function
Increasing the number of cyclic
points
master
Transfers ON/OFF information with remote I/O stations.
master
Transfers ON/OFF information and the numeric data with remote device stations.
master
device Transfers ON/OFF information and the numeric data with intelligent device stations.
compound Transfers data with remote I/O stations, remote device stations and intelligent device
stations.
Cuts off only slave stations in which data link is disabled by power OFF, etc., and
continues the data link using only normal slave stations.
Allows a slave station which was disconnected from the data link by power OFF, etc.
to automatically join the data link again when it recovers to normal status.
Sets the data link status (continue or stop) for a case in which an operation stop error
occurs in the master station PLC.
Sets the status (clear or keep) of the input (receive) data from a station in which data
link is disabled due to power OFF, etc.
case of Sets whether output (send) data to the slave stations will be refreshed or compulsorily
CPU cleared when the programmable controller CPU enters STOP mode.
Consistency control functions assure data consistency for 1 word (16 bits) or more
when read or written by the FROM/TO instructions, or data consistency for 2 words
(32 bits) or more when read or written by the DFROM/DTO instructions.
Sets slave stations to be connected in the future as reserved ones so that such
stations are not handled as data link faulty stations.
Sets slave stations as "error invalid" so that such stations are not handled as data link
faulty stations.
invalid station Prevents units specified from being treated as data link faulty stations temporarily
during online operation.
Stops or restarts the data link that is being executed.
check
Checks for the overlapping of number of occupied stations.
Allows the number of cyclic points per module to be increased from 128 points for RX/
RY and 16 points for RWr/RWw in the ver. 1 mode to up to 224 points for RX/RY and
32 points for RWr/RWw in the ver. 2 mode.
