Select the checkbox for PTP enable for each port that requires PTP – this includes the PLC and all Kinetix5700 drives. When complete press the write button at the bottom of the page. Set Operation IEEE 1588/PTP to On and set PTP mode to v2-boundary-clock. Step 2: Browse the main menu to Time -> PTP -> Global. Step 1: Connect to the switch on Port 3 and open the web interface using HiView. If there is a duplex mismatch, for example the switch port is set to auto negotiate and the Kinetix drive is set to 100/Full, the switch will default to half duplex which will prevent PTP synchronization. This can achieved by ensuring that all devices and switch ports are set to auto negotiate or by individually setting all devices and switch ports to full duplex manually. As a prerequisite this guide will assume the switch has been configured with an IP address and the user has HiView.Īlso note that PTP requires all devices to be communicating in full duplex. This guide will provide the steps to configure 2 ports to be PTP enabled. Switches using the Classic OS platform are mostly limited to PTP simple mode which allows the switch to set its internal time using PTP traffic from a master close (such as a PLC), however the switch is unable to forward PTP traffic making it impossible to establish a synchronization between the PLC and Kinetix5700.
This guide is for Hirschmann switches using the HiOS platform such as the OS20/30, RPS, RPSE, etc. PTP (also called CIP sync) communication is used to do achieve this time synchronization.
Kinetix5700 drives must be time synchronized with the PLC to ensure commanded position and velocity matches actual position and velocity at a given time. PTP (Precision Time Protocol) is a procedure described in the IEEE 1588-2008 standard that enables the clocks in the network to be synchronized to a degree of precision of just a few 100 ns.
