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.
#What is a hirschmann switch full
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. These switches are suited for small businesses that have limited budgets but need better security protection and want to improve their networks' performance.Configuring PTP in Hirschmann Switches for use with Kinetix 5700 Drives While managed switches cost more than unmanaged switches, the range of models available mean that there are different levels of complexity and cost for businesses of all sizes.Ī third type of switches, called smart managed switches, offers a compromise between cost and features. Typically, such networks power enterprise-level businesses, government agencies, universities, and healthcare organizations. Managed switches, with the flexibility and control they provide, are a must for networks where reliability and security are critical. Unmanaged switches are most often seen in very small, uncomplicated networks with only a dozen or so devices connected and without critical requirements for security and availability. How should I choose between managed and unmanaged switches? They also require more expertise to provision and manage, meaning added costs for staff with the skills to maintain the network Managed switches, with all their additional capabilities, cost more than unmanaged switches. Unmanaged switches are cheap, as well as very simple to run. Cost: For some users, cost is a significant choice driver.Unmanaged switches do not offer security capabilities. Managed switches provide security settings that can be configured to protect the network and to help identify threats. Security: Network security includes protection from and detection of threats to data and operability.These capabilities allow for optimization of network performance and availability. Managed switches can offer a huge number of features that can be configured by IT professionals, thus permitting a diverse array of deployment possibilities. They have no features besides what they need to negotiate transfer speeds and to determine each link's duplexing type. Capabilities: Unmanaged switches immediately start forwarding traffic once users have plugged them in.Managed switches and unmanaged switches differ in three areas: capabilities, security, and cost. What are the differences between managed and unmanaged switches?
