be configured in STEP 7 V5.
● GPRS station
● MSC station
● Neutral
S7 communication and PG/OP communication
Reading / writing data from / to a CPU via the mobile wireless network is possible if S7
communication is enabled in the configuration of the CP.
The following instructions are supported:
● PUT/GET
The CP supports these program blocks as client and server for data exchange with
remote stations (S7-300/400/1200/1500)
● PG functions
● Operator control and monitoring functions (HMI)
You will find details on the program blocks in the information system of STEP 7 Basic.
For S7 communication, the CP requires a fixed IP address.
Communication via Open User Communication (OUC)
Via the Ethernet interface of the CP and the program blocks of the Open User
Communication on the CPU the CP has the following communication options:
● Communication with SIMATIC stations via S7 connections
● Sending e-mails
In contrast to the corresponding service of telecontrol communication (see above), to
transfer e-mails via OUC, program blocks TMAIL_C need to be used, see section
