SBO rejected Error

SBO rejected Error

Hello Team,
While trying to execute a breaker operation from Zenon I get a interlock text 'SBO rejected'. I had referred to the help in Zenon but could not arrive at a reason/solution. Whether it is a internal interlocking text from IED or is it from Zenon?

Please suggest what could be a possible reason for this.

Thank You
