Changing Over

Program functions can easily change over by reading out the judgment condition previously saved with the
input line. For details of program functions, refer to “Changeover for a Target (Program Functions)” (Page
6-8).

(1) Keeps the Program bit0 to bit4 input by switching to the state of the program number to be switched.

Minimum input time is 10 ms.

“When the [External IN] is selected in the Program Switch Method” (Page 6-11)

(2) The BUSY output turns ON while switching the programs. Switching time differs depending on the settings.
(3) The output status (Latching output and One-Shot output) turns OFF before the switching program is completed.
(4) If the program number is switched during the judgment process by the trigger input, the system cancels

the judgment process (result of Trigger 2 is not output). The switching process is delayed by the
canceling process. Delay is time differs depending on the settings.

(5) If the trigger occurs while switching the programs (during the BUSY output), the trigger is ignored and a

trigger error occurs. To output the trigger error, set the trigger error in the Output Assignment (Page 4-60)
under the Settings Navigator to [ON]. In the case of a manual trigger, the trigger is processed after the
switching program is completed.

For details on T1 and T2, refer to “Input Response Time” (Page 7-12).

y

Use this function during an operation. Programs cannot be switched with the external input during setup.

y

The trigger error output function turns OFF when the next trigger is activated, when the error is cleared,
when the program is switched, or when the system moves to the settings screen.

y

If the switched program is set to [Internal], the first timing for inputting the trigger after switching the
program fluctuates. A delay of one trigger interval may occur.

y

Do not use with the external master registration input at the same time. The sequence for switching
programs and external master registration process will vary.

y

The response of an image displayed on the monitor might be delayed until after switching programs (BUSY
output OFF).
