Hi all,

I am trying to use an IE-AS-i-LINK gateway in TIA Portal.

In Step 7 you could assign an A/B slave with a nibble of I/O. You can also do this using a DP/AS-i LINK Advanced gateway in TIA Portal as this represents the AS-i slaves on the 'Network view'. The IE-AS-i-LINK does not.

The A/B slaves are addressed in the DP/AS-i LINK Advanced by setting the IO code of the slave to '3'. This will allow you to set the I/O Addresses as nibbles instead of bytes.

When the same principle is applied inside the IE-AS-i-LINK in 'Device view' the I/O addressing as nibbles is not allowed.

Does anyone know of a way to do this? Or am I stuck using whole bytes for every A/B slave when using an IE-AS-i-LINK?

Cheers,

Steve

Hi,

Can you upload some screenshot  about the problem? Also some more details about the configuration. Part numbers and things like this.

See attachement, if you need further info please let me know....

Cheers,

Hi,

I See...

 If you read Manual SIMATIC NET IE/AS-INTERFACE LINK PN IO under chapater "7.2.1 Addressing AS-i Slaves" you can read:

"Access when the GSDML file or STEP 7 is used for configuration (unpacked) If you configure with the GSDML file or use STEP 7 to configure, access to the digital data without “packing” is byte-oriented. One byte is assigned to every AS-i digital slave..."

So you basically waste 4 bits in each bytes.

What you can do is Pack the addresses, that is actually assign the higher 4 bits for each byte for the next slave.

Packing addresses is the same story as with the ET200s modules. See this link to see how to do it:

How can you group together the address area of the ET 200S in STEP 7 (TIA Portal) using the "Pack Addresses" function?

I hope I could help.

Hi MicroMan,

Thanks for the information, however the Manual only mentions Step 7, I am using TIA Portal. I did take note of the following section just under where you refered me to:

"Access when you configure with STEP 7 (packed digital data)

If you selected the “Pack” function in the properties dialog of the AS-i line proxy in STEP 7, the digital I/O data of all AS-i slaves will be transferred tightly packed in the data field of the line proxy. The bit address of the AS-i bits is calculated and displayed by STEP 7.

If a configured AS-i slave fails during runtime, this is signaled to the user program as a remove module alarm via the diagnostic address assigned to the slave. When accessing the digital bits of the AS-i slave, there is, however, no I/O error."

As the above passage suggests, I have looked at the 'Configuration AS-i proxy' for the AS-i lines under 'Module parameters'. The only settings that come up are 'Diagnostic interrupt' and 'Address programming'. I have tried playing with the 'Address programming' setting and it seems to make no difference.

I have looked into the packing of addresses in a similar manner to the ET200S modules. See attachment.

Unfortunately this doesn't work with the IE/AS-i LINK.

Cheers,

Steve

Hi,

Have you tried to highligth the modules in "device overview" and the rigth click?

Yes, already tried that.

Hi Steve, 

I gave it a shoot, but I did not find the packing option neither. What is available in Step7 classic, it should be available in TIA. Really strange, I think we are missing something basic here. I am sure there is a logical reason we can not pack these addresses. The thing is the manuals says we could be able to so that is interesting. maybe we try it with the wrong tool?

I think the Best way forward is raising a Support Request.  Please come back to us and let us known what is to be done!

whe you buy an IE/Asi gateway the best information is its manual .

this picture from my asi gateway you can go to the link and download the best manuals.
