Using blocks
● System blocks
The required blocks for basic communication are created automatically during the
generation in the CPU.
You do not need to use these blocks manually in the CPU.
The system blocks handle central tasks such as startup, monitoring of the connections,
reachability of the connection partners, entering data in the send mailbox or taking data
from the receive mailbox of the communication DBs, general request, time keeping,
handling communication etc.
Communication DBs:
–
S7-300/400
For each connection a separate communication DB is created automatically: It
contains the send and receive mailbox and all the data required for controlling and
monitoring this connection.
– S7-1500
For the CPU 1500, there is only one communication DB "BConnectData". A
connection instance is stored in this DB in the "BConnection" array for each local
connection.
● Data point typicals
You need to use data point typicals on the relevant CPU according to the
communications tasks.
Drag the individual blocks with the mouse from the global library to the user program of
the CPU. The corresponding instance data block is created automatically when using a
data point typical.
–
Dat256D_S / Dat256D_R
Copy also the UDT "TransmitBlock" for these typicals from the library (Types > PLC
data types (UDT)) into the "PLC data types"directory of the CPU. The UDT is not
automatically referenced by the typical.
● Optional blocks
You should also use the optional blocks on the CPU depending on the communications
tasks of the station.
Drag the individual blocks with the mouse from the global library to the user program of
the CPU.
