How to include position of circuit breaker into the relay logic?
For this, you will have to assign the circuit breaker of interest inside of the relay logic block (RelLogdip). Status of each assigned circuit breaker can be accessed by defining "_SWTx" Input Signal. "x" represents the index of the circuit breaker position inside of RelLogdip.
In the attached example, there is a relay R1 with two settings, Settings 1 and Settings 2. Graphically, these settings are represented by means of two relays named, R1_Settings1 and R1_Settings2. The activation of the settings depends on the position of the circuit breaker. Both of them are getting measured current from the same current transformer. The relay will trip if the measured current is higher then the pickup current and if the corresponding circuit breaker is closed (breaker "SxDown").
