Security Considerations
A controller or application does not need to log in to read real-time metering,
configuration, and status data from a PowerMonitor 5000 unit, whether security
is disabled or enabled.
If security is enabled, a controller must log in under an Application account class
to perform the following:
• Write configuration or commands
• Read log data
To log in, write the username to the Security.Username table. Within 30 seconds,
write the password to the Security.Password table. In the source data, buffer the
username and password with null characters so the string length is 32 bytes.
A read of the Status.TableWrites table verifies success of the login and indicate
which account class is active. A login remains active until 30 minutes have elapsed
since the last write message.
Examples: Explicit Message
Setup Refer to the following examples for details about setting up an explicit message.
RSLogix 5000 Software – PLC-5 or SLC Typed Read Message Setup
The following is an example of a message instruction to read single or multiple
elements from a PowerMonitor 5000 unit by using PLC-5 or SLC Typed
messages. This setup applies to ControlLogix and CompactLogix™
programmable logic controllers.
After setting up a message instruction, open the message configuration dialog
box. The Configuration tab is selected initially.
TIP The Studio 5000™ Engineering and Design Environment combines engineering
and design elements into a common environment. The first element in the
Studio 5000 environment is the Logix Designer application. The Logix Designer
application is the rebranding of RSLogix™ 5000 software.
