Description

Health time out
|
The Health time out zone is used to adjust the health "time-out" value. The value is from 50 to 15 000 ms in increments of 50 ms.
An associated status bit (%IW topological objects between %IWr.m.c.5 and %IWr.m.c.8) is linked to each Global Data item and is used to monitor whether the data has been published and received by the end of the time indicated in this window. If yes, the value is 1, otherwise the bit is set to 0.

Group address
|
The Group address indicates the multicast IP address (class D) of the distribution group to which the station belongs:
|
|
Distribution period
|
The Distribution period zone is used to select the distribution period of the publication. The publication is time-based and is not synchronized with the PLC master task.
The distribution value is multiplied by 10, so the available parameter range of 1 to 1500 represents distribution periods between 10 and 15 000 ms (in increments of 10).
NOTE: With a small distribution period, it is needed to check if the switch connected to the BMX NOE module is able to manage a such amount of frames. Otherwise the switch will send back broadcast frames and the BMX NOE will go in error to cut the data flow. |

Group name
|
The Group name is defined in the Control Expert data editor. The name associates a variable from the variable editor with a particular module.

|
Filtering can reduce data flow on large networks. Multicast filtering requires the use of switches that support this function (GMRP IEEE 802.1D protocol). The status of the check box indicates:
