Structure of the station status 1(byte 0) ET 200eco

Bit Meaning
0 1: The DP master can not access the
DP slave.
This bit is always "0" on the DP
slave.
1 1: The DP slave is not ready to ex-
change data.
2 1: Configuration data sent to the DP
slave by the DP master is incompa-
tible to the physical structure of the
DP slave.
3 0: The bit is always "0".
4 1: The DP slave does not support the
requested function (e.g.
SYNC/FREEZE).
5 1: When the station status is being
read from the DP master, is the bit

Cause / Remedy
•
Is the correct PROFIBUS address set on
the DP slave?
•
Is the bus connector plugged in?
•
Is the power supply to the DP slave
switched on?
•
Correct setup of the RS485 repeater?
•
A RESET was performed on the DP slave
(off/on)?
•
Wait, the DP slave is currently starting up.
•
Has the correct station type or configuration
of the DP slave been entered in the
configuration software?
–––
•
Check the configuration.
The DP master is unable to interpret the DP
slave's answer.
•
Compare the program and the actual setup.
•
The bit is always 1 when you access the DP
slave from a PG or other DP master, for
example.
The PROFIBUS address of the DP master
that has assigned the DP slave parameters
is found in the diagnostic byte "Master
PROFIBUS address".
