Pg Communication - Siemens SIMATIC S7-1500 Function Manual

PG communication

Properties
Using PG communication, the CPU or another module capable of communication exchanges
data with an engineering station (for example PG, PC). The data exchange is possible via
PROFIBUS and PROFINET subnets. The gateway between S7 subnets is also supported.
PG communication provides functions needed to load programs and configuration data, run
tests, and evaluate diagnostic information. These functions are integrated in the operating
system of the module capable of communication.
Requirements
● The PG/PC is physically connected to the communication-capable module.
● If the communication-capable module is to be reached via S7 routing, the hardware
configuration has to be loaded in the participating stations (S7 router and end point).
Procedure for connecting online
You must establish an online connection to the CPU for the programming device
communication:
1. Select the CPU in the project tree in STEP 7.
2. Select the "Online > Go online" menu command.
