CP 1626 in a PC as IO device
The following figure shows a typical application:
Two PCs each with a CP 1626 as PROFINET IO device at the IO device level.
There are also a PC with a CP 1626 as PROFINET IO controller, a SIMATIC S7-400 with a
CP 443-1 as PROFINET IO controller and two SIMATIC S7 ET 200S PROFINET IO devices
connected in the network.
On the IO device PCs, there is an IO-Base device user program running that accesses the
functions of the IO-Base user programming interface. The data traffic is handled via a CP
1626 to a PC as PROFINET IO controller or an S7-400 automation system with a CP 443-1
via Industrial Ethernet.
