EGD OPC Server with Signature Implemented

There is a network of controllers (MarkVI, PAC's and 90-70 controllers) managed with an EGD configuration server, where signature of each exchange is evaluated by the controllers to verify if they are valid to consume.

I need an OPC to communicate with this network and the driver should be able to Consume and Produce exchanges, the thing is that neither Kepware's nor Matrikon's implementation of the protocol has the signature option.

I'm visualizing the EGD packets produced by these servers and the signature field value is always 0.

I haven't tested what happens when the controllers receive a signature 0 exchange, but I'm assuming that they will ignore any signature different than the one indicated by the configuration server.

Any ideas or suggestion of other OPC servers?
