The communication object is enabled when in parameter window
values cyclically has been selected with the option yes. The value of the communication object is sent on a change or when a
telegram is received on the communication object Request status values.
The communication object consists of a mask that defines the valid bits and their data. The data indicates the monitoring faults
of the power values.
If the master does not receive all the external power values from the slaves within the parameterized monitoring time, the
missing values are requested via Value Read and an internal timer starts (10 s). After the timer has timed out, the correspond-
ing error bit is set and the value of the communication object is sent.

This communication object is enabled when in parameter window Function, page 35, the parameter Device is load control
master has been selected with the option yes. The value of the communication object is sent on a change and when a
telegram is received on the communication object Request status values.
The master adds the received power values to Send sum power values (communication object no. 27). If the sum is greater
than the parameterized permitted load limit, the value of the communication object is set to 1 and sent. If the sum is less than
the allowed load limit (minus hysteresis), the value of the communication object is reset to 0.
Function
Status load control
1 = The respective status bit is valid and is evaluated
0 = The respective status bit is invalid and will not be evaluated
1 = Monitoring error, the monitored value has not been received
0 = The monitored value has not been received within the monitoring period
Note
Monitoring of power values 1...4 is only active provided that the corresponding parameter Source for power
value 1...4 has been parameterized with the option external via object and a power value has been
received.
