The devices of the RTU3000C family are compact telecontrol stations. They enable connection of remote measuring points to TeleControl Server Basic or another control center and monitoring of these measuring points. To ensure autonomous operation the devices can also switch between four different operating modes: - Sleep mode All inputs and communication functions are turned off so that energy consumption is minimal. Outputs can retain their last value.
- Update mode Used to query the inputs and outputs. The query cycle can be configured individually.
- Communication mode Mobile wireless connection or connection via LAN interface and external router and communication to the central office are active.
- Service mode
Maintenance work can take place without loss of data.
Connection of the SIMATIC RTU3030C to TeleControl Server Basic Energy-independent mode The RTU3000C stations can be operated in energy saving mode. Depending on the communication requirements and the connected type of power supply (e.g. battery, solar accumulator), independent operation can thus be guaranteed for many years to come. Data backup Data losses are prevented by the data buffering mechanisms integrated in the product. In the event of a connection failure, time-stamped frames are buffered in the device. When the connection returns, the buffered values are automatically transferred to the control center in the right order. Data logging The RTU3000C stations support the backup of process data on SD card. The retentively saved data can be sent cyclically by email and/or FTP or, if necessary, be downloaded directly using web-based management (WBM). Data logging on SD card Data point configuration For data point configuration, the RTUs supports a series of data point types: Digital input, digital output, analog input, counter input. The data points can be configured with little effort using the web pages of the RTU3000C stations. A cyclic and/or event-controller transfer of measured values, setpoints or alarms can thus be implemented in only a few operations. Data preprocessing Ready-to-use program blocks enable data preprocessing directly in the RTU. The process data can be linked by means of process blocks for basic control jobs. Use of analog and digital bit memories enables buffering of calculation results. 38 different types are supported in the following groups: - Blocks for logical functions (e.g. AND, OR)
- Blocks for time functions (e.g. ON and OFF delay, astronomical clock)
- Blocks for analog value functions (e.g. threshold value monitoring)
- Counter blocks
- Blocks for messages (text messages, email)
- Block for FTP file transfer
- Relay blocks (latching relay, pulse relay)
- Blocks for silo volume calculation
- Block for rectangular weir overflow calculation
Time synchronization The RTUs support time synchronization and therefore ensure that historical data is given the correct time stamp. In addition to using the NTP protocol, you can synchronize the time via the telecontrol center or, in the case of RTU3030C, via the mobile wireless provider. Alarms sent by email or text message For timely communication of station statuses to service and maintenance personnel, alarm emails or, in the case of RTU3030C, alarm text messages can be configured. When previously defined events (such as threshold violation) occur, application-specific information is sent automatically by email or SMS (directly or via the connected router). Telecontrol communication using standard protocols For communication with the control center, the RTUs support the DNP3, IEC 60870-5-104 and SINAUT ST7 telecontrol protocols. The RTUs act as a DNP3 station or as an IEC slave or, in the case of SINAUT ST7, as a station connected to an ST7 node station, e.g. TIM 1531 IRC or ST7 control center. The RTUs can also be connected to the TeleControl Server Basic (TCSB). TCSB enables a connection to any control center software, e.g. WinCC OA over OPC UA. Remote maintenance The RTU3000C stations provide remote maintenance access via WBM for access from the control center. The RTU3030C can be woken from sleep mode via text message or a phone call. When using the "TeleControl Basic" communication protocol, the wake-up text message can be generated in the CMT of TCSB. Alternatively, a wake-up test message can be initiated when SINEMA Remote Connect (V1.3 or higher) is used. Security mechanisms Access to the RTU3000C stations requires an authorization. Up to 20 different authorized email addresses or phone numbers can be defined in the WBM. Data is sent through an OpenVPN tunnel (for RTU3030C only) or the secure tunnel of the TeleControl Server Basic. Email messages can be encrypted (support of STARTTLS). FTP uploads can be carried out as encrypted uploads via SSL with FTPS. Diagnostics The RTU3000C provides comprehensive diagnostic options for a quick and informative analysis of the station status. Basic diagnostic information, such as the status of the power supply, the communication connection and the inputs and outputs are signaled directly to the RTU by LEDs. The current status of the LEDs can also be retrieved through WBM. Using the web server, comprehensive information can be retrieved, such as facts about the connection history, buffer status, and the transferred measured values. Configuration over web server The integrated web server is accessed locally for diagnostics from a PC or remotely via the mobile wireless interface or Ethernet interface with upstream industrial router. Configuration, firmware update or configuration changes can therefore be performed remotely without additional software thereby saving time and money.
