What is Network Interconnection?
Section 7-1
2.
A gateway is used between Communications Units to connect different
types of networks.
• Communications across bridges or gateways can include up to three net-
works, including the local network (data generating network).
Although 2,012 bytes of data (including the header) can be sent and received
with a Controller Link, the maximum amount of data is limited by any network
the data passes through, i.e., the network with the smallest capacity will deter-
mine the limit.
If, for example, data passes through a SYSMAC LINK network as shown in
the figure on the preceding page, the amount of data sent and received from
the Controller Link is limited to 552 bytes (including the header) because the
SYSMAC LINK Network can only handle that many bytes.
See the manual for the network you are using in order to determine the maxi-
mum amount of data for each network.
