Meaning / Effect

 

 

S Set IP address in the user

With this option, you specify that the IP address is set over a user

program

program interface (function block IP_CONFIG). This allows the IP

 

address to be supplied dynamically during operation.

 

In this situation, communication connections are created only over

 

the user program interface; configuring connections using STEP 7 is

 

not possible (relates to connections over IP: TCP, ISO-on-TCP, UDP).

 

This setting does not preclude the IP address being obtained from a

 

DHCP server. It is possible for the user program to instruct the

 

module to obtain an IP address in this way.

 

Further information:

 

Read the section “Programmed Communication Connections” and

 

refer to the example in the appendix of the manual.

Note

You can query the IP address actually being used with NCM S7 Diagnostics.
