SIMATIC S7-200 RS-232/PPI Multi-Master Cable and S7-200 USB/PPI Multi-Master

Cable

Thank you for purchasing the SIMATIC S7-200 Multi-Master PPI Cable.

The S7-200 RS-232/PPI Multi-Master Cable comes factory set for optimal performance with the STEP 7--Micro/WIN 3.2 Service Pack 4

(or later) programming package. The factory setting for this cable is different than for the PC/PPI cables. Refer to Figure 1 to configure the cable for your application.

You can configure the S7-200 RS-232/PPI Multi-Master Cable to operate the same as the PC/PPI cable and to be compatible with any version of a STEP 7--Micro/WIN programming package by setting Switch 5 to the PPI/Freeport setting and then selecting your required baud rate.

The USB cable requires STEP 7--Micro/WIN 3.2 Service Pack 4 (or later) programming package for operation.

Use the S7-200 RS-232/PPI Multi-Master Cable with STEP 7--Micro/WIN as a replacement for the

PC/PPI cable or for Freeport operation

For connection directly to your personal computer:

!

!

!

!

Set the PPI/Freeport mode (Switch 5=0)

Set the baud rate (Switches 1, 2, and 3)

Set Local (Switch 6=0). The Local setting is the same as setting the PC/PPI cable to DCE.

Set the 11 Bit (Switch 7=0)

For connection to a modem:

!

!

!

!

Set the PPI/Freeport mode (Switch 5=0)

Set the baud rate (Switches 1, 2, and 3)

Set Remote (Switch 6=1). The Remote setting is the same as setting the PC/PPI cable to DTE.

Set the 10 Bit or 11 Bit (Switch 7) to match the number of bits per character setting of your modem.

Use S7-200 RS-232/PPI Multi-Master Cable with STEP 7--Micro/WIN 3.2 Service Pack 4 (or later)

For connection directly to your personal computer:

!

!

Set the PPI mode (Switch 5=1)

Set Local (Switch 6=0)

For connection to a modem:

!

!

Set the PPI mode (Switch 5=1)

Set Remote (Switch 6=1)
