[?]: Connecting to two PLC using DASSIDIRECT

[reymond_craig]

Hi,
i have a problem connecting Intouch to two S7300cp 343-1,
i can connect to one of the plc but cannot at both.
I already configure them both have at archestra, and also with access name.
Is this possible to connect on two cp,
or i need to throw my data to the other cp and then communicate on that cp only.

Thanks and warm regards,
Rey

Hi reymond_craig

You can connect how many cp (cpu) you want.
At the momment, for example in my office DASSIDIRECT work with 11 CP.
Everythink depends from access name, which will be using (calling) from intouch.

Hi Umencho,

Thank you for your help, the problem was solved, I just explore the archestra and i found out that i can put another cp on the same node(just right click on New_PortCpS7_000 and insert cp), i thought i need another node for another cp. It's success right now.

I have one more question, I want to query or export my historical data (.lgh and .idx) to excel do you have tools to do tihs or way to do this. Thank you very much in advance.

Thanks and warm regards,

I have one more question, I want to query or export my historical data (.lgh and .idx) to excel do you have tools to do tihs or way to do this.

I also have some question regarding to my historical trend, I want to always display the entire data of the chart in real time( let say the range of my trend is 5 minutes then after runtime of 5 minutes its already populated of data, when i transfer to other window let say to my alarm window and then I go back to my trend window it goes back to initial trend and don't display a populated trend.)

Hope there is solution here other than displaying history.

Thanks and warm regards,

Hi

about historical trend display the entire data in real time try this script for trend window: Condition: While Showing
IF HistTrend_RealTime THEN HTUpdateToCurrentTime("HistTrend"); ENDIF;
about "export my historical data (.lgh and .idx) to excel" I never used this option. But you can start HistData and read about this topic. for also is interesting this and I'll try in my office later and post the result.

regards

P.S. HistTrend_RealTime is Memory Disctrete Tag

hi umencho,

Thank you for your help, I tried the script but it don't work on mine.
I'm using intouch 9.5.
I hope you know other solution.

Hi

It's my mistake that script didn't work. In trend window you must add one check box (from wizard selection - windows controls) and put tag "HistTrend_RealTime". And then if you mark this checkbox your historical trend will be work like real time trend, but with selectible tags.
But must put script in window.

Hi Umencho,

I don't know why It don't work on me, did i need to put the same script as you gave me before(IF HistTrend_RealTime THEN HTUpdateToCurrentTime("HistTrend"); ENDIF;) to window script?

Thanks and warm regards,

Hi reimond_craig

Yes, put this script in windows, and make this checkbox wih this tag HistTrend_RealTime. In script you saw, if mark this checkbox, means in this tag forced one, then current time in historical trend goes to count like system watch.

Hi Umencho,

I Thank you for your support but I still can't do for some reason, The checkbox is already working with the tag HistTrend_RealTime I already check this by using a light. I have two Hist Trend tag type but I can't delete one of them( I'm suspecting that one of them makes the conflict) even when I update used counts of tags. I hope I don't disturb you that much. Thank you very much Umencho.

Warm regards,

Hi

make update, after that delete unused tags and select which tag you want to delete. In your case HistTrend_RealTime. Or make another tag for example HistTrend_RT and replace with old one (in script and combobox).

Hi Umencho,

This is really strange, still don't work here. I don't know what I should do, but is this historical data going to update by this even there is no change in process variables? Thank you very much.

Warm regards,

Hi

The Hisorical data with this option will looks like real time trend. You will see every tag which conect to the trend, doesn't metter change or no it's value.

Try this project http://www.filecrunch.com/file/~s5y5n4
Made with Intouch 10. And connect with your access name.
