Communications Specification 63

Default: 19.

Number of Cycles (52)

This parameter represents the total number of times to repeat the current
profile. Users can set 1 to 99 repeat cycle profiles or they can set the
profile to cycle continuously.

Range: 0 (continuous), 1 to 99.

Default: 1.

Ready Setpoint (53)

This parameter represents the ready segment’s setpoint. The first
segment begins ramping from the ready segment setpoint. When the
profile ends, the process returns to this setpoint. (This value is affected
by precision.)

Range: Low Process Variable to high Process Variable. (–999 to

9999, legal value determined by input type.)

Default: 0.

Special logic applies to determining the decimal placement for the
Ready Setpoint when using the Anafaze/AB protocol. When a profile is
assigned to a loop and the precision of the loop is greater than or equal
to 0, the setpoint is divided by an additional factor of 10 when the
precision is applied. When the profile is assigned to a loop with
precision –1, the precision is applied to the setpoint as usual (see
Precision (19) on page 53).

For example, if a profile with a Ready Setpoint of 1000 is assigned to a
loop with its Input Type set to Linear and its Precision to 1, the resulting
setpoint is 10. If the same profile were assigned to a loop with Input
Type set to J-type thermocouple (precision set to –1), the setpoint would
be 100.

For the Modbus-RTU protocol, the setpoint is scaled by the precision
setting only.

Ready Event States (54)

This parameter describes the ready segment’s output state for all outputs
that are not used for control or for the SDAC clock. When the loop goes
to the ready state, these outputs assume the state specified by this
parameter.

Range: 0 (off) or 1 (on).

Default: 0 (off).
