Precise object detection under extreme conditions
Ultrasonic sensors transmit and receive sound waves in the ultrasonic range. The object
to be detected reflects the sound waves and the distance information is determined via
time of flight measurement. As opposed to photoelectric sensors, colour, transparency or
the object’s surface shine do not play a role. Blister packages in packaging technology or
transparent plastic bowls in the food industry, for example, can be reliably detected. The
ifm ultrasonic sensors in M18 design provide a particularly small blind zone and long sens-
ing ranges which are usually only achieved by sensors of a considerably larger design. The
sensors operate reliably with heavy soiling so that they can be used in applications in which
photoelectric sensors meet their limits.

PROFINET added to safety controllers
Banner Engineering, locally represented by RET Automation Controls ,
has added PROFINET communication to their popular SC26-2 and XS26-2
safety controllers. The SC26-2 is a versatile, easy-to-use, and configurable
safety controller used to monitor multiple safety and non-safety input de-
vices, providing safe stop and start functions for machines with hazardous
motion. The XS26-2 is a scalable version of the SC26-2 capable of sup-
porting up to eight expansion I/O modules. The addition of the PROFINET
industrial protocol to these safety controllers enables simple and robust
communication channels to any connected devices that use the PROF-
INET standard, including devices from other manufacturers. This new
functionality matches the capabilities available for EtherNet/IP, Modbus/
TCP or PCCC.
“Both the SC26-2 and the XS26-2 were designed to be adaptable to di-
verse and changing automation requirements and to simplify the manage-
ment of complex safety systems,” said Tom McMonagle, Senior Director
of Product Planning at Banner Engineering. “PROFINET communication
builds on this versatility and ease-of-use by facilitating the integration of
PROFINET-enabled peripheral devices into a safety system and by estab-
lishing a high-speed communication link between devices for real-time ac-
cess to system data and diagnostics, which can reduce and even prevent
unplanned downtime.”
These models can be configured with up to 256 virtual status outputs
which can be used to send non-safety status signals to programmable
logic controllers (PLCs), indicator lights, and similar devices.
