Applications Precautions
Section 1-4
• To construct a network that uses a node address higher than 32, it is nec-
essary for all nodes to be one of the following Units: 3G8F7-CLK21-EV1,
CS1W-CLK23, CJ1W-CLK23, CS1W-CLK21-V1, CJ1W-CLK21-V1, or
3G8F7-CLK23-E.
In addition, the Wired Network 62 Node Enable Bit in the DM Parameter
Area software switches of all nodes must turned ON to enable 62 nodes
maximum. With the 3G8F7-CLK23-E and 3G8F7-CLK21-EV1, make sure
that
Max Node Number set 62
is selected in the FinsGateway driver prop-
erties. If different settings are specified, the network will not be correctly
configured.
• The
Max Node Number set
62 DM Parameter Area software switch for
the CS1W-CLK23-E, CS1W-CLK 21-EV1, CJ1W-CLK23-E, and CJ1W-
CLK 21-EV1 Units is enabled when the power is turned ON again.
• When using automatic data link creation with 1:N allocation, all nodes
must be following Units/Boards. Other models cannot participate in data
links that employ 1:N allocations.
Note
Lot numbers 030601 or later.
• If the total number of data link words is increased, the PLC cycle time and
the communications cycle time will be increased. In that case, observe
the following precautions.
• Check to make sure that it will not cause problems if performance in
responses to external devices is reduced.
• In message communications, extending the communications cycle
time may result in timeout errors waiting for responses.
In that case, lengthen the response monitor time as described below.
SEND, RECV, and CMND instructions:
