4.3 ProSoft Wireless Protocol Functional Overview
The ProSoft Wireless Protocol (PWP) driver can be used to interface many
different protocols with PWP devices. PWP allows one controller to produce or
send an area of its memory onto a network at a specified rate. It also allows
another controller to consume or receive this data. Each data message contains
a data sample, or snapshot, of a specific portion of the producing node's
memory. Data messages are uniquely identified so that consuming nodes can
relate the incoming data with a specific configuration (known as an exchange)
which describes key characteristics of the data sample. A node can contain a
number of these exchanges, so that it may be both a consumer of some
exchanges and a producer of others at the same time.
Periodic Data Services provide an efficient mechanism which allows the repeated
transmission of a set of variables from a controller which
produces data, to one
or more controllers which consume the data. Significant features of the Periodic
Data Service include:
ƒ
A single request for data from a consumer controller can cause data packets
to be sent repetitively from the producer.
ƒ
The set of data variables to be sent periodically can be pre-defined so that
the controller starts sending the data as soon as it is initialized.
ƒ
Data can be sent to the specific node that requested it, or simultaneously to a
group of nodes.
