QTester104 – IEC 60870-5-104 protocol tester.

This software implements the IEC60870-5-104 protocol for substation data acquisition and control via tcp/ip network using the QT UI Framework. Can be compiled on Linux and Windows platforms. It’s possible to view and poll data from the substation system (RTU/concentrator) and also send command.

Platform : Windows & Linux

  • Provided win32 binaries.
  • Poll substation data.
  • Send commands.
  • Classes structured to easily integrate with other systems.
  • Useful to develop protocol translators.
Read me :
qtester104src – multiplatform qt sources, compile with QT 4.7 or later on any supported platform.
qtester104bin – win32 binaries built with QT 4.7.0.
Can be used to poll substation data and issuing commands.
The base protocol classes are pure C++ without any platform or non-standard library dependancy, can be used to develop software with other compiler/library/sdk.
The software is part of a full substation HMI project (planned to be released eventually), it functions as a protocol module for the HMI, but can be used as a standalone protocol tester.
It’s possible to send a General Interrogation ([GI] button) and log messages on the screen.
At the right panel is shown a table with the following data columns:
Protocol [Address] | Last acquired [Value] | ASDU [Type] | [Cause] of transmission | Quality [Flags] | [Count] of transmissions.
The protocol quality flags are:
on / off / tra (double point transition) / ind (double point indefinite) / bl (blocked) / iv (invalid) / nt (not topical) / sb (substituted) / ov (overflow) / t (reg.step transition).
An optional configuration file can be used to store basic parameters, in the form of a INI file (qtester104.ini):
PRIMARY_ADDRESS=1        ; link address of the primary station (computer)
[RTU1]                   ; communicates with only one RTU in this version
SECONDARY_ADDRESS=1      ; protocol link address of the RTU
IP_ADDRESS=   ; IP address of the RTU
ALLOW_COMMANDS=1         ; 1=allow sending commands, 0=don’t permit commands
