SIEMENS CPU 6ES7414-4HJ04-0AB0 is part of the S7-400 range, the most powerful PLC system under the Simatic name. This PLC is most likely to be found in industries where short machine cycle time and high processing speeds are most necessary, such as manufacturing and process automation. Siemens released the Simatic S7 family in 1995, almost 40 years after their first Simatic controller, and today it is still one of the most popular PLC solutions around. With the S7, users can program their PLC with Siemens STEP 7 software, which will be a breeze particularly for people with experience of the previous STEP 5 program. Users of the S7-400 will know that it is ‘hot swappable’ which means that you can add or remove modules whilst the controller is live, making it so much easier to add or remove modules. If you can’t find the module you’re looking for or it’s not in stock online get in touch by phone or email as there could be a successor product suitable for your existing setup.
