nodes you can connect in this topology is limited to 62. NYCe 4000 nodes
can co-exist with other ethernet devices on the machine network.
The switch must support IEEE 1588 (PTP - Precision Time
Protocol). If the switch supports PTP Master it must be possible to
disable PTP Master, because the first MCU must be PTP Master
in the NYCe 4000 ethernet network.
An other network configuration is possible using the switch functionality
supported by the NY4114. In this configuration the (external) switch is
connected between the PC and only one NY4114. All other nodes are
connected to each other, not to a port on the external switch. The external
switch does not need to support IEEE 1588 PTP in this configuration.

Other devices with ethernet connection can be connected to the
NYCe 4000 ethernet network, but the following restrictions apply.
●
These ethernet connected devices must be installed outside
the IEEE 1588-aware NYCe 4000 segment, that is after the
last node.
●
These ethernet connected devices must not overload the
NYCe 4000 network with extensive data communication.
