Diagnostic interfaces
IQAN software includes many tools for tuning, measuring, accessing logs and
otherwise checking the performance or troubleshooting your control system. To use the
diagnostic tools with an IQAN master module you may choose between different ways
to connect to the unit.
CAN diagnostics connection
One of the CAN buses of the IQAN master module may be dedicated for diagnostics.
Reserving a bus for diagnostics ensures that signals are not interrupted by other bus
traffic. A high-speed CAN interface is needed to use this feature. Contact Parker for
information about supported CAN interfaces.
A termination resistor is usually required at the CAN interface on the PC. Parker part
number 5030082 or 5030182, or an equivalent 120 ohm resistor may be used. A flying
lead cable may be connected to the IQAN master to provide a connector interface. The
connection from IQAN master module to diagnostic CAN interface can then be made
quite easily. It is recommended that the connector be a sealed, automotive type. When
not being used this connector should be protected from the environment with a cover or
mating blank plug.
The recommended wiring to the IQAN master module connector is shown below.
