Station statuses 1 to 3
Definition
Stations status 1 to 3 provides an overview of the status of a DP slave.
Station status 1
Table 6-16
Structure of station status 1 (Byte 0)
Bit
Meaning
Cause/remedy
0
1: The DP slave cannot be accessed by
the DP master. The bit on the DP slave is
always "0".
● Correct PROFIBUS address set on the DP
slave?
● Bus connector connected?
● Voltage on the DP slave?
● RS 485 reporter properly set?
● RESET (switching off/on) performed on
DP slave?
1
1: DP slave is not ready for data ex‐
change.
● Wait, as DP is currently starting up.
2
1: The configuration data sent by the DP
master to the DP slave does not match
the configuration of the DP slave.
DP slave is OK, but the configuration does not
match the actual configuration of the slave.
Compare the preset configuration with the ac‐
tual configuration.
Note:
If the last slot is not occupied, a slot cover must
be installed! This is in the terminating module.
3
1: There is external diagnostic informa‐
tion.
Evaluate the identifier-related, the module sta‐
tus and/or the channel-related diagnostics.
When all errors are eliminated, bit 3 is reset.
The bit is reset if there is a new diagnostic
message in the bytes of the previously men‐
tioned diagnostics.
