used by the user program implemented in Ladder.
Fieldbus:
it is used directly by the industrial network master.
Alarm/Fault (NO) Signal:
it is used to signal alarm or fault. In case of alarm or fault the output is closed,
remaining like this until the cause of failure is not present anymore and the reset control is set.
Trip/Error (NO) Signal:
it is used to signal Trip or error. In case of Trip or error (Ex. No communication with the
Current Measuring Unit) the output is closed, remaining this until the cause of the failure is not present anymore
and the reset control is set.
Trip/Error (NC) Signal:
it is used to signal Trip or error. In case of Trip or error (Ex. No communication with
the Current Measuring Unit) the output is closed, remaining like this until the cause of the failure is not present
anymore and the reset control is set.
Check Back (NO) Signal:
is used to indicate the check back signal state, according to the selection of the
check back type (P208) and configuration of the operating mode (P202). If the check back type is configured for
motor current (P208 = 0), the digital output is activated as soon as the reading of the motor current is identified.
If P208 = 1, the digital output is activated whenever the digital input defined to be the check back signal is
activated. For P208 = 2, the digital output is activated whenever the output(s) configured for internal use is
activated.
Option 7 to 26:
are used to signal Trip for a specific protection; in case of Trip, the output is closed, remaining
like this until the cause of the failure is not present anymore and the control is reset.
