● If you have the "Obtain an IP address automatically" selected you may want to change
the selection to "Use the following IP address" to connect to the S7-200 SMART CPU:
– Select an IP address on the same subnet as the CPU (
192.168.2
.1).
– Set the IP address to an address with the same Network ID (for example,
192.168.2
.200).
– Select a subnet mask of
255.255.255
.0.
– Leave the default gateway blank.
– This will allow you to connect to the CPU.
Note
The Network Interface Card and the CPU must be on the same subnet to allow
STEP
7-MicroWIN SMART to find and communicate to the CPU.
Consult your IT personnel to help you set up a network configuration to allow you to connect
to the S7-200 SMART CPU.
