Block Transfer Commands 17
Set Single Setpoint, All Values
Command: 319, 0x13F
Block Write: 10 words
Parameter: Setpoint number
Value: Values as required
Block Read: 2 words
Return Status: Batch
Return Value: None
Command 319 sets the target, hysteresis/bandwidth
and preact values for the specified setpoint in
floating-point format. This command is only valid if
the setpoint is enabled and requires a target value.
The structure of the block write command is as
follows:
Word 0: Command number
Word 1: Setpoint number
Word 2: Setpoint kind
Word 3: Reserved/not used
Words 4–5: Target value
Words 6–7: Hysteresis or band value
Words 8–9: Preact value
The value sent in words 6 and 7 is interpreted as
hysteresis or band value based on the TRIP setting of
the setpoint. If the setpoint requires neither a
hysteresis nor a band value, this value is ignored and
only the target value is set. The preact value is ignored
if preact is not enabled for the setpoint.
Table 4-6 lists the values specified for the setpoint
kind in word 2.
