bit 0 in the Consumed Data to the same value as that of bit 0 in the
Produced Data.
If no bit synchronization takes place, the operating device displays the
error message Timeout Error: Code 60, Subcode1“.
Bit1 to bit7 Bits 1 to 7 are reserved.
Byte 3 and Byte 4 - Word Address
Bytes 3 and 4 in the Produced Data contain the word address starting
from which a variable has changed. The variable can be several bytes
long. The controller uses this word address to selectively read the
changed variable from the data memory of the operating device.
Byte 5 - Number of Bytes
Byte 5 in the Produced Data contains the number of bytes as the size
information for the changed variable.
6.6.2.3 Module /Network Status
The operating devices are not equipped with diagnostic LEDs for
DeviceNet status indication.
To indicate the module/network status, use the system variable Com-
BaudrateA instead.
If the controller detects that bit 0 in the Produced Data and bit 0 in the
Consumed Data differ, bit 0 in the Consumed Data must be set to the
same value as that of bit 0 in the Produced Data!
This also applies if cyclic data exchange is used.
See chapter „ComBaudrateA“ on page 5-49.
