Sean, If the external reference C.B.P is within the same CP as the sequence block a broadcast is not made to other CPs on the mesh network and the sequence code is not suspended. If the external reference C.B.P is in another CP then a broadcast is made and the sequence block will suspend one block period to process the external reference call. -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Redmond, Sean S Sent: Thursday, May 02, 2013 4:04 PM To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] HLBL help Thanks for your replies. Looks like you external references are more flexible than local references and I can not loop around locals. Another question. Does HLBL broadcast for an external reference if the link is in the same CP?
