PROFIBUS DP DIP switches (CU240S DP and CU240S DP-F)
The PROFIBUS DP address can be set via seven DIPswitches or via parameter "P0918". If
an address is set via DIP switches, the value of p0918 will be ignored. The PROFIBUS DP
address can be set between 1 and 125.
In the factory setting the PROFIBUS DP address DIP switches are in the OFF position.
