Addressing
IQAN-MD4 use of an ID-Tag
In IQANdesign 3.0 and higher software, more than one IQAN master module can be
used together in a multi-master system. The master modules are each given a unique
address by using an ID-Tag. The value of the ID-Tag identifies the master and will
enable a single project application to be loaded into more than one master module over
the CAN bus. The functionality needed for each master is loaded based on the ID-tag
address.
Identification of an IQAN-MD4 by address
For normal operation of an IQAN-MD4 in a single master system, the ID-Tag is still
used. When no ID-Tag is installed, the MD4 will start in safe mode.
The connection of an ID-Tag between ADDR-H and ADDR-L will assign an address to
the IQAN-MD4 master module. The desired functionality based on address is built into
the project file using IQANdesign software. For more information, please refer to the
IQANdesign user manual. It is the combination of address and module type that gives
each master module a unique identification.
