Status 1 and status 2 information
The status 1 and status 2 information is stored diagnostic information generated in a DP-Slave and relevant bits turned on.
The following table shows the description of each bit, actions to take, and stations to detect diagnostic information.
Item
Bit
Description
Action
Detected in
Status 1
b8
Data exchange with a DP-Slave failed.
Check the status of the DP-Slave and PROFIBUS line.
Check the relevant parameters.
DP-Master
b9
A DP-Slave is not ready for data
exchange.
■
When data exchange starts
The station is in normal operation. (This bit turns on every time
when data exchange starts.)
■
When data are being exchanged.
Check the status of the DP-Slave and PROFIBUS line.
DP-Slave
b10
The I/O bytes parameter received from the
DP-Master does not match that of a DP-
Slave.
Check the relevant parameters of the DP-Slave.
DP-Slave
b11
Extended diagnostic information exists.
Check the status of the DP-Slave.
DP-Master
b12
The function requested by the DP-Master
is not supported.
Check that the DP-Slave supports the global control function.
Check the specifications of the DP-Slave.
DP-Slave
b13
An invalid response from a DP-Slave.
Check the status of the DP-Slave or that of the network.
DP-Master
b14
An invalid parameter from the DP-Master.
Check the relevant parameters.
DP-Slave
b15
The station is controlled by another DP-
Master.
Check that multiple DP-Masters are communicating with the same
DP-Slave.
Check the relevant parameters.
DP-Master
Status 2
b0
Parameter send request from DP-Slaves
■
When data exchange starts
The station is in normal operation. (This bit turns on every time
when data exchange starts.)
■
When data are being exchanged.
Check the status of the DP-Slave and PROFIBUS line.
DP-Slave
b1
A malfunction occurred in the DP-Slave.
Check the status of the DP-Slave.
DP-Slave
b2
Not used
b3
A DP-Slave is monitoring their watchdog
timer.
The station is in normal operation.
DP-Slave
b4
Not used
b5
Not used
b6
Not used
b7
A parameter setting excluded the station
from data exchange.
■
When data exchange stops
The station is in normal operation. (This bit turns on every time
when data exchange stops.)
■
When data are being exchanged
Check that a Class 2 DP-Master on the network has not changed
any relevant parameter.
