Parameterization of the CM579-ETHCAT Communication Module Interface

Double-click on CM579_ECAT (CM579-ECAT) to open the CM579-ECAT Configuration in the editor window:

The following parameters are available:

Parameter	Default value	Value	Meaning
Run on config fault	No	No	In case of a configuration error, the user program is not started.
		Yes	The user program is started independent of a faulty configuration of the EtherCAT® Communication Module.
Max wait run	3000	3000	Maximum wait time for the Master to build up the communication relation to the slaves. A restart to build up the communication is initiated as long as BootUpTime has not run out.
Min update time	10	0…20000	Priority of the data exchange between CPU and Communication Module. This parameter should never be set to values under 10, otherwise important sequences in the CPU might be influenced.
Bus cycle time	5000	500…5000	Bus cycle time in [µs].
Broken slave behavior	Leave all broken slaves down	Leave all broken slaves down	Broken slaves will not be served.
		Leave addressless slaves down	Only slaves without address will be left down.
		Leave no slaves down	Broken slaves will be ignored.
Distributed clocks	Inaktiv	Inactive	Distributed clocks are inactive.
		Active	Distributed clocks are active.
BootUpTime	10000	10000	Maximum wait time for the slaves to boot completely. This absolute time value must be a multiple of Max wait run. It defines the time in which Max wait run is restarted to wait for the slaves to boot up completely. The multiplication ratio between Max wait run and BootUpTime can be interpreted as number of trials to boot up the slaves.
