Re: Reading Array of Int
Hi Julian, unfortunately I think I found a regression in your code. I am using the compiled 0.8.0-SNAPSHOT version of the library which fix the reading of INT Arrays, unfortunately this version isn’t no more able to real STRING Array !!! When I call a sync read of a STRING the |PlcReadResponse syncResponse = readRequest.execute().get(); | never come back, it freeze forever. Here are the captured frame when I ask for |--field-addresses '%DB1:6.0:STRING[6]'| via the HelloPlc4x Request: |S7 Communication Header: (Job) Parameter: (Read Var) Function: Read Var (0x04) Item count: 1 Item [1]: (DB 1.DBX 6.0 CHAR 8) Variable specification: 0x12 Length of following address specification: 10 Syntax Id: S7ANY (0x10) Transport size: CHAR (3) Length: 8 DB number: 1 Area: Data blocks (DB) (0x84) Address: 0x30 .000 0011 0... = Byte Address: 6 .000 = Bit Address: 0 | Answer: |S7 Communication Header: (Ack_Data) Parameter: (Read Var) Function: Read Var (0x04) Item count: 1 Data Item [1]: (Success) Return code: Success (0xff) Transport size: OCTET STRING (0x09) Length: 8 Data: fe0474657374 | The PLC respond correctly |0474657374| -> |test| STRING. I have downgraded the library to the 0.7.0 just for testing and it works, the answer on the wire is the same and the |get()| call report the data correctly. Is this a regression?

Re: Reading Array of Int
Hi,
sorry for the delayed working on it but I just took a look and think I fixed
the issue.
It seems that arrays where not properly implemented in the S7 Driver (?).
I opened up a PR (https://github.com/apache/plc4x/pull/175) and hope that
@Christofer Dutz finds some time to have a quick look (as he did most of the
work there) and merge it, if he agrees with it.
If you could try out the branch and give your feedback I would be happy.
Thanks for the excellent preparation of work! : )

Unfortunately my java knowledge are not so advanced to fix the bug in
reading the array in a single command, anyway there’s a workaround.
Hope this mail help some newbies like me to find the right way to read data
from the PLC.

Hi Stefano,
I have made several modifications to the branch for a 0.6.1 revision.
If you have the time to try it you can download it from here
https://github.com/glcj/plc4x/tree/s7alarm
and a number of examples here,
https://github.com/glcj/PLC4XS7Examples
What version of PLC do you have?
Like the rest of the team, I will order to help you if you find any problem.

Reading Array of Int
Dear plc4x forum, I have found a possible problem in reading an array of INT. I am using the HelloPlc4x app for testing and I am trying to read the field address: |'%DB1:274.0:INT[3]'| In the request, captured via wireShark I can see the query: |Frame 3: 75 bytes on wire (600 bits), 75 bytes captured (600 bits) on interface utun2, id 0 Null/Loopback Internet Protocol Version 4, Src: 192.168.100.4, Dst: 192.168.1.192 Transmission Control Protocol, Src Port: 54543, Dst Port: 102, Seq: 1, Ack: 1, Len: 31 TPKT, Version: 3, Length: 31 ISO 8073/X.224 COTP Connection-Oriented Transport Protocol S7 Communication Header: (Job) Parameter: (Read Var) Function: Read Var (0x04) Item count: 1 Item [1]: (DB 1.DBX 274.0 INT 3) Variable specification: 0x12 Length of following address specification: 10 Syntax Id: S7ANY (0x10) Transport size: INT (5) Length: 3 DB number: 1 Area: Data blocks (DB) (0x84) Address: 0x000890 | and the response: |Frame 4: 75 bytes on wire (600 bits), 75 bytes captured (600 bits) on interface utun2, id 0 Null/Loopback Internet Protocol Version 4, Src: 192.168.1.192, Dst: 192.168.100.4 Transmission Control Protocol, Src Port: 102, Dst Port: 54543, Seq: 1, Ack: 32, Len: 31 TPKT, Version: 3, Length: 31 ISO 8073/X.224 COTP Connection-Oriented Transport Protocol S7 Communication Header: (Ack_Data) Parameter: (Read Var) Function: Read Var (0x04) Item count: 1 Data Item [1]: (Success) Return code: Success (0xff) Transport size: INTEGER (0x05) Length: 6 Data: 000a000b000c | The 3 INT I would like to read are there: |000a|, |000b|, |000c| but in the response of: |PlcReadResponse syncResponse = readRequest.execute().get(); | only the first one is present. I read in jira that there was a similar bug here PLC4X-57 <https://issues.apache.org/jira/browse/PLC4X-57>, is this the same problem? Thanks for your help.
