Selecting the Correct Interface Parameter Set and Setting It Up

When you have reached the Set the PG/PC Interface dialog box, be sure that
"Micro/WIN" appears in the Access Point of Application list box (see Figure 7-4).
The Set the PG/PC Interface box is common to several different applications, such
as STEP 7 and WinCC, so you may need to tell the program the application for
which you are setting parameters.
When you have selected "Micro/WIN" and have installed your hardware, you need
to set the actual properties for communicating with your hardware. The first step is
to determine the protocol that you want to use on your network. You should use
PPI protocol for all of your CPUs.
When you have decided what protocol you want to use, you can choose the
correct setup from the Interface Parameter Assignment Used list box in the Set the
PG/PC Interface dialog box. This box lists each hardware type that you have
installed, along with the protocol type in parentheses. For example, a simple setup
might require you to use the PC/PPI cable to communicate with a CPU 222. In this
case, you select "PC/PPI cable(PPI)."
After you have selected the correct interface parameter set, you must set up the
individual parameters for the current configuration. Click the "Properties..." button
in the Set the PG/PC Interface dialog box. This action takes you to one of several
possible dialog boxes, depending on the parameter set that you selected (see
Figure 7-7). The sections that follow describe each of these dialog boxes in detail.
In summary, to select an interface parameter set, follow these steps:
1. In the Set the PG/PC Interface dialog box (see Figure 7-4), select "Micro/WIN"
in the Access Point of Application list box in the Access Path tab.
2. Ensure that your hardware is installed. See Section 7.2.
3. Determine the protocol that you want to use. You should use PPI protocol for
all of your CPUs.
4. Select the correct setup from the Interface Parameter Assignment Used list
box in the Set the PG/PC Interface dialog box.
5. Click the "Properties..." button in the Set the PG/PC Interface dialog box.
From this point, you make selections according to the parameter set that you
chose.
