2 Overview Logix5000 Clock Update Tool What is is it? it? How will it it help me? How do do I I use it? it? When can I I get get it? it? 2

3 What Is It? Free-of-charge application that allows you to manually and automatically synchronize controllers wall clock time with PC s time Automatic synchronization can be scheduled at intervals as fast as every minute and as slow as one month Allows for configuration of up to 110 different devices, and up to 3 independent synchronization schedules. Improved version of tool called Chronos Requires RSLinx Classic Lite 3

4 How Will It Help Me? Allows easy and unattended synchronization of devices time Takes care of devices clock drift Need not to worry about daylight saving time or leap year changes It increases the effectiveness of time-stamping Eliminates the need to reset the device s clock after maintenance or power cycle Doesn t require specialty synchronization module in each rack 4

5 Tool Overview Add device Add schedule Remove schedule PC s clock Schedules List of devices Activity Log Time and date when last update occurred Free-running time difference 5

6 Features Allows for Manual synchronization, or up to three independent schedules Uses PC s regional settings for date and time formatting Solves Daylight Savings Time and Leap year issues RSLogix 5000 and firmware version independent Appears on the Custom Tools menu of RSLogix 5000 (v13 and higher) Supports Logix5000 and others devices ControlLogix, CompactLogix, FlexLogix, DriveLogix and GuardLogix MicroLogix 1500, SLC500, PLC5, PowerMonitor II, and PowerMonitor 3000 See on-line help for detailed list of products supported Accuracy is dependent on controller and network load Ability to start when Windows starts, and minimize to the system tray to synchronize devices in the background Leverages RSLinx Classic Lite 6

7 How Do I Use It? Step 1 - Add Devices 7

8 How Do I Use It? Step 2 - Setup a schedule 8

9 Accuracy Actual accuracy will depend on Controller s load, network type, network traffic, and may be affected by the Overhead Time Slice In the tests we administered 99% of readings indicated that the controller and PC were less than 100ms apart 93% of readings indicated that the controller and PC were less than 50ms apart Based on these test results, this tool may not be appropriate for Sequence of Events Applications Time Difference (ms) Time Difference (ms) Accuracy Accuracy Test Test 9

10 Supports for Features Planned for V16 Supports Universal Coordinated Time (UTC) (Formerly known as GMT). Sets Time Zone and Daylight Savings Time based on the user s PC settings Requirements Device to be synchronized and PC must reside in the same time zone. Requires V16 or higher Firmware for new features. Devices with pre-v16 firmware will store the local time, ignoring the time zone and daylight saving time. Note: Users should avoid setting the Time Zone or Daylight Savings Time from RSLogix 5000, as any changes will be overwritten during the next synchronization. 10

11 In Conclusion Allows easy, unattended, time synchronization for Logix5000 controllers and other devices Distributed Free of Charge RSLogix 5000 and Firmware independent. Relies only on RSLinx Classic Lite 11
