5. ROCKWELL SOFTWARE PACKAGE
A software package (PLC program) is available that streamlines the engineering time it takes to access the
data and quickly utilize for advanced monitoring scenarios. The software includes:
•
Routines containing an example setup consisting of four message instructions
•
UDT accessible from an HMI containing alarms, status of the SCM, and other info
•
A list of alarm texts that correspond to different alarms
•
Example HMI program to demonstrate PLC code functionality
5.1 ETHERNET IP LINK INITIALIZATION AND MONITORING
The PLC program will automatically read class 3 data upon entering run mode.
The PLC program will monitor communication link and attempt to reestablish if lost.
The PLC program will provide a status message representing the current status of the link. If the
communication status has been lost, it will trigger an alarm in the HMI UDT.
The PLC program will also monitor the On Time values from each of the power supplies. If the time fails
to increment, this means the power supply has lost communication and the PLC will trigger a
corresponding alarm.
5.2 ALARMS (HMI MESSAGE PROVISIONING)
The PLC program will send, monitor, and evaluate alarm and warning conditions from different sources
including the SCM and internal calculations. It will set an appropriate status and write alarm values in the HMI
UDT. An additional text list will associate these alarm values with an alarm text that can be displayed on an HMI
screen. Specific alarm and warning conditions are explained in other sections.
5.3 MESSAGES
There will be four message instructions in the example routine that will interface with the SCM and
PLC program.
5.3.1 MESSAGE GROUP 1: MSG_HARDWARE_PARAMETERS_INITIAL_READ
Upon initialization of communication link, the PLC will read the following class 3 data from the SCM and
write to the HMI UDT:
•
SCM Part Number
•
SCM Serial Number
•
SCM Manufacturer Lot Code
•
SCM Manufacturer Name
