1.3 PG/OP Communication via Industrial Ethernet
Application
PG/OP communication provides functions that are already integrated in every
SIMATIC S7/M7/C7 device.
A distinction must be made between the following two types of function:
S PG communication
PG communication with STEP 7 PLCs on Industrial Ethernet means the
following:
– You can use the complete range of functions of STEP 7 on Industrial
Ethernet.
– You can use programming, diagnostic, operating and monitoring functions on
all modules in the SIMATIC S7 PLC via Industrial Ethernet.
S OP Operation
PG/OP communication on Industrial Ethernet allows the operation and
monitoring of all modules in a SIMATIC S7 PLC using operator interface
systems (TD/OP).
The Ethernet CP acts as a “communications relay” that relays the PG/OP
communication via Industrial Ethernet.
