DP-V1 Services
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
