s7-200 communication module clarification

Hello,
I have a s7-200 with a password protection for uploading. it's both communication ports are used as master for communicating with HMI and Drives.Can i communicate with it If i add a PPI communication expansion module without making any modification in the configuration(as it's protected) ??
if yes, how can i set the slave address or the baud rate of this module ??

thanks in advance

No, you can't. You need to enter the extra communication module in the configuration to be able to use it.

Kind regards,

thanks

Dera jvdcande,
