Table of Maximum Load Rates
The current load is computed dynamically.
NOTE: The loads are dependent on controller scan time. Each application has an
expected scan time. Therefore, when evaluating the loads, you should ensure that
the controller scan time is set to the expected scan time for the application being
modelled.
Enhanced Web Diagnostics
NOTE: These services are available on the 140NOE771x1 modules.
The embedded Web server provides Web pages that you may use to diagnose
Transparent Factory / Real Time services.
Those diagnostic services are listed below:
1. Global Data diagnostics
z Status of all Global Data services
z Status of all subscribed and published variables
z Publication / Subscription rate
2. I/O Scanning diagnostics
z Status of all I/O Scanning services
z Status of individual scanned devices
z Actual I/O scanning rate
3. Messaging diagnostics
z Diagnostic information for Port 502 messaging
4. Bandwidth Monitoring
z Throughput measurement of NOE by service
NOTE: All these pages are protected by the general HTTP password.
