Note
The length of the diagnostic frame varies:
• For IM151-1 BASIC, between 6 and 43 bytes.
• For IM151-1 COMPACT, between 6 and 44 bytes.
• For the IM151-1 STANDARD, IM151-1 FO STANDARD and IM 151-1 HIGH FEATURE

Station statuses 1 to 3

Definition
Station statuses 1 to 3 provide an overview of the status of a DP slave.
Structure of station status 1 (byte 0)
Table 8-5 Structure of station status 1 (byte 0)
Bit
0 1: The DP slave cannot be accessed by the DP
master.
1 1: The DP slave is not yet ready to exchange data.
2 1: The configuration data transferred from the DP
master to the DP slave do not match the slave
configuration.
3 1: External diagnostic information exists. (Group
diagnostic display)
4 1: The required function is not supported by the DP
slave (for example, changing the PROFIBUS
address by means of software).
8-24
(depending on the parameterization)
– Between 6 and 62 bytes in DPV0 mode
– Between 6 and 110 bytes in DPV1 mode (STANDARD)
– Between 6 and 128 bytes in DPV1 mode (HIGH FEATURE)
Meaning Cause/remedy
Is the correct PROFIBUS address set on the DP slave?
•
Is the bus connector plugged in?
•
Voltages on DP slave?
•
RS 485 repeater set correctly?
•
DP slave reset?
•
Wait, the DP slave is currently starting up.
•
Correct station type or correct configuration of the DP
•
slave entered in the configuration software?
Evaluate the channel-related diagnostic information, the
•
module status and/or the channel-related diagnostic
information. As soon as all errors have been eliminated,
bit 3 will be reset. The bit will be set again when there is a
new diagnostic message in the bytes of the
aforementioned diagnostics.
Check the configuration.
