1.1 Configuration
1.1.1 Configuring Safety-Related Master to I-Slave Communication
Overview
Note
This section is only relevant if you are using S7 Distributed Safety V 5.2 + SP 1
with STEP 7, ≤ V 5.2.
If you use STEP 7, ≥ V 5.2 + SP 1, the information in Sections 1.1.2 through 1.1.4
is relevant to you.
The manual describes safety-related master to master communication.
The following section describes the configuration of an additional safety-related
communication option, that is, safety-related communication between safety
programs in different F-CPUs. As in a standard system, safety-related
communication between the safety program of the F-CPU of a DP master and the
safety program(s) of the F-CPU(s) of one or more intelligent DP slaves takes place
by means of master to I-slave connections.
You do not need any additional hardware for the master to I-slave communication.
Communication by Means of F_SENDDP and F_RCVDP
Safety-related communication occurs by means of the F-application blocks
F_SENDDP and F_RCVDP that you used in the safety programs of the F-CPUs.
