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.
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.

Introduction
If the motion control system consists of one node, you can use a direct cable
connection between the PC and the node. If the motion control system
consists of more nodes, the following methods of connection are available.
1. The nodes are connected using a "binary tree" topology. The "binary
tree" topology minimizes the "depth" of the network and thus reduces
latency times. This is for an NY4114-based network the preferred
topology.
2. The nodes are daisy-chain connected. The PC connects to the first
node, that node connects to the following node, etc.
3. The nodes are connected to a switch. The PC connects to the switch, all
nodes connect to ports on the switch.
4. A combination of the previous two methods. You can use a switch to
connect the PC to a node, and connect an other node (or nodes) to that
node.
The NY4114 MCU is only supported in NYCe 4000 Software
Release 50V02 or higher.
The network adapter in the PC that connects to the NYCe 4000 machine
network must be configured to be in the same subnet as the MCUs. Only one
