Electromagnetic compatibility
Definition
Electromagnetic compatibility is the ability of an electric device to function
satisfactorily in its electromagnetic environment without interfering with this
environment.
The ET 200X distributed I/O device complies with the requirements of the EMC
legislation of the European internal market. A requirement for this is that the ET
200 distributed I/O system meets the specifications and directives concerning
electrical installation.
Bus parameter settings for the PROFIBUS-DP
Note
To maintain the EMC values, you must increase the ”Retry Limit” bus parameter to
at leas ”3” in your configuration software (e.g. COM PROFIBUS or STEP 7) for
transmission rates of 500 kbps and 1.5 Mbps. Leave all the other bus
parameters as they are, in accordance with your selected bus profile.
Pulse-shaped interference
