14 HIGH-SPEED COUNTER INSTRUCTION
14.1 High-speed Processing Instruction
*1 When high-speed counter (function number: K0) is stopped during function operation, the function continues to operate, but nothing will
be processed.
*2 When multi-output high-speed comparison table (function number: K30) is stopped, high-speed counter of the same ch is also stopped.
The following table shows the values which can be specified in (s2) and (s3) for each function number.
• Function number K0
The counting start and stop of a high-speed counter can be controlled for each channel of the high-speed counter.
CH1 to CH8 are for the CPU module, and CH9 to CH16 are for the high-speed pulse input/output module.
Ex.
To start CH3, set 04H in (s2). To stop it, set 04H in (s3).
To start CH1, CH4, and CH5, set 19H in (s2). To stop them, set 19H in (s3).
To start CH1 and CH4 and to stop CH5, set 09H in (s2) and set 10H in (s3).
• Function number K10
The measuring start and stop of the pulse density (rotation speed measurement) can be controlled for each channel of the
high-speed counter.
• Function number K20 to K24
Set the value to turn on the bit of the high-speed comparison table number which is to be started or stopped.
In the case of the CPU module (K20), b0 to b31 can be used.
In the case of the high-speed pulse input/output module (K21 to K24), b0 to b14 can be used.
• Function number K30
For the multi-output high-speed comparison table, specification of a channel is not required. To start the multi-output high-
speed comparison table, set 01H in (s2). To stop it, set 01H in (s3).
• Function numbers K40 and K50
The measuring start and stop of pulse width measurement and PWM can be controlled for each channel.
CH1 to CH4 are for the CPU module, and CH5 to CH12 are for the high-speed pulse input/output module.
