2.1.2 Master Module
The Master Module is the central processing unit. Its functionality is provided by means of a
loadable and parameter-settable firmware.
The Master Module integrates the function packages for the telecontrol function (spontaneous
processing and communication) and the open-/closed-loop control function (periodical pro-
cessing and peripheral functions) into one common device.
Additionally, it serves as centrally coordinating element for all system services.
Features
• Data node functionality
• Organization of the data flow from and to the communication interfaces
─ Ethernet (TCP/IP) for LAN/WAN connections according to IEC 60870-5-104
─ RS-232 for multi-point, point-to-point or dial-up traffic according to IEC 60870-5-101
with supply for an external transmission facility
─ RS-485 for multi-point traffic
• Main focus in telecontrol
─ Parameter-settable telecontrol function according to IEC 61131-3
─ Parameter-settable communication protocols
─ Time management and time synchronization via SNTP (Simple Network Time Protocol)
− Up to 4 different NTP servers (redundancy)
− Cyclical, can be set in a seconds grid, self-adapting
─ Monitoring and simulation of process signals
• Automation
─ Freely programmable open-/closed-loop control function
─ Deterministic behavior of the open-/closed-loop control function with guaranteed reaction
times and thereby time-consistent
─ Test and diagnosis of the open-/closed-loop control function
• Autonomous behavior (for instance in the case of communication failure)
• Logging and display of events and alarms
• Decentralized archive (DEAR) for the avoidance of data loss during communication fault
• Loadable firmware
• Storage of application data and firmware on SD card
