Overview
On April 5th of this year, the European Union released a legislative draft for the 954-8LF02-0AA0 Siemens module, proposing to revise the 2014 Fluorinated Greenhouse Gas Law and strictly control greenhouse gas emissions in the future. Currently, fluorinated gases account for 2.5% of the total greenhouse gas emissions in the European Union. The draft $r $n will reduce greenhouse gas emissions containing fluorine, enabling the EU to reduce approximately 40 million tons of carbon dioxide (CO2) emissions equivalent by 2030 and an additional 100 million tons of CO2 emissions equivalent by 2050. $r $n $r $n $r $n Sulfur hexafluoride (SF6), as a fluorinated greenhouse gas, is used in transmission and distribution

On April 5th of this year, the European Union released a draft legislation to revise the 2014 Fluorinated Greenhouse Gas Law, which will strictly control greenhouse gas emissions in the future. Currently, fluorinated gases account for 2.5% of the total greenhouse gas emissions in the European Union. draft
By reducing greenhouse gas emissions containing fluorine, the EU will reduce approximately 40 million tons of carbon dioxide (CO2) emissions equivalent by 2030 and an additional 100 million tons of CO2 emissions equivalent by 2050.
Sulfur hexafluoride (SF6), as a fluorinated greenhouse gas, has been used as an insulating gas in power transmission and distribution equipment for over 35 years, and is widely used in medium voltage gas insulated switchgear. However, SF6 has been criticized as a greenhouse gas and has the potential to contribute to global warming
The Global Warming Potential (GWP) is 23500, which means that 1 ton of SF6 is equivalent to 23500 tons of CO2, with carbon emissions that can persist in the atmosphere for up to 3200 years. With the advancement of technology and the development of the industry, products that replace SF6 with other chemical gases have gradually appeared in the market. Although they
The dielectric strength is equivalent to SF6 and has good environmental characteristics, but its stability is not strong and it is prone to liquefaction at room temperature. Therefore, it needs to be mixed with other gases, which will greatly increase maintenance costs.
MPI can be used to establish a simple network of 32 nodes with a data transmission rate of 187.5 Kbit/s. The CPU can establish up to 64 connections with nodes on the communication bus (C-bus) and MPI.
Note:
When using both PROFIBUS DP and MPI interfaces, only the following bus connectors can be connected to the MPI interface:
With socket: 6ES7 972-0BB42-0XA0
Without socket: 6ES7 972-0BA42-0XA0
PROFIBUS DP interface:
Through the PROFIBUS DP interface, redundant and distributed automation configuration can be achieved, thereby improving speed and facilitating use. For users, distributed I/O is handled as centralized I/O (with the same configuration, addressing, and programming).
PROFINET interface with 2 ports (switch):
Support system redundancy and MRP (Media Redundancy Protocol)
