Fipway network
The operating principle of a Fipway network gives ensured, constant network cycle
times whatever the traffic and number of stations (2 to 64). This enables the Fipway
network to be updated (addition or removal of stations) without changing
the performance.
Maximum transmission time
b Telegram (TLG): priority application messages are transmitted in less than 10 ms
(one telegram per station).
b Common words (COM): the database of common words is updated every 40 ms.
b Shared Table: the exchange table is updated every 40 ms.
Uni-TE message handling system: Uni-TE or standard application-to-application
messages are normally transmitted in less than 80 ms (40 ms for stations with
addresses below 32). Where there is a large amount of traffic, some messages can
wait for several cycles before being transmitted. The network characteristics enable
a maximum of 210 messages of 128 bytes per second to be transmitted.
The performance can be improved by inhibiting the Telegram service in the network.
With such network characteristics, the response time at application level depends
almost exclusively on the processing capacity of the devices which are connected.
For example, the remote loading of a 50 K word program takes less than two minutes
on a network with normal load.
CT1 = Cycle time of device 1.
NCT = Cycle time of Fipway network.
CT2 = Cycle time of device 2.
The response time must be evaluated by the designer of each application in relation
to the devices connected.
The processing time of a device can vary from one to two cycle times as a function
of asynchronous operation.
