Three New Products for Remote Access by Mobile Radio
Siemens Industry continues to expand its TeleService and Telecontrol product portfolio with the addition of three products for remote access by mobile radio: the CP 1242-7 communications processor module, Telecontrol Server Basic Control call center software, and the IE Basic TeleService Adapter.
The CP 1242-7 communications processor module adds a GSM/GPRS interface to the Siemens S7-1200 controller. “This new module enables plant operators to cost effectively diagnose, maintain, monitor, and control remote stations throughout the world via GPRS and the Internet,” says Brian Shebs, product manager, Micro-Automation, at Siemens Industry.
Easy to operate, the CP 1242-7 is run via a mobile radio contract with a SIM or a special M2M contract. While in service, the module informs personnel via short message service (SMS) of the plant status, including any faults that have occurred. It also opens up remote access via the Internet, which is provided by a computer with Internet access and Step 7 V11 software. A further application for this module is M2M communications, in which physically separated plants are connected with one another, and their processes coordinated.
Telecontrol Basic Control call center software serves as an OPC server for the Simatic S7-200 and Simatic S7-1200 controllers linked via a radio network. This enables data from up to 5,000 connected stations to be brought together and made available via an OPC interface to HMI or SCADA systems. Application examples include the continuous data exchange and central monitoring of widely branched infrastructure facilities, such as water supply systems, wastewater systems, and other utilities. According to Shebs, one system integrator can operate an OPC server for multiple customers.
The IE Basic TeleService Adapter is the third product being introduced for this market segment. It may be fitted with a TeleService GSM module to enable wireless access via a GSM dial-up to a Simatic S7 controller, or to another subscriber with an Ethernet interface. “Mobile radio is increasingly important for remote automation access applications because it is more flexible—and frequently less expensive—than cable-connected systems,” says Shebs.
The worldwide GSM network provides the basis for various data transfer services in industrial automation. Data is transferred with circuit switched data (CSD) by setting up a dial-up connection via the mobile radio network. With SMS, messages are sent to personnel in the form of short text messages. GPRS enhances the ability to set up mobile Internet connections for data transfer.
“These new products add to one of the industry’s broadest product offerings, and underscore our commitment to provide solutions for TeleService and Telecontrol via mobile radio,” Shebs concludes.
