Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury
will
result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury
may
result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Manual, 12/2014, A5E33619758-AB 15
Calling instructions for distributed I/O
Multiple calls are required for the instructions of the distributed I/O.
The duration of the call processing is dependent on the load, bus cycle time and
transmission rate. Timeouts may occur if these instructions are called in a loop within a
cycle.
Exceptions:
●Only one call is necessary for the RALRM instruction "Receive interrupt".
Program blocks for DPV1 (according to PNO standard) 1):
●"Read data record from a DP slave" RDREC instruction is functionally equivalent to
SFC59 (write record)
●"Write data record to a DP slave" WRREC instruction is functionally equivalent to SFC58
(read record)
●"Read interrupt information from a DP slave" RALRM instruction call is made within an
interrupt OB

Status and error displays
Introduction
Diagnostics by means of LEDs is an initial tool for error localization. In order to localize
errors still further, you usually evaluate the display of the module status in STEP 7 or the
diagnostics buffer of the CPU. The buffer contains plain text information on the error that has
occurred. For example, you will find the number of the relevant error OB in the plain text
information.
LED display

DP slave diagnostics
DP V1 slave: Diagnostic interrupt
Transmission of diagnostic data is made as a diagnostic interrupt. Diagnostic interrupts must
be acknowledged by the DP master.
Supported diagnostic functions
The CM DP supports the following blocks of the DP diagnostics:
●Standard diagnostics (6 bytes)
●Identifier-related diagnostics (2...17 bytes depending on the number of configured transfer
areas)
●Module status (5...35 bytes depending on the number of configured transfer areas)
●Diagnostic interrupt (8 bytes, if any)
User program (DP master)
The "DPNRM_DG" instruction is used to read the diagnostic data of a DP slave (DP single
diagnostics) in the DP master.
The diagnostic interrupts for DP V1 slaves are periodically evaluated in the user program of
the master via the "RALRM" instruction.
You can find the required parameter assignment for the instruction in the STEP 7 online
help.
The following is a structural overview of the diagnostic data.

Bit no.
Name
Explanation
7 Master_Lock The DP slave was configured by a different DP master. The DP slave can only be
accessed read-only by the DP master configured as productive.
This bit is set by the DP master when its bus address does not match the
configured address.
6 Parameter_Fault The most recently received parameter frame was corrupt or not permitted. This bit
is set by the DP slave.
Remedy: Check the parameter assignment with respect to invalid parameters.
5 Invalid_Slave_Response This bit is set by the DP master if an implausible response has been received by
the DP slave.
4 Service_Not_Supported This bit is set by the DP master if a function is called by the master that is not
supported by the DP slave.
Remedy: Disable the parameter assignment of the required function at the master.
3 Ext_Diag This bit is set by the slave.
•Bit =1: Diagnostic data is available in the diagnostic area specific to the slave.
The diagnostic data can be evaluated in the user program of the master.
•Bit =0: A status message can be available in the diagnostic area specific to the
slave. The status message can be evaluated in the user program of the master.
2 Slave_Config_Check_Fault The configuration data sent by the DP master is rejected by the DP slave.
Cause: Configuration error. Remedy: Change the configuration.
1 Station_Not_Ready The DP slave is not yet ready for productive data exchange.
This is a temporary condition and cannot be influenced by the DP master.
0 Station_Non_Existent The DP slave is not responding on the bus.
This bit is set by the DP master 1 (the slave permanently sets this bit to 0). If the bit
is set, the diagnostic bits contain the status of the last diagnostic alarm or the initial
value.
