Program Linking
Use this function to append program pattern 2 to program pattern 1 so the controller runs
according to the resulting single program pattern. You can also append program pattern 2
to program pattern 1.
Precautions when Linking Programs
There may be a case that a difference exists between the target setpoint defined for the
final segment of a program pattern to be run first and the starting target setpoint of a pro-
gram pattern to be combined with. If this is the case, a deviation may occur and therefore a
derivative action may take place, causing the control output to travel up to 100% or down to
0% and stay at this point.
If program linking is assumed, care must be taken to prevent any significant deviation from
arising between the setpoints to be linked when creating programs.

Setpoint of JC (Junction Code) Program Parameter
To append program pattern 2 to program pattern 1
Set the parameter Program Pattern-1 Junction Code (1.JC) to “3”.
To append program pattern 1 to program pattern 2
Set the parameter Program Pattern-2 Junction Code (2.JC) to “2”.

Retaining the End-of-Program State (End of Hold)
This function keeps the controller in the same state as when the program operation was
completed.
When in hold operation, the controller retains its states of control output and event output.
To cancel hold operation, use either key operation or external contact input. When the hold
operation is cancelled, the control output is set to 0% or OFF, and the event output is set to
OFF.
To retain the end-of-program state, set a Junction Code program parameter to “1”.
For example, if you want the controller to run according to program pattern 1 and retain the
same state as when the program ended, set the Program Pattern-1 Junction Code (1.JC)
parameter to “1”.
