ASTM Ensemble Interfacing

Dear All

I am trying to interface LAB instruments with LAB System using ASTM over TCP. I read the documentation here . But I can't understand how to connect instrument and LAB system in same port, please see the screenshot of interface below. Please help.

Details:

  • For Servece I use "EnsLib.EDI.ASTM.Service.TCPService" class.
  • For Proccess I use "EnsLib.MsgRouter.VDocRoutingEngine" class.
  • For Operation I use "EnsLib.EDI.ASTM.Operation.TCPOperation" class.

Hello Omar,

What problem exactly are you having? It sounds like you have a reasonable configuration.

"The Ensemble architecture prohibits a business service from initiating transmissions outside Ensemble. Replies to received documents are fine, but there is no provision for a business service to initiate an exchange with an entity outside Ensemble.

To adapt this restriction to ASTM conventions, Ensemble provides a special-purpose business operation for use with ASTM business services. This business operation identifies the incoming ASTM business service as its partner service. Whenever any member of the Ensemble production needs to initiate communication to the external device, it invokes this business operation, which sends the transmission out via its partner service. This preserves the Ensemble conventions for internal messaging (a business service may send messages to a business process or business operation only) while leaving room for ASTM conventions (there is only one TCP socket available on the device, and at the other end of this TCP connection is an Ensemble business service)."

Basically, you configure the operation with a connection to your ASTM TCP service and then the operation will be able to "use" the same port.

Does this by any chance have something to do with connecting a VGAstyle pin connector to a TCP connector?

Thank you for reply guys

it's ok now, but I think I have to import ASTM schema structure. from where I can download it?  I got the following error:

Build Map Status = 'ERROR <EnsEDI>ErrMapDocType: No ASTM schema structure is defined for DocType 'E1394:''
