5. Operation Mode Setting

5.1 Mode setting overview

The PI312 has total 9 operation modes.

(1) Quadrature bi-pulse counter mode

(2) Up/down pulse counter mode

(3) Auto-reset universal counter mode

(4) Universal counter mode

(5) Speed counter mode

(6) Programmable interval timer mode

(7) Gate-ON timer mode

(8) Slave counter mode

(9) Slave timer mode

As for above (1) through (7) modes, the operation mode can be set individually for

channel 1 and channel 2. For example, you can set channel 1 to the quadrature

bi-pulse counter and channel 2 to the speed counter.

On the other hand, when above (8) or (9) mode is used, channel 1 and channel 2

work relatively. In this case, channel 1 must be set to (3) auto-reset universal counter

mode. For example, when you use the slave counter mode, you should set channel 1

to the auto-reset universal counter and channel 2 to the slave counter.

To set the operation mode, jumper plugs and the operation mode register in the

PI312's buffer memory are used.

The jumper plugs are used to select either individual operation (above (1) through (7)

modes) or relative operation (above (8) and (9) modes).

There are 2 operation mode registers in the buffer memory. One is for channel 1 and

the other is for channel 2. By writing a mode data into this register, the operation

mode setting for each channel is established.
