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 connection and max 3 class-2 master
connections 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 class-2 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)
to the listed DP slave elements:
Index Access Description
A0h R Device name as ASCII code (VIPA 306-1...)
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)
80h R Rack periphery assignment outputs
81h R Rack periphery assignment inputs
F2h R Process image input module
To access the process image of an input module in the rack, for the SFB 52
as
ID
the
start address
is to be used
.
The
start address
may be preset
during hardware configuration of the corresponding module with its
properties at "Address/ID".
With the record set number F2h as
Index
you have reading access to the
process image of the appropriate input module.
The access to the output modules is acknowledged by an error message.
