SET SYSID
The parameters shown are CP-L2 default parameters in the programmer, and must be matched to
the basic L2 parameters of the system ( Table 1-4, 1-5)!
Position the cursor to the parameter you want to change. You can select the baud rate and the
physical bus characteristics with <F3>.
Press <F1> (SET SYSID) to confirm and save the parameters you have changed.
9.6 Activating an Edited Path
You must always match the basic L2 parameters of the CP-L2 to the basic L2 parameters of the
system before activating a path starting at a programmer with an integral CP-L2 communications
processor ( section 9.5).
You can activate an edited path
• in the BUS DIALLING utility ( FUNCTION SELECTION screen)
or
• in an S5 program package with a path selection facility.
Activating a path establishes a communications link to a remote station.
