The OTS systems are configured by an attached PC or Notebook. In normal operation the OTS works independently and can communicate events in the simplest case using relay outputs. The number of integrated outputs amounts to 10 and can be extended up to 20. The OTS system is basically equipped with an RS232 interface, through which status, alarm or temperature data can be transferred to PC or PLC systems.
Furthermore, the OTS controller can be equipped with an Ethernet interface. Hereby, the evaluation unit communicates as a TCP /IP server with several clients.
Features of the embedded communication module of the OTS controller:
- Configuration and operation of the OTS via two independent channels:
- Onboard storage of measurement data
- Buffers up to 72 hours of measurement data and initiates data transfer automatically after communication link was re-established
- Individual file access to measurement data through CHARON_02 (onboard data storage 1 GB)
- Allows to operate individual Plug-In-Interfaces for customer specific protocol solutions
- The OTS can communicate in parallel with its proprietary protocol and one or more customer specific protocols like DNP3, IEC60870-5-104, IEC61850, POSC WITSML, Modbus (Master/Slave) etc.
- Individual assignments for protocols and client addresses (IP) possible
- Ethernet communication to and from clients with high bandwidth
- Module comes with built-in user configurable Firewall and enables reliable operation even in WAN’s
- Secure data transmission and individual authorisation according TLS- Standard (RFC 2246)
