Using Sample RSLogix 5000 Projects with the
Sequence of Events Module
Overview Rockwell Automation offers several sample RSLogix 5000 projects to
use with your Sequence of Events module. The module timestamps
input transitions and provides that data to its owner-controller.
However, you must use the data to perform such tasks as:
• detect relative first faults
• determine absolute first faults
• associate real-time with CST-formatted timestamps
Table E.1 describes the sample projects Rockwell Automation offers:
To access the sample projects, see page E-2.
Table E.1
Project: Description:
GPS_withSOE.ACD This project uses multiple user-defined data types (UDTs) and one subroutine.
The project provides samples on how to manage and buffer information from a 1756HP-GPS module.
Many of these messages are optional and dependent on how you implement your specific system.
The last rung of this routine provides the interface for communications between the ControlLogix
Sequence of Events module and 1756HP-GPS module so the Sequence of Events module will return UTC
time instead of CST.
SOE_Module_FifoExtract.ACD This project uses multiple user-defined data types (UDTs) and subroutines.
The project is an example of extracting data from an Sequence of Events module system (multiple
modules), with the following constraints:
• The modules operate in FIFO mode.
• The controller uses Standard Retrieval to retrieve timestamp data from multiple Sequence of
Events modules.
• Sample of sorting multiple timestamps
ST_BubbleSort.ACD This project uses two Structured Text subtroutines.
The project is an example of easily sorting data.
IMPORTANT
Table E.1 only briefly describes the sample projects.
The projects have rung-by-rung descriptions to
explain why the projects were written as they were.
We recommend you open the projects to see exactly
how they were written and how to use them.
