The setpoint is disabled when its trigger parameter is set to NONE. To disable the setpoint,
write zero into this register.
When writing the setpoint registers (except the event when the setpoint is to be disabled), it is
recommended to write all the setpoint registers using a single request, or disable the setpoint
before writing into separate registers. Each value being written is checked for compatibility with
the other setpoint parameters; if the new value does not conform to these, the request will be
rejected.
Operate and release limits for the trigger parameters and their conversion scales are indicated
in Table 5-18. Each limit value occupies two contiguous registers, the first of which (low word)
contains the limit value, and the second (high word) is reserved for long parameters. This
register is always read as zero. When written, its value is ignored.
Limits indicated in Table 5-18 by a N/A mark are read as zeros. When writing, they can be
omitted or should be written as zeros.
When a setpoint action is directed to a relay allocated to output energy pulses, an attempt to re-
allocate it for a setpoint will result in a negative response.
