11.3 Setting up a NET
Remote RUN
If this field is enabled, the NET stations of a group with NET-IDs 02 through 08 will take
their current RUN or STOP operating mode from the NET station with NET-ID 1.
Bus delay
The bus delay is used to define the time after which a station on the NET will send its
data to other stations.
This bus delay needs to be adjusted as appropriate for the number of stations and the
values being transmitted. Please note than an excessively short bus delay will result in
data collisions.
The permissible value range for the bus delay is 10 ms to 255 ms.
Cyclical data will be sent every 10 ms or when there is a data change, but not before
the bus delay has elapsed. Using the default value of 60 ms will normally be sufficient to
prevent transmission overloads.
You can use the following formula:
l
Case A: When using PUT/GET and network markers:
Bus delay in ms = (number of NET stations - 1) * 4 * 2 + 6
l
Case B: When using network markers exclusively:
Bus delay in ms = (number of NET stations - 1) * 2 * 2 + 6
The following table can be used as a convenient guide for configuring the setting:

PUT/GET in ms

If you are no longer able to connect to the NET stations via Eth-
ernet with easySoft 7, set the bus delay as high as possible for
your application.
To do this, you will need to disconnect each device from the
Ethernet and use easySoft 7 to change the bus delay point by
point.
