Controller Link Unit
The SEND or RECV instruction sends or receives data in an area of a particu-
lar node.
The SEND instruction sends data from an area of the local node and writes to
an area in the designated node.
The RECV instruction requests the designated node to send area data and
writes the data to the local node.
The CMND instruction issues a command to read or write data of other
nodes, control, or read error logs. With the Controller LInk Unit, OMRON’s
command protocol called “FINS commands” is used.
trary commands cannot be issued.
RAS performs real-time monitoring of the network status. If an error occurs in
the network, RAS records and displays the time and contents of the error.
Data Link Status Area
When the data link function is used, the data link status is reflected in the data
link status area of the PLC.
Network Status Area Other than the Data Link:
The network status such as the state of node participation is reflected in the
status area of the PLC.
The error log function records contents (codes) and times of errors that occur
in the network into the RAM or EEPROM, up to the maximum of 64 (see note)
errors.
The recorded errors can be read using the Controller Link Support Software
or the message service function.
