Communication options with TeleControl Basic

Process data communication

The TeleControl Server Basic software enables the connection of up to 5000 telecontrol stations to the control center via the OPC interface using mobile radio or Ethernet/the Internet (OPC DCOM and OPC UA).

TeleControl Server Basic is an OPC server software with special communications functions, which permit it to support connections to remote telecontrol substations. These controls are equipped with the CP 1243-7 LTE, CP 1242-7 GPRS, CP 1243-1 (Ethernet), CP 1542SP-1 IRC (Ethernet), the MODEM MD720, or they comprise the compact SIMATIC RTU3030C telecontrol unit. Mobile radio services or standard IP services via Ethernet are used for the connections.

Via the mobile radio connections or Ethernet/the Internet, the remote telecontrol substations can communicate with the TeleControl Server Basic software or with other SIMATIC controllers that are connected with TeleControl Server Basic

The PC on which TeleControl Server Basic is installed must be permanently accessible from the mobile radio network. It must therefore be directly connected to the mobile radio provider using a dedicated line, and permanently to the Internet, e.g. by means of DSL.

The TeleControl Basic software package includes a block library for the SIMATIC S7-200 controller. With the help of these blocks, users can implement data exchange with S7-200 substations.

For substations of the type S7-1200 and ET200SP, the telecontrol functions are configured directly with STEP 7 Basic/Professional V14 (TIA Portal) or higher. The RTU3030C is configured via a web server (Web based Management / WBM).

Alarms as text messages

The communications processors CP 1243-7 LTE, CP 1242-7 GPRS and the RTU3030C can receive and send messages directly as text messages. A mobile phone or another controller can be the communication partner. The CP 1242-7 can receive and send text messages. A mobile phone or S7-1200 can be the communication partner.

Wake-up function

"Wake-up" of stations that change from standby mode to online mode for diagnostics purposes. The CPs are woken up by their communication partner, e.g. TeleControl Server Basic, by means of a wake-up call or a wake-up text message to establish the connection between them.

For security reasons, the communication partner must identify itself appropriately for the wake-up function, e.g. using the CLIP function.

Access to the telecontrol stations using teleservice

TeleControl Server Basic contains the teleservice function directly in STEP 7 V14. This gives internationally active plant and machine manufacturers worldwide access to the SIMATIC telecontrol stations.

Up to three telephone numbers can be saved on MODEM MD720, from which a teleservice connection is permissible. If a call is made from one of the approved numbers, the MODEM MD720 interrupts the GPRS connection and switches through the teleservice connection to the PLC. The GPRS connection is reestablished at the end of the teleservice session.
