HI Gaurav,
I would probably use a byte-array field, but no idea if the DF1 driver supports
that:
Theoretically this would look like this:
PlcReadRequest request = plcConnection.readRequestBuilder()
.addItem("N7:1", "5:USINT[12]")
.build();
Hope that helps.
Chris

Betreff: Re: DF1 protocol ...cant find documentation
Hi Chris,
Currently, for testing, I am creating a web service API that will use PLC4X to
construct a command and expects a command as hex string which can be used by
native client to send command ?
Code
PlcReadRequest request = plcConnection.readRequestBuilder()
.addItem("N7:1", "5:INTEGER")
.build();
How do I get a command which is constructed and send as hex like 10 02 08
09 06 00 02 04 03 10 03 E0 from the request builder ?
Thanks and Regards ,
Gaurav
