5.1.2 P2P Setting Parameters
While high speed link is a periodical communication, the P2P communication is a services used to communicate with
correspondent station when specific events occur. P2P can be used to transmit error information of a certain station to
correspondent station, or for the communications requested by specific contact point input. While the data size used in the
high speed link is word (16 points) unit, P2P communication can carry out communication with correspondent station
according to the data types such as bit, byte, or word.
(1) P2P service
(a) This service makes the RAPIEnet I/F Nodule act as a client on the network.
(b) At occurrence of predefined events, read from or write in the memory of the correspondent station.
(c)
This service is used for the communication with other vendors‟ devices which do not support XGT or mode bus protocol,
or transmission/reception of the desired frame.
(d) Maximum 64 independent P2P blocks can be defined in each module.
The table below presents the specification for setting up P2P parameters.
