event triger

[Zeus]

Hi,
I got a problem. I am trying to config input channels. The type of channel is calculated real. I checked event and event onchange. But there is no event triggered on the webstation.

the count of input channels is 19900. whether or not it is the reason that caused the problem.

Hi,

May be events are created but not displayed. Did you click “All Events” button of the events table?
Also you should open the archive files in Administrator and check if events presented or not.

If you change language to English, open channel properties form, and make a screenshot of all channel properties, it would help.

hi
I got a new problem.
I created a new channel. its type is calculated real. I use formula below

“GetBit(Val(1001),0);Cnl==0?115:116”

I checked the option ‘onchange’.
There are always two events.
The first one is caused by value change and the second is caused by status change.
How can I fix it. thanks alot.

The same garbage for two events, the formulas seem to affect the creation of duplicates.

Hi,

The formula is incorrect. Could you provide a screenshot of all properties of this channel?

hi
i am waiting online.

Hi,
1. Set Signal to blank
2. Update the formula to GetBit(Val(1001), 0); GetBit(Val(1001), 0) > 0 ? 116 : 115

Hi,

Likely, you should not set the channel 2570 from itself.
The formula of the channel 2570 should be: Val(2510) > 0 ? Val(2526) : Val()
