I am very new to EDI. I am trying to write a Spring boot java program to convert EDI 214 (Shipment Status) and EDI 215 (Motor Carrier Pickup Manifest) messages to XML using Smooks. Looking at EDI 214 data elements, I couldn't figure out a easy way to write EDI-to-XML mapping XML with all the data elements. Is there any easy way to get correct Smooks mapping XML.
Thanks,

I am unable to understand the CANopen Protocol. I am aware of the working of CAN and how a CAN frame looks like. A CAN data or remote frame contains the Start of Frame , Message Identifier Field, DLC, RTR , Data(Payload), CRC , ACk fields, etc. I am aware that the CANopen standard utilizes the CAN bus to send the CAN messages. However , the way in which a CANopen's CAN frame looks is different where it contains a COB ID+Node ID in the Message identifier field and in the payload field , it contains object dictionary related information. I would like to ask the following questions therefore:
How are the object dictionaries defined. I am aware that it is a
table containing an ID , sub ID, Datatype information about the data
it contains , the manufacturer information for the respective data
entry , etc . Are they all hard coded as an m*n multidimensional
array in the software stack?
I am confused with the terms transmit PDO and Receive PDO. Is it similar to CAN data frame and CAN remote frame ?
What is PDO mapping and how can i identify which object ID in the object dictionary is mapped to which object ID in the PDO mapping
table. Both use the same terms Object ID ?
I am actually very new to CANopen and i have asked these questions based on my initial understanding. I was unable to find a detailed explanation in the CiA website.
Thank you in advance

It is not so easy to understand it!!
CanOpen is a communication between Master (client) and Slave (server).
An device like a sensor is a Slave.
The slave has an OD (object directory). The manufacturer provides all informations about it. Ex. if i want to read the temperature, its location is at adress 0x2040 at sub index 00. Then the master (our system) needs to make this request. To do this, you need to configure the device by sending some request (with SDO) in order to change the TPDO1 mapping (0x1A00) and TPDO1 communication parameters (0x1800). And be able to receive by the device the temperature. The device will not work alone.
SDO (read/write) allows OD access entries. Ex. change the TPDO1 mappings.
PDO is the output/input to the device once operational.
There is NMT Master commands to put the device in operational mode or to send a SYNC or Heartbeat. Depends what the device needs?
Ex. 080h 00 : SYNC send by master
280h 06 E5 EF 02 00 00 00 : response of device by TPDO2
000h 02 01 1F : put the device with ID = 1F in operational mode
If you want a good example device POSITAL FRABA absolute rotary encoder with can open interface.
Hope this will help you a little bit!!!
I'm writing a parser for the SQLi-protocol ("turbo") used by Informix. I have most opcodes covered by now, yet SQ_FETCHBLOB I don't have a clue yet. Reverse engineering the driver is difficult since it copies values from its internal state machine, which itself is hard to track. All I know is that SQ_FETCHBLOB is followed by 56 bytes of data, some of which seem to be the BLOB's total size and fetch-offset.
Does anyone have some information on how to decode SQ_FETCHBLOB as used by Informix SQLi ?
I can't comment on the specifics of the SQ_FETCHBLOB SQLI packet type but you might want to look at the file $INFORMIXDIR/incl/esql/blob.h which is shipped with Client SDK. This describes the tblob_t data structure which is 56 bytes.
I'm working with a ELM327 and I'd like to be able to set the header and data portions of CAN messages to be sent. I see that there is a code for setting the header for messages
SH xxyyzz
But I'm having trouble finding out how to set the data portion and control when the message gets sent.
Do these both occur when I send a ASCII request for a PID with extra characters for the data field?
And would that use the header that was set by the SH command?
Is there a better way to do this?
Datasheet: http://elmelectronics.com/DSheets/ELM327DS.pdf
If you're using the ELM327, and you're on a protocol such as J1850 vpw, or J1850 pwm (older than 2003 CAN vehicles).. Then you will use this to set the header.
The header will consist of xx yy zz
xx = priority of message (i.e. 68)
yy = Target address of module you want to talk to (i.e. 5A)
zz = Sender address, which can usually be F1
So your command would look like this ATSH 68 5A F1
This sets the header.. Now you want to send data. Any data you send from now on will use that header, and send the data to that module.
So if you wanted to get the RPM's, you can just send 01 0C
You will get something like 41 0C 23. The last data byte is the value of RPM's. You will have to figure out the formula to convert this into a human readable format though.. A lot of information can be found here..
https://en.wikipedia.org/wiki/OBD-II_PIDs
By the way, if you're communicating on a CAN network, you would just use the module ID as the header.. ATSH 7E0, then send your data. all vehicles 2008+ are CAN.. some 2003-2007 are also.
This might be an old question, but I just found an online link which describes in detail how to send arbitrary CAN messages using the ELM327. So anyone (like me) coming past that question can still find a valid answer.
Look here for details on send arbitrary CAN messages with the ELM327:

If you're using an ELM327 chipset, you need to call ATSH or AT SH, to set the header first. Then send the message separately (The data bytes).

I can make USB HID work in Delphi (2010) for simple stuff (one endpoint, ReportID = 0).
But now I need to send 96 words (192 bytes) of data every millisecond. I see how to do that in the slave (PICmicro) with three 64 byte endpoints. (Full speed Interrupt transfer is limited to 64 bytes per endpoint.) But I don't see either a more flexible USB/Delphi object or a way to specify endpoints in the JvclHIDDeviceController object.
Is ReportID telling me the received endpoint?
Is ReportID telling me the received endpoint?
No. When used, it is the first of the 64 (maximum) data bytes.
I need to send 96 words (192 bytes) of data every millisecond
Using WinUSB (or LibUSB-win32) and a bulk pipe sounds simpler to me than trying to create and access a composite device with 3 HID interfaces.
This process is same like 850 file or if differs,Please describe as flowchart to process of 860 file.
My question is :-
How to process to parse 860 file?
what are the changes requested in 860 file?
The 860 is a Purchase Order Change. It is basically just that: an amendment or change to a Purchase Order. You didn't specify inbound or outbound, so I will try to keep it generic.
When the 850 is sent, the purchaser might go back and realize the PO needs to be changed. Perhaps a line item needs a quantity adjustment (20 EA instead of 10 EA). Perhaps a line item was omitted. The 860 could be used as a Cancellation, Add, Delete, Change, Replace, or Duplicate. The partner's implementation guide should give you a clue as to how it is used.
You would parse it just like any other EDI document, except you need to look at the different segments and elements. The BCH01 will tell you what kind of Change it is. In some cases, I've seen it where it replaces the PO exclusively, and you are able to drop the original PO and put this in the place (the structure is very similar to the 850, with some segment changes). In other cases, I would just print the 860 off to a human readable format (HTML), and give it to the business unit, because I didn't want to change open orders.
In some scenarios, the life cycle might look like this:
send 850
receive 997
receive 855 (PO Ack)
send 997
send 860 (need to change the PO)
receive 997
receive 865 (PO Change Acknowledgement)
send 997
And then:
receive 856 (Advance Ship Notice)
send 997
receive 810 (Invoice)
send 997
