The meaning of the status bits is determined as follows:
6.2.1.2
PDO_2
PDO_2 is sent with identifier 0x280 + node address. It contains exactly four 16bit
words (left-aligned) in the order Us1, Ud1, Us2, Ud2. The synchronous identifier which
is up to be received is 0x80. It can be read in index [1005,00].
The values transmitted in PDO_2 are based on the values shown in the status line of
the monitor program but are converted according to the following schema:
Bit no.
Value
Meaning
7
0x80
Us1 exceeds chosen threshold for channel 1
6
0x40
Us2 exceeds chosen threshold for channel 2
5
0x20
Toggle-Bit, changes its status after each transmission of PDO_1
4
0x10
calibration is active
3
0x08
DC monitoring Ud1 is OK
2
0x04
DC monitoring Ud2 is OK
1
0x02
not connected
0
0x01
Checksum of the EEprom - parameter is wrong.
