Title: subnet mask for H2-EBC
Post by: BretB on April 19, 2007, 01:20:22 PM

Does anyone know how to set a subnet mask on an H2-EBC?

I have a method that broadcasts our network to find any EBCs on it, by eliciting a response from them.  It then "registers" those who responded and sends them messages asking them for the statuses of their switches.

I can't have my entire (several hundred workstation) network being polled all the time for this.  I need to contain it to a subnet, like by using a subnet mask.

I saw that the user interface of the EBC/PLC software was not made to do that.  Can someone tell me how/where to code that in?

Thanks.

Since the H2-EBC does not "master" anything (i.e. it only speaks when spoken to), then there is no need for a subnet mask. It is not originating any "new" packets for TCP/IP, so it doesn't utilize a subnet.

Thanks.  Due to a combination of factors, we decided not to poll for the addresses of the EBCs, but rather to list them in a settings file and have our program read from that file and go get the data from the EBCs that way.
