[?]: Wonderware Addressing of Siemens Memory

[reymond_craig]

Hi,

Good morning, I just want to ask those who know how I can put the address of siemens to item name of wonderware for example, m0.0 I put mx0.0 but I don't know on other data type like for word, Dword. Please help me out here.

Siemens Address Item Name (Wonderware)
Db1000.dbd20 ?
Db1000.dbw30 ?
Mw10 ?
MD20 ?

Thanks in advance

Warm regards,
Rey

You'd better read the IO manual:

**: For DDE/SuiteLink, this value is restricted to the range
of 0 to 2147483647. Values higher than that are clamped to
the maximum value of 2147483647 in a SuiteLink or DDE
client. In this case, the quality of the item shows "Clamp
High."
Note All data blocks are Read/Write. The longest string or
array that can be read in a cyclic service has the length of the
PDU size minus 32 bytes. The longest string the InTouch software
can process is 131 bytes. The longest string that can be poked is
256 bytes or the PDU size minus 28 bytes, whichever is less. The
SIDirect DAServer processes a write (POKE) to a Data Block.

Hi Frankw,

Thank you for your reply, i already ok with my address on word, but my problem now is on my double word. Every time i change the value of a doubleword in my plc it gives me a value 32767, i don't know why this happen. I used address for item name MD344

Another question regarding on historical trending, I log some tags and trend it on intouch. My question is what is the update time of my trend, I mean when it is going to show me the value of the tags on the trend. CAn i change this update time?

Thank you very much in advance.

Warm regards,
Rey

My question is what is the update time of my trend, I mean when it is going to show me the value of the tags on the trend. CAn i change this update time?

This update time's completely defined by tag update. It's means that new value shows up when any of displayed logged tags is about to update. If you mean the logging period it's definded by changing of the tag value too (by default). you can override this behaviour by forcing log period (see ForceLogging parameter of INTOUCH.INI in manual)

For DB's doublewords item syntax is something like iDBxxxx,DINTyyyy. "i" is a helper for IO Server used during type casting. Feel free to use Simatic NET docs. All syntax should be described there.

hi,

Thank you very much for the info, but this one is strange when i tried to go to runtime ( I used MD344 as item name) It always give me value that is equal to Max EU. 2nd is it the same the update on trend value of real time and historical. I like it to be historical but acts like a real time(with logs).

Thank you very much in advance,

Warm regards,

First of all what OPC Server do you use? If it's SIMATIC NET OPC try to use iMD344 or iMDINT344. What OPC Client provided by WW do you use? And of course check PLC offset

[bunglehead]

2nd is it the same the update on trend value of real time and historical. I like it to be historical but acts like a real time(with logs).

realtime trend update speed depends on global application settings (see windowviewer settings). Histtrend doesn't update automatically. You should update it by hands using HTUpdatetoCurrenttime (as I remember)

hi bunglehead,

Thank you again for your response,... I try to do what you say to me but it don't show me any value in wonderware if i put i before md344. I'm communicating intouch through DASSidirect, i think 'm not using opc server here. Thank you very much, we can still solve this problem.

Warm regards,
Rey

[bunglehead]

I'm communicating intouch through DASSidirect, i think 'm not using opc server here.

I see..You're right SIDirect doesn't use any OPC Server. Use off. doc in <cdrom>:\SI\DASSIDirect1.5\UserDocs\English\DasSIDirect.pdf of WW Device Integration CD2. Page 43 - Chapter 3 "Item naming".

[frankw]

like this:S7C_S7_001.MD334 use default Topic, or S7C_S7_001.TopicName.MD334

Hi,

Good morning, hope this morning will be good to me also. I try them but still i got this, the one that the wonderware display is the tag value in decimal, i want to display the value in real form. My tag is already set as io real on type but still the tag display in decimal form not in real values. Thank you very much in advance.

Warm regards
Rey

Did you read any manual materials for InTouch? All functions are very good documeneted. What string pattern do you use to display floating point number? Try to use 0.0

Yes,everything will be ok, writing the tagname by "Item naming" conversion.

hi,

Can i just leave -32767 to minimum EU and 32767 to max EU sa well as in Min and max Raw? I am using S7 317-2DP.
I think communication with my MD344 is ok but the trick is it display the decimal value of my real value in PLC. Can anybody knows how to display the real value in wonderware?

Thanks and warm regards,
Rey

[bunglehead]

Do you mean DINT? It's a 32-bit signed number..

Thanks and warm regards,

As wrote above use 0.0 text pattern when displaying value in window. Does your MDxxx contain REAL number?

[reymond_craig]

hi bunglehead,

Thank you very much to all of you, i missed something since you mention double integer, i find a way to convert my real value the result from scale fc5, i just round it and the result is dint. it is working now, thank you very much to all.

I hope i can find your help again the next time. Thank you very much.

One more is there anybody here who knows how to export in excell format the data from my history data?

Thanks and warm regards,
Rey

[frankw]

"Item naming" !
REAL FORMAT: S7C_S7_001.MREAL334 or 7C_S7_001.TopicName.MREAL334

[chandu1403]

Item name for real is MREALxxxx. If double word tag nmae starts with VDxxxx, use VREALxxxx in item name.
