DP-V1 services
For the deployment of the DP-V1 services you have to take care that your
master system supports DP-V1 communication. More detailed information
about this may be found in the description of your master system. There
are the following handling blocks available for CPUs, programmable with
Siemens STEP7:
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 a cyclical 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

Via the index 58h, the module configuration of the DP slave may be
monitored. With the 1. word you will get the number of modules. With the
next words you will find the
module type
in the installed sequence.
The
module type
corresponds to the first 4 digits of the
module ID
. The
module ID
may be found in the technical data of the periphery module.
