(seechapter“15.20.4Accesstofurtherparameters(cyclicandacyclic)”onpage117 ).
Please note: Thebaudrateofallnetworkparticipants(controlheads,gateway,possiblyotherproducts)
must correspond to each other!
To apply any changes to settings, restart the device!
If the settings are changed by actuating the DIP switches, these changes will not take eect
until the device is restarted! For a restart:
•
triggerarestartcommandviaBürkertCommunicatoror
•brieydisconnectthecontrolheadfromthepowersupplyandreconnector
•switchthepowersupplyo/onor
•transmit an appropriate reset message.
Special characteristics for conguration of the “software congurable baud rate”:
•
Hardwareconguredvalues(viaDIPswitch)havepriorityoversoftwareconguredvalues!
•IftheDIPswitchesweresetto“softwarecongurablebaudrate”,thecurrentbaudrateisstillvalid-
until a new baud rate is selected via software. Then restart the device!
Example: Resetting the factory setting without using the software:
Set DIP7+8 to 500 kbit/s. Restart device.
ThensetDIP7+8to“softwarecongurable”.Restartdevice.
