Low-Frequency Pulse Generator
There are 4 low-frequency pulse timers in the system
Software PLC control
Address | Variable Name | Description |
---|---|---|
0x10000AB | EXT_MYTIMER_SET | Set up, enable/disable pulse generator |
0x10000AC | EXT_MYTIMER_SET_PULSE | Set pulse time (in milliseconds) |
0x10000AD | EXT_MYTIMER_SET_PAUSE | Set pause time (in milliseconds) |
Pulse generator set up
Writing to the Software PLC register number 0x10000AB is used to set up Pulse generator.
- Byte 0 of written value is the OUT port number for the pulse generator
- Byte 2 - set the current state of the pulse generator. Bit #1 is to enable/disable the generator.
- 0 - timer DISABLED
- 2 - timer ENABLED
- Byte 3 - timer number.
Software PLC example: set up and turn the generator ON
- PULSES_ON.plc
#define port_num 8 #define t_pulse 200 #define t_pause 800 main() { gvarset(0x10000ac,t_pulse); gvarset(0x10000ad,t_pause); x=port_num|(2<<16); gvarset(0x10000ab,x); exit(99); };
Software PLC example: set up and turn the generator OFF
- PULSES_OFF.plc
#define port_num 8 main() { gvarset(0x10000ab,port_num); exit(99); };
Hardware PLC control
Address | Variable Name | Description |

8100 | GVAR_TIMER0_ENABLED | 0 - DISABLE; 1- ENABLE |
8101 | GVAR_TIMER0_PORT | Set Output pin number for timer/generator 0 |
8102 | GVAR_TIMER0_PULSE | Set pulse time in milliseconds for timer/generator 0 |
8103 | GVAR_TIMER0_PAUSE | Set pause time in milliseconds for timer/generator 0 |
8104 | GVAR_TIMER1_ENABLED | 0 - DISABLE; 1- ENABLE |
8105 | GVAR_TIMER1_PORT | Set Output pin number for timer/generator 1 |
8106 | GVAR_TIMER1_PULSE | Set pulse time in milliseconds for timer/generator 1 |
8107 | GVAR_TIMER1_PAUSE | Set pause time in milliseconds for timer/generator 1 |
8108 | GVAR_TIMER2_ENABLED | 0 - DISABLE; 1- ENABLE |
8109 | GVAR_TIMER2_PORT | Set Output pin number for timer/generator 2 |
8110 | GVAR_TIMER2_PULSE | Set pulse time in milliseconds for timer/generator 2 |
8111 | GVAR_TIMER2_PAUSE | Set pause time in milliseconds for timer/generator 2 |
8112 | GVAR_TIMER3_ENABLED | 0 - DISABLE; 1- ENABLE |
8113 | GVAR_TIMER3_PORT | Set Output pin number for timer/generator 3 |
8114 | GVAR_TIMER3_PULSE | Set pulse time in milliseconds for timer/generator 3 |
8115 | GVAR_TIMER3_PAUSE | Set pause time in milliseconds for timer/generator 3 |
Hardware PLC example: set up and turn the generator ON
- M07.plc
#define port_num 8 #define t_pulse 200 #define t_pause 800 main() { gvarset(8100,1); gvarset(8101,port_num); gvarset(8102,t_pulse); gvarset(8103,t_pause); exit(99); };
