Iec104sLib libraryTXV 003 62

The Iec104sLib library is used for communication of Tecomat systems with the central unit of the K and L series (all Foxtrot systems, TC700 systems with CP-7004 or CP-7007) with superior systems according to the IEC 870-5-104 standard. In this case, the Tecomat system is a slave of the remote control (it works as a server).
The library contains the function block fbIEC_60870_5_104_s, which implements everything needed for communication. Communication takes place via TCP / IP protocol with destination port 2404. The following ASDUs from the IEC 870-5-104 standard are supported:

Operational information in the direction of tracking

• One-bit information
• Two-bit information
• 32-bit bit string
• Measured value, short floating point number
• One-bit information with time stamp CP56Time2a
• Two-bit information with time stamp CP56Time2a
• 32-bit bit string with time stamp CP56Time2a
• Measured value, short floating point number with time stamp CP56Time2a

Operating information in the control direction

• Simple command
• Double command
• Setup command, 32-bit bit string
• Setting command, measured value, short number with floating point

System information in the direction of tracking

• End of initialization

System information in the direction of control

• Time synchronization command
• Total question
• Read command
