To Join the Telephone Conference . . .
Dial Please specify conference ID Upgrade Boundaries RS5K V2 to present– CFlash local chassis modules only V13 and prior f/w releases – Hyperterminal was required to SERCOS drives, UltraWARE for U3K V13 – Implemented “Browsing” over SERCOS to the servo drive using RSLinx Important because you can now see the drive through RSLinx, although you cannot flash to it. V13 - AutoFlash was implemented for motion modules in the chassis (not drives). V15 - ControlFlash & AutoFlash over SERCOS implemented (1756-RN619C-EN-E & 2094-RN006E). V16 - Firmware Supervisor Implemented V17 – Kinetix 6200 introduced – CFlash capable V18 –Kinetix 6500 introduced – CFlash capable V19 – Kinetix 300 – Uses MotionView for upgrades V20 – Kinetix 350 introduced – CFlash capable (hardware available now) We will send a link to a recording of this broadcast following the WebEx session.

How Does CIP Motion Work? --- Simple Analogy
CIP Motion coordinates devices in a manner that’s similar to our own methods for coordinating meetings and events All members (devices) have clocks to compare time to an absolute base and scale A destination (position) is targeted for the event A time (timestamp) is set for when the event shall occur A message is sent to each member (device) to meet at a given place at the pre- determined time Not all messages will arrive at precisely the same time… Meeting Conf Rm 2:00 pm Copyright © 2012 Rockwell Automation, Inc.

Why Ethernet? …Is It Capable?
100 Mbps “Fast Ethernet” Delivers raw speed that’s fast enough to handle motion applications Raw data bandwidth can support 100 axes of data in one msec Market moving to Gigabit Ethernet 100Mbps “Fast Ethernet”… ----CLICK---- Delivers raw speed that’s fast enough to handle motion applications. Raw data bandwidth that can support up to 100 axes in 1ms. With the market moving to Gigabit Ethernet, CIP Motion will be able to migrate with improvements to Ethernet and leverage increased bandwidth in the future. The Ethernet wire speed is not the “bottleneck”…most often the “bottleneck” exists at the end devices and not the wire. Copyright © 2012 Rockwell Automation, Inc. All rights reserved.

100 Mbps “Fast Ethernet” Switched Technology QoS Frame Prioritization IEEE-1588 Time Sync Service Proven Industrial Reliability Low Cost per Node (Built-in) QoS Prioritization (DSCP) Message types can be prioritized so that switches handle higher priority messages first Motion, I/O, other QoS or Quality of Service Prioritization (DSCP – Differentiated Services Code Point)… ----CLICK---- Messages types can be prioritized so that switches handle higher priority messages first. Basically, high priority messages…like motion…are serviced before lower priority messages like I/O. This prioritization ensures high priority data is delivered in a timely manor.

Quality of Service Quality of Service (QoS) prioritizes the order in which traffic is sent Utilizes the Differential Services Code Point (DSCP) field in IP header Ensures timely data delivery of high-priority traffic – i.e., PTP messages, Motion, etc… 1588 PTP Messages Ethernet Switch Traffic Type DSCP (Priority) Time Sync 59, 47 (Highest) Motion I/O 31, 43, 47 Other 27 (Lowest) Motion Control Messages We have spent a majority of this presentation discussing many of the components behind how the CIP Sync and PTP maintain time synchronization, let’s briefly discuss one additional topic that helps ensure that all of those time critical PTP messages are delivered in a timely manner. Quality of service or QoS prioritizes the order in which traffic is processed in network switches. QoS helps reduce or minimize network delay. QoS is important as PTP messages are time critical and need to be transmitted with minimal delay. Priority is assigned based on the differential services code point or DSCP field located in the IP header. Let’s take our example above. Let’s say PTP, motion control, distributed I/O, and other device message frames arrive at a switch at the same instance of time. The pink PTP frames have the highest priority or DSCP value and as such will be processed by the switch first. The green motion frames are next, followed by the red I/O and blue other device frames. The main concept of QoS is…whenever possible…to process the highest priority data first. This ensures time critical data is delivered in a timely manner. We will speak more about QoS in another presentation. Distributed I/O Messages Other Devices Messages Copyright © 2012 Rockwell Automation, Inc. All rights reserved.

The CIP Motion Solution
CIP Motion uses standard unmodified Ethernet to handle deficiencies associated with traditional motion control networking solutions The time-slotted approach normally used in traditional motion networks introduces system limitations that have been tolerated as part of any motion networking architecture. These limitations include: Inability to add or remove drives during runtime Inability to obtain additional diagnostic from the drives during runtime Inability to change drive configuration during runtime CIP Motion handles the deficiencies associated with traditional motion control networking solutions. The time-slotted approach normally used in traditional motion networks introduces system limitations that have been tolerated. These limitations include the following runtime restrictions: Inability to add or remove drives. Inability to obtain additional diagnostic or status data from the drives. Inability to change the drive config. Typically, making these type of changes require the network to be “scheduled” offline. Let’s now take a look at how the time-slotted approach works.
