I am a beginner to Mitsubishi PLC and use a high speed counter C235 to record pulse signals

The number of numerators can be registered.

d, for example, out c235 d0, and then use the screen to enter the value of d1d0. Because C235 is a 32-bit counter.

Therefore, the setpoint should also be 32 bits, that is, 2 consecutive ds.

There are also C235 and C236 count values are hardware, the corresponding X is determined, not in the program.

A brief overview of the Mitsubishi PLCFX3UC high-speed counter (C235 C255).

The FX3UC high-speed counter is only compatible with the basic unit of the DC input type. High-speed counters, either with a universal input terminal for the incoming base unit, or with a special adapter for high-speed input.

option products).

The difference between the two products is the highest frequency that can be counted and the kind of input signal.

Universal input terminal for the base unit.

The signal output of an open-collector transistor can be input, and a maximum of 100kHz (single-phase) can be counted.

Special adapter for high-speed input.

It is possible to input a signal with a differential output, and a maximum of 200kHz (single phase) can be counted.

Points to note when using a special adapter for high-speed input.

Please select one of the high-speed input special adapters or the same input number of the base unit.

When wiring on the input number assigned to the high-speed input special adapter, do not wire on the input terminal of the same number of the base unit.

When wiring is not on the input number assigned to the high-speed input special adapter, the input terminal of the same number of the base unit can be used as a universal input. First of all, the 10,000 pulses you send must be partly used for acceleration, partly for constant speed, and partly for deceleration, otherwise you can't stop at high speed, and you will definitely go more.

In addition, the value of the count can be read out of c235. The key is to control when to count and reset.

Yes, your understanding is quite correct. In Mitsubishi PLC, there are only 6 points (x0---x5) at the input end of the high-speed hail hole counting device, and if one of them is occupied by the wanton, it can no longer be used for other high-speed counters or other purposes, so only 6 high-speed counters can work at the same time.

A normal counter can use any logic such as x, m, y, etc. to tease a single-chain shroud.

In the high-speed bumping counter, C235 --C240 corresponds to x0---x5

No, you don't. The C235 high-speed counter is used with X0.

Mitsubishi PLC, high-speed counter C235, will not automatically reset when not turned on, must RST command reset.

Mitsubishi PLC C235 is originally a high-speed counter, if you turn a few times in 5 seconds, it is no problem, if you turn two or three times in 1 second in the scum line, then you have to divide the frequency.

Yes, otherwise the speed will not be able to keep up, and there will be counting errors.

After using C254, X0, X1, X2, X6 are automatically occupied, and if it is used in elevators, there must be a pulse source connected to these ports, such as a rotary encoder, which can be used as a floor sensor.

Mitsubishi High Speed Reversible Counter C235-C255. C235-C245 is single-phase single-input, C246-C250 is single-phase dual-input, C251-C255 is dual-phase dual-input, they have different functions.

To be compiled in PLC C235 accounting number.

Yes, your understanding is quite correct. In Mitsubishi PLC, there are only 6 points (x0---x5) at the input end of the high-speed counter, and if one of them is occupied, it cannot be used for other high-speed counters or other purposes, so only 6 high-speed counters can work at the same time.
