Hi Gavin,
What version of PCo are you configuring?
Set up the Socket Agent with the socket type, name, IP Address and either the terminators or data length. (Note: control character terminators are specified in hex; i.e., CR-LF terminator is \0D\0A). then you can assign the name.Message variable to the trigger and/or an Output parameter in the Agent Instance Notification.
What is the destination of the Scale data? MII destination (transaction) or an RFC destination?
Regards, Steve
