baud rate at which the data is exchanged, the total time required may exceed the
set interval. Then it is no longer possible to keep the polling cycle. With MBus
meters, all data points are sent during the polling, even if only a few have been
set up. Differently with Modbus or system counters it is only the data points that
have been set up.
Approximately can be assumed for MBus counters:
At 300 bit/s, 10 counters per minute can be queried.
At 2400 bit/s: 48 counters per minute can be queried.
At 9600 bit/s: 60 counters per minute can be polled.
An approximate value can be assumed for Modbus counters:
At 300 bit/s: 60 counters per minute can be polled.
At 2400 bit/s: the maximum number of 247 counters per minute can be polled.
The time required for system counters can be neglected.
For counters with large data packets with multi-response, each data packet must
be evaluated as one counter for the time calculation.
With the MBus a mixture of different baud rates is permissible. Accordingly, the
individual times add up to the total time.
Press the "+" or "-" action field to open and close the counter field by the expert parameters.
