Direct cable connection between PC and NY4114-based node(s)

Connection between PC and NY4114-based node using a switch

NYCe 4000 machine network is supported. Multiple NYCe 4000 machine
networks (using physical multiple network interfaces or by defining multiple
subnets on one network interface) are not supported.
If the NY4114 MCU is configured to operate as an EtherCAT Slave, ETH port
1 is an ethernet port, and ETH port 2 and ETH port 3 are configured as
EtherCAT ports.
If ETH port 2 and ETH port 3 seem to be unresponsive in a
NYCe 4000 network, most likely the EtherCAT flag is set. Use the
web interface of the MCU to reset the EtherCAT checkmark and
download the firmware to the MCU.

If the system consists of more than one node, the nodes can be daisy-chain
connected. The number of NYCe 4000 nodes you can connect in this
topology for an LMS is limited to 24 nodes.
fig. 14-4 "Direct cable connection between PC and NY4114 node(s)" on page
209 shows a daisy-chained network using NY4114 MCUs. The NY4114 MCU
has 3 ethernet ports, and therefore also supports a binairy tree topology.

Fig. 14-5: Connection between PC and NY4114-based nodes using a switch
(method 1)
In this configuration the PC is connected to a switch. All NYCe 4000 nodes
are connected to ports of the switch. Not shown in the figure is the possibility
to build a binary tree toplogy. Further, not shown in the figure is the possibility
to connect other ethernet devices to the switch. The number of NYCe 4000
