S7-300 CPU 31x -- Configuring and programming communication -- Configuring PROFINETinterfaces

	How do you display the diagnostics buffer of a SIMATIC CPU with integrated web server on a SIMATIC Panel?
	Which "local_device_id" do you parameterize in order to establish a connection to FB65 "TCON" for open communication via Industrial Ethernet?
	How do you reset the IP address and device name of an I device?
	Why is the message "This page is not available" displayed in the web browser when you call the HTML page "Topology", for example, to read out the topology via the web server of the CPU?
	How do you activate the "Prioritized OCM communication" function to improve the OP communication performance?
	What should you watch out for when parameterizing the watchdog time when a ring redundancy is established with the Media Redundancy Protocol?
	Which CPU can you operate as a PROFINET I device?
	What should you watch out for with a remote access to a SIMATIC S7 with STEP 7 via the Internet?
	In the user program of an S7-300 or S7-400 CPU with integrated PN interface, how can you read out the current topology of the PROFINET IO system connected?
	Where can you find sample S7 programs and documentation for communication via PROFINET on the SIMATIC NET Quick Start Collection?
	Where can you find sample S7 programs and documentation for communication via Industrial Ethernet in the SIMATIC NET Quick Start Collection?
	What differences are there when configuring S7 connections?
	Which settings are required to access the web server of the CPU via a PC with a second network card even though a proxy server is set?
	Can you implement an S7 317-2 PN/DP CPU instead of an S7 315-2 PN/DP CPU configured in iMap?
	How do you read data consistently from a DP standard slave/PROFINET IO device and write it consistently to a DP standard slave/PROFINET IO device?
	What can you do when communication errors occur sporadically with a PROFINET interface of the S7 300 CPU 31x-2 PN/DP?
	From which library should you take the communications FBs?
	What are the commonalities and differences between configured communication connections and the open Ethernet communication?
	What are the differences when assigning the MAC address?

What are the differences when assigning the MAC address?

Configuration Notes:
The MAC addresses of CPU 317 PN/DP and CPU 315-2 PN/DP are preset and cannot be changed in the STEP 7 Hardware Configuration. You can identify the MAC address of the CPU via "PLC > Assign Ethernet address...".
