Overview
Teleservice (remote diagnostics and remote maintenance)
Teleservice is data exchange with physically remote technical
plants (machines, plants, computers, etc.) for the purpose
of error detection, diagnostics, maintenance, repair, or optimiza-
tion.
Machines and plants are increasingly operated in places which
are far away from the supplier's premises. Despite this, plant
builders must offer services to deal with faults or for preventive
maintenance. During the warranty period in particular this can
result in high costs. Teleservice helps to reduce this risk
significantly.
There is a variety of possible applications for Teleservice. Plants
can be diagnosed, values set and data transmitted from any-
where in the world via a telephone cable. Teleservice also
enables the SIMATIC controllers to send text messages per SMS
or e-mail, making a significant contribution to saving travel and
personnel costs in service work.
Teleservice via IP-based networks
Optimum remote maintenance is based on reliable, permanently
available, secured and economical data connections.
Depending on the application, SIMATIC NET provides the ap-
propriate solution:
•
For continuous connections or simultaneous access to several
plants, a solution using the SCALANCE S and SCALANCE M
security and communication components is recommended,
both on the service and the plant side.
•
For flexible access for remote maintenance from any Internet
connection - whether in the office, home office or hotel room –
SOFTNET Security Client is the right software solution for
establishing a secure connection to the plants.
•
For plants without a wired network connection, the
SCALANCE M wireless router establishes remote mainte-
nance access to the SCALANCE S in the service center.
In all cases, the communication is reliably protected by
authentication and encryption via a VPN tunnel (

outside.
