Toshiba PROSEC T3H Manual De Usuario

PROSEC T3H 

 

 
 

 

 
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. 
 
 

 
 

 

 

 

 
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) 
 
 

 
 
 

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

NOTE

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).  

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.
