Cash-in-transit Vehicle
ocation: England, United Kingdom
Product: I-7530-FT
Description: A telematics and vehicle control system
need to be closely integrated with each other by
implementing data exchange interface. LSFT (Low
Speed/Fault Tolerance) CAN is a familiar type of
interface in the application of automotive electronics
systems. The I-7530-FT is specially designed for
solving the problem of interface transformation
between LSFT CAN and RS-232. In this way, the
cash-in-transit of the manufacturer can efficiently
control the door of the cash safe and directly monitor
the status of the rear access vehicle door on the
telematics.
IC Inspection Machine
Location: Hsinchu, Taiwan
Product: PISO-DNS100U
Description: The IC inspection process is necessary
for good quality control. Though PLCs are cheap
and stable, IC inspection is a diffi cult task for a PLC.
The user uses a PC plus a camera together with a
PISO-DNS100U to perform the IC inspection, and
uses a PLC to control the mechanism used to reject
defective ICs. After completing the inspection, the
PC writes the result to the PISO-DNS100U. Because
the PLC is used as a DeviceNet master, it can easily
retrieve the information from the PISO-DNS100U via
the DeviceNet network.
MRI Cooling System
Location: China
Product: I-7232D
Description: In order to reduce costs, an MRI
manufacturer uses a chiller made in China instead
of a more expensive German product. However, the
user experienced difficulties due to the different
communication interfaces. By using the I-7232D, this
problem was solved. The I-7232D was able to be used
as a Modbus RTU master while communicating with
the chiller. In contrast, in the CANopen network, the
I-7232D can be used as a CANopen slave. As a result,
the I-7232D is able to easily pass information from
the chiller to the CANopen master, and cconversely
transfer CANopen commands to the chiller.
CAN Bus Repeater/Bridge/Switch
The CAN Bus Repeater/Bridge/Switch is used to enhance the signal quality, extend the communication distance, isolate CAN
bus network. ICP DAS provides following products.
