SIMATIC Teleservice
Remote maintenance of automation systems
Machines and plants are increasingly operated in places which are far
away from the place of manufacture. Manufacturers of plants must nevertheless be
able to provide support in the event of a fault. Especially during the warranty
period this can result in high costs. TeleService helps to reduce this risk.
Highlights
- Shorter response times for service call-outs
- On-site service call-outs can be reduced by up to 60%
- Easy-to-handle solution, tailored to industrial automation
- Support for SIMATIC-specific services
- Support for PROFIBUS and Ethernet analog networks
The possible applications for TeleService are manifold. Plants can be
diagnosed, values set and data transmitted from any place on earth via a
telephone cable.TeleService contributes significantly to reduce travel and
personnel costs for service calls and has therefore been a standard product in
automation for a long time.
SIMATIC TeleService comprises the following coordinated components:
- TeleService adapter with integral analog or ISDN modem and serial
interface for external modem, e.g. wireless modem
- TeleService software with access data management, enabling user-friendly
establishment of the connection to the automation components
- Function blocks for remote maintenance, remote link, and alarm via SMS or
fax
Application
- Remote maintenance
For remote maintenance a technician dials into a remote plant by
telephone. STEP 7 can be used to read status information or to correct the
user program remotely.
- Remote connection
Remote connections are used to transmit data over the telephone network.
TeleService supports program-controlled connection buildup between the PG or
PC and automation system. Process data exchanges between several automation
systems can also be coordinated..Three types of remote connection are
possible:
- Remote connections to a plant which are initiated by a programming
device or PC, for example, to transmit recipes to a remote plant or to
transmit process or plant files for analysis or processing at a central
office
- Remote connections to the PG or PC initiated by the plant
- Remote connections between two plants for exchanging process data.
- Sending a text message or e-mail from a plant
This function can be used to send text messages by SMS from a plant to a
mobile phone. TeleService can also send the SMS to a provider which then
forwards the message as a fax or e-mail. The TeleService Adapter IE is used to
send e-mails directly.
- Remote access to HMI device
With the TeleService Adapter IE, it is possible to access an HMI device for
remote maintenance. WinCC flexible with Sm@rt- Service/Sm@rtAccess is required
for human machine interfacing. Internet Explorer or the SmartClient option is
used.
