Message Import Text Files

Release 2.18 and later allows import of message data from text files, usually with a .txt file
extension.
The ASE2000 V2 must be licensed. While data captured by a licensed ASE2000 V2 and saved to
a MSGX file can be loaded and read by an unlicensed ASE2000 V2 or by the free ASE Message
Viewer utility, text file import is a licensed feature only.
To import message data from a text file:
• Exchange Mode: File menu  Select Protocol, choose the applicable protocol
• Task Mode: Select or create a device for the applicable protocol
• It is recommended to choose Monitor mode so that filters for both master and remote can be
entered as described in the next bullet. Import may work in some, but not all, cases from other
modes
• Open the file: File menu  Import  Communication Messages
• From the pull-down list in the bottom right corner of the file open menu, set the type to Text
Message Files
• Locate and open the file
The text file will be opened with data applicable to the selected protocol extracted and shown
in the line monitor and messages views the same as if the ASE2000 V2 had detected those
messages in a normal communication session.

6.3.1. Text Message File Structure

Data in the text file must comply with the following requirements to be successfully parsed into
protocol message data.
• Direction Indicator – Master to Slave: '>' character must proceed data bytes
• Direction Indicator – Slave to Master: '<' character must proceed data bytes
• Time Stamp – Time (if present): must be enclosed within '[' and ']' characters and must comply
with ISO 8601 format. This is a time zone independent date and time representation
• Data stream – Data is a sequence of hexadecimal bytes separated by space characters. Bit
protocol data may be parsed if expressed as if it was received by ASE hardware

6.3.2. DNP3 Example

Here is a text file data example for the DNP3 protocol.
