Configuring a Network with 33 Nodes or More
Problem Status Cause and remedy
The node is not
present in the net-
work.
(ERC indicator: ON
RUN indicator: OFF
INS indicator: OFF) The ERC indicator is
ON in the CS1W-
CLK21-V1 or CJ1W-
CLK21-V1, and a
node address higher
than 32 is set. The Wired Network 62 Node Enable Bit
in the DM Parameters Area is turned
OFF. Turn ON the Wired Network 62
Node Enable Bit and then turn the
power supply OFF and ON again.
The ERC indicator is
ON in the C200HW-
CLK21, CQM1H-
CLK21, CVM1-
CLK21, CS1W-
CLK21, or CJ1W-
CLK21, and a node
address higher than
32 is set. The Units that can be used to configure
a network that uses a node address
higher than 32 are the CS1W-CLK21-
V1 and CJ1W-CLK21-V1 only. Either
configure the network using compatible
Units and Boards, or split the network
into two separate networks.
The node is not
present in the net-
work
(ERC indicator: OFF
RUN indicator: ON
INS indicator: OFF) The INS indicator is
ON for some nodes
in the same net-
work. Those nodes
are C200HW-
CLK21, CQM1H-
CLK21, CVM1-
CLK21, CS1W-
CLK21, or CJ1W-
CLK21.
The INS indicator is
ON for some nodes
in the same net-
work. Those nodes
are CS1W-CLK21-
V1 or CJ1W-CLK-
V1. The Wired Network 62 Node Enable Bit
in the DM Parameters Area of the poll-
ing node (CS1W-CLK21-V1 or CJ1W-
CLK-V1 with INS indicator ON) is OFF.
Turn ON the Wired Network 62 Node
Enable Bit, then turn the power supply
OFF and ON again.
The maximum number of nodes set in
the network parameters is less than the
number of nodes present in the net-
work.
Use CX-Net or the Controller Link Sup-
port Software to read the network
parameters, and check the maximum
number of nodes setting. Set the maxi-
mum number of nodes to a number that
is the same or larger than the number
of nodes in the network.
The maximum num-
ber of nodes in the
network is set to 32. The polling node is a
C200HW-CLK21,
CQM1H-CLK21,
CVM1-CLK21,
CS1W-CLK21, or
CJ1W-CLK21. The Units that can be used to configure
a network that uses a node address
higher than 32 are the CS1W-CLK21-
V1 and CJ1W-CLK21-V1 only. Either
configure the network using compatible
Units and Boards, or split the network
into two separate networks.
The polling node is a
CS1W-CLK21-V1 or
CJ1W-CLK-V1. The Wired Network 62 Node Enable Bit
in the DM Parameters Area of the poll-
ing node (CS1W-CLK21-V1 or CJ1W-
CLK-V1 with INS indicator ON) is OFF.
Turn ON the Wired Network 62 Node
Enable Bit, then turn the power supply
OFF and ON again.
