2.1 System operation

2.1.1Auto-RUN / Standby selection

The initial operation mode (HALT or RUN) just after power on is determined by the user-setting status of the Auto-RUN / Standby selection.

When the setting status is;

Auto-RUN: The T3H’s initial operation mode is determined by the mode control switch (HALT / RUN / P-RUN). When this switch is in RUN or P-RUN, the T3H moves into RUN mode automatically.

Standby: The T3H stays in HALT mode regardless of the mode control switch (HALT / RUN / P-RUN) after power on. Then the operation mode can be changed manually, i.e. by programmer command or by changing the mode control switch.

The Auto-RUN / Standby selection is included in the system information memory, and the selection is made by using the programmer.

NOTE

(1) The default setting is Standby.

 

(2)Different from the T3H, in case of the T3, this selection is made by the hardware switch (RAM/ROM switch).

2.1.2Timer interrupt interval

In the T3H, the timer interrupt program is available with the interval setting of 1 to 1000 ms in 1 ms increments.

(In case of the T3, it is 2 to 1000 ms in 1 ms increments)

NOTE

If you use the timer interrupt with 1 ms interval, consider to minimize the

 

 

execution time of the timer interrupt program. If the interrupt task requires

 

long time, the T3H cannot assign enough time for main program execution.

 

As the result, scan time over error will occur.

In case of the T3H, SFC (Sequential Function Chart) can also be programmed on the interrupt program, as well as Ladder diagram.
