DP-V1 Services

Overview
Data from
DP-V1 slave
Structure stored
diagnostic entry
3-14
For the deployment of the DP-V1 services you have to take care that your
CPU supports DP-V1 communication. More detailed information about this
is to be found in the description of your CPU. The following system function
blocks are available for this:
SFB 52 Read record set from a DP slave
SFB 53 Write record set to a DP slave
SFB 54 Receive interrupt from a DP slave
Per default, one class-1 master and max 3 class-2 master connection with
244Byte data (4Byte DP-V1 header plus 240Byte user data) are supported.
The class-1 master connection is established together with the cyclic
connection and is activated via the parameterization. The class-2 master
connection can be used by a C2 master that then communicates with the
slave only acyclical and provides an own connection establishment.
To access the DP-V1 slave with the Siemens SIMATIC Manager the
diagnostic address, which can be set by properties, is used as ID.
Using the following record set no. as Index you get access for reading (R)
res. writing (W) to the listed DP slave elements:
Index Access Description
A0h R Device name as ASCII code (VIPA 353-1DP01)
A1h R Hardware Version as ASCII code (V1.00)
A2h R Software Version as ASCII code (V1.00)
A3h R Serial number of the device as ASCII code
(e.g. 000347 = 30h, 30h, 30h, 33h, 34h, 37h)
A4h R Device configuration (see table next page with module
identification assigned to module type)
R Number of stored diagnostic
D0h
W Any write instruction deletes every diagnostic entries
R Read diagnostic entries in sequence
D1h
W Any write instruction stores diagnostic entries
permanently in the FLASH memory
With every D1h call a stored diagnostic entry with max. 26Byte is displayed
starting with the newest one.
Basically every stored diagnostic entry has the following structure:
Label Type
Length Word
Time stamp Double word Internal time stamp
Diagnostic Byte
(max. 20Byte)
