6: Sample Layout Of Metasys Ethernet Router - Contemporary Controls Metasys JC-MER-CXB User Manual

Note: If the Ethernet network consists of multiple Ethernet segments,
the segments must be connected using LAN Routers that
support the TCP/IP protocol suite. Intermediate networks
that use other communications technology (FDDI, Token
Ring) are acceptable if the intermediate networks are high
speed. Low speed networks (e.g., 9600-baud serial lines) will
cause unacceptable delays to Metasys N1 communications.
The resulting network layout will be similar to the sample
network shown in Figure 6. Each ARCNET segment will have
one JC-MER-CXB attached to it. The ARCNET node address
on each JC-MER-CXB has been preassigned 255.
3. Assign a subnet address to each ARCNET segment. We
recommend using the subnet address "1" for the primary
ARCNET segment, or the segment that has the most devices
attached to it. Assign a unique node address to each NCM or
Operator Workstation attached to the N1 network. Node
addresses must be unique even if the NCMs are attached to
different subnets. Record the subnet and node address
information on the JC-MER-CXB Planning Form A.
