Unused Step
This is an empty step that can be used to plan for future steps to be
inserted or temporarily deactivate a step in a profile. Change step type
back when the step should be active again.

Step Types
Time
If Ramping Type found in the Global Menu of the Setup Page is set
for Time, control loop 1 to 2 may be part of the profile and all enabled
control loops follow independent set points over the specified time. The
state of up to 2 event outputs may be set or maintained.

Rate
If Ramping Type found in the Global Menu of the Setup Page is set for
Rate, control loop 1 must be part of the profile and if control loop 2 is
enabled it must follow the same set point and rate in degrees or units
per minute. Ensure all control loops have the same units of measure.
The state of up to 2 event outputs may be set or maintained.

Wait For Time
A Wait for Time Step is available with the real-time calendar clock fea-
ture. This allows the program to wait for a specified day and time before
proceeding to the next step. Used to have the profile execute steps ev-
eryday or only weekdays. The state of up to 2 event outputs may be set
or maintained.

Step Types
Wait For Event
A Wait for Event Step will wait for the two Wait for Event states (1 to 2)
to match the specified state. The state of up to 2 event outputs may be
set or maintained.

Wait For Process
A Wait for Process Step will wait for Process Value 1 or 2 to match the
Wait for Process Value. The state of up to 2 event outputs may be set or
maintained.

Wait For Both
A Wait For Process and Event Step will wait for Process Value 1 or 2 to
match the Wait for Process 1 value, and/or the two Wait Event states to
match the specified state. The state of up to 2 event outputs may be set
or maintained.

Step Types
Jump Loop
A Jump Loop step will repeat previous steps a number of times des-
ignated in Jump Count. Jump Loops can be nested up to four deep.
The state of up to 2 event outputs may be set or maintained. This
step type not available in subroutine.

Step Types
End
An End Step will end the profile and set the control modes and set
points to match the End Type. The state of up to 2 event outputs may be
set or maintained. The event outputs will not be set off unless specifi-
cally stated in this step. If a profile does not have an End Step, the pro-
file continues until step 40, then stops and maintains the last set points
and control modes.
