Which products are affected?
EMF 2171/72IB CAN communication module software version 1.2
How is the reaction?
Sporadically the module gives no answer to a parameter read job / parameter write job (read / write code).
When does the problem occur?
If parameter write job / parameter read job follow one by one via the CAN bus, e. g. when the complete parameter set is transferred with GDC, the module might give no answer to a parameter job.
Possible diagnostics?
If the module does not answer to a parameter job, the above-mentioned problem can be the reason.
Short-term measures / recommendations?
If parameter read job / parameter write job to EMF 2171/72IB follow one by one, a waiting time of at least 1 ms is supposed to be respected.
