Follow these steps to set up the PPI parameters:
1. In the PPI tab, in the Station Parameters area, select a number in the Address
box. This number indicates where you want STEP 7-Micro/WIN 32 to reside on
the programmable controller network. The default station address for the
personal computer on which you are running STEP 7-Micro/WIN 32 is station
address 0. The default station address for the first PLC on your network is
station address 2. Each device (PC, PLC, etc.) on your network must have a
unique station address; do not assign the same address to multiple devices.
2. Select a value in the Timeout box. This value represents the length of time that
you want the communications drivers to spend to attempt to establish
connections. The default value should be sufficient.
3. Determine whether you want STEP 7-Micro/WIN 32 to participate on a network
that has multiple masters. You can leave the check mark in the Multiple Master
Network box, unless you are using a modem or Windows NT 4.0. In that case,
the box cannot be checked because STEP 7-Micro/WIN 32 does not support
that functionality.
4. Set the transmission rate at which you want STEP 7-Micro/WIN 32 to
communicate over the network. The PPI cable supports 9.6 kbaud and
19.2 kbaud.
5. Select the highest station address. This is the address where
STEP 7-Micro/WIN 32 stops looking for other masters on the network.
