If the Trip bit is set, a Latch Off operation is performed, and if the Close bit is set, a Latch On
operation is performed on the specified index. The Status field is used exactly as defined. All
other fields are ignored. A pulse operation asserts a point for a single processing interval.
Caution should be exercised with multiple remote bit pulses in a single message (i.e., point count
> 1), as this may result in some of the pulse commands being ignored and returning an already
active status.
Analog Outputs (objects 40 and 41) are supported as defined by the preceding table. Flags
returned with object 40 responses are always set to 0. The Control Status field of object 41
requests is ignored. If the value written to index 0 is outside of the range 1 through 6, the relay
will not accept the value and will return a hardware error status.
