Chapter 3: Controller Parameter Descriptions

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).
