The IEC 60870-5-104, Slave implements the controlled station functionality specified in the IEC 60870-5-104 protocol. The implementation corresponds to the IEC 60870-5-104 second edition 2006-6. It has been exhaustively tested and certified to comply with the standard by KEMA. See below for the testing certificate and and report.

The IEC 60870-5-104, Slave protocol stack offers almost the full functional range of the IEC 60870-5-104 protocol. The supported features:

Simultaneous and independent communication with several control stations through the same port

Communication with redundant control systems and interruption-free switchover between redundant systems

Supports redundant networks

Bi-directional data transmission&xnbsp; (B marking in the interoperability list), this means that indications, measured values, commands etc. can be transmitted in both directions – from control station (master) to slave and vice versa

Supports “select before operate“ or “direct execute“ command execution modes

Largely supports RTUs that do not fully comply with the second edition of the IEC 60870-5-104 standard
