TECHNICAL INNOVATIONS
Smart diagnostic tool
Figure 2 shows " Softing TDX " (Tester
for DiagnostiX), which is a technology
to create and maintain a cloud-based
smart diagnostic tool. The entire tool
chain is based on international standards.
Using TDX Templates, the content
development tools are used to create
TDX content, such as ODX data,
OTX scripts, GUI elements and cloudbased
web services.
TDX supports OBD and UDS on CAN
TOHE Eberspacher Ad 0819.qxp_1/2 Page Island 7/25/19 3:16 PM Page 1
and can be extended to support UDS on IP
(Ethernet) by simply adding another template.
The protocol templates are delivered
as ODX files. Examples of OTX scripts include
flash jobs, guided fault-finding sequences
or procedures that support preventive
and predictive maintenance.
TDX is a technology that supports
vehicle manufacturers and their suppliers
in the development of their own
diagnostic system. Typical users are
manufacturers of electrohydraulic control
systems, electric and hybrid-electric
vehicle (EV and HEV) components,
engines and emissions control systems,
ag tractors, special-purpose vehicles
such as firetrucks, commercial trucks
and buses, as well as motorcycles,
trikes and quads.
Templates cover the most common
use cases such as vehicle/ECUidentification,
fault code management,
handling of measured values and flash
jobs. OTX scripts, business logic and a
GUI proposal are prepared and ready to
be used for all templates.
Bosch Rexroth, a leader in electrohydraulic
systems especially for mobile
machines, has developed the Bosch
Rexroth Digital Application Solution
(BODAS-service 4.x). A TDX-based
flash and service tool for electronic devices,
BODAS supports RC 40 controllers,
directional valves, off-highway inverters
and ultrasonic / radar sensors
from Bosch. Figure 3 shows a screenshot
of BODAS-service 4.x.
The application is internally used by
Bosch Rexroth and externally by customers
for the configuration of
BODAS-ECUs, machine commissioning
and diagnostic testing. Updates are
performed via the Bosch Rexroth
Internet infrastructure.
" We were looking for a scalable, open
diagnostic software for our new BODAS
controllers that would also offer easy
access - in other words, something
that would suit us 100%. And with
Softing TDX, we found the right tool for
that, " said Robert Stawiarski, product
manager tools at Bosch Rexroth AG.
