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 CP supports the following functions:
●
PUT/GET
The CP supports the function as client (program blocks) and server for data exchange
with remote stations (S7-300/400/1200/1500).
●
S7 routing
Communication between stations via S7 connections
●
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, the TMAIL_C program block needs to be used, see section
Program blocks (Page 167).
1.4
Connection to SINEMA RC
Communication via SINEMA Remote Connect (SINEMA RC)
The "SINEMA RC Server" application provides end-to-end connection management of
distributed networks via the Internet. This also includes secure remote access to lower-level
stations. Communication between SINEMA RC Server and the remote devices takes place
via a VPN tunnel with consideration of the stored access rights.
SINEMA RC uses OpenVPN for encryption of the data. The center of the communication is
SINEMA RC Server via which communication runs between the subscribers and that
manages the configuration of the communications system.
SCALANCE M routers, which you can use for the connection, also support OpenVPN and
connection to SINEMA Remote Connect.
For the CP firmware version required for communication via SINEMA RC see section
Communications services (Page 14).
The CP can also handle telecontrol communication via the SINEMA RC server.
