I/O module question with M91

[Guest kostya_v]

Good afternoon. At me such question. At connection to M91-2-R2C IO-DI8-RO4 unit it is impossible to configure the high speed counter. It is impossible to appropriate I32 as the given counter.

We use U90Ladder v.6.1.7. On help it was possible to make it.

As there is a problem with downloading of prior versions U90Ladder. They any cut off, all on 48,15 Mb

I just checked this and it seems to work proerly:

Make sure you click on the Type field and not the Description.

[Guest kostya_v]

You haven't understood, I not can select the address on which there will be to go an exterior signal.

In help the same adjustments look in another way

where in the Help do you see this?

[Guest kostya_v]

Excuse, I was mistaken, this manual from Visilogic. Unless it is impossible in M91 to assign on the additional unit an output for the counter?

[Guest kostya_v]

There can be it depends on the software version? But old versions are downloaded, but not put, and not unpacked.

Unless it is impossible in M91 to assign on the additional unit an output for the counter?

Can yo explain what do you mean? Maybe you can explain in Russian?

Возможно ли в M91-2-R2C с модулем расширения IO-DI8-RO4 в модуле расширения включить счетчик (HSI) и считывать информацию с входа, например, с I32. Может использование этой функции зависит от версии программы? Старые, скаченные с сайта, не получается установить, они не до конца выложены.

Hi Kostya,

As you can see in the attached capture, you can define one high speed counter in IO-DI8-RO4. In attached spec you can see (bottom of page 6) that this is I7 of the local module (see hardware configuration for the real address in the system)and the max frequency is up to 5 kHz.

Note: HSC is supported only by I7 of the module! There is only one HSI in this module.

In hardware configuration of the project you need ot link register (MI) where you will receive the counts. The update will be at the beginning of each controller'scan.

I hope this answers your question.

Hi Emil, thanks, it has turned out. Only counter reset doesn't work.

[Emil]

What you selected in Hardware configuration? If you select HSC plus reset you need ot connect Reset signal ot I6.

[Kostya]

I selected both the counter and the counter with reset. It is installed 0, then on old value.

The first half first second

The second half first second

The first half second second

The second half second second

Outputs which on the controler, are normally dropped. The account begins with 0.

Dear Kostya,

SB3 is 1/2 sec ON and 1/2 sec off. I don't understand what exactly you want to perfom, but if you want to reset the counter, you need ot use special procedure. Please take a look on examples (VisiLogic > Help menu > Examples...).

[Kostya]

Добрый день Эмиль. Я имел ввиду, что счетчик не сбрасывается на 0 никакими способами. И в режиме debug не возможно записать в него никакое значение.

Hi Kostya,

This is a known iassue. HSC on expansion moduloes cannot be reset in the way you are trying.

In U90Ladder > Help menu > Simple application > Motion control there is demo application HSC Reset.

It's here attached...

Thanks, Emil.
