Routing Tables (See page 86)
Routing tables are set using the Support Software to specify paths for sending
and receiving data between networks. The routing tables consist of the follow-
ing two tables.
• Local Network Table: Set the combination of unit numbers and network
addresses for each Communications Unit.
• Relay Network Table: Set the communications path between the sender
and receiver.
1-3-4 Message Service
The SYSMAC LINK Units support SEND(90) and RECV(98) instructions for
reading data from and writing data to other node PLCs. The SYSMAC LINK
Units also support CMND(490) instructions for sending and receiving FINS
commands that control PLCs and CPU Bus Units. Using these instructions, it
is possible to control complicated functions without creating a communica-
tions program.
Refer to SECTION 6 Message Service for details.
1-3-5 Remote Programming and Monitoring
Remote programming and monitoring can be performed between SYSMAC
LINK, Controller Link, and Ethernet Networks. A maximum of three levels of
network communications (including the local network) are supported.
Refer to SECTION 7 Remote Monitoring and Programming for details.
1-3-6 RAS Functions
The SYSMAC LINK Unit supports RAS functions to help protect the network
and recover from errors.
Internode Test Communications between the local node and a specified node within the net-
work can be tested. The test settings are made using the Support Software.
Broadcast Test All the nodes within a specified network can be tested using the Support Soft-
ware broadcast test function.
Error Log
(See page 137) If an error occurs in the Unit, the time of the error and the error contents are
logged in EEPROM within the Unit. The logged error information can be read
using the Support Software.
Polling Node Backup
(See page 143) If an error occurs in the polling node, the Unit at another node automatically
becomes the polling node and rebuilds the network.
Node Bypass
(See page 143) If a backup power supply is used with an Optical SYSMAC LINK System, any
node that goes down will be automatically bypassed, preventing the entire
network from going down.
1-4 Programming Devices and Support Software
The CX-Programmer is needed to use a SYSMAC LINK Network.
