Siemens has recently announced that the LOGO! 6 basic devices and expansion modules will only now be available as a spares part only. While the LOGO! 6 will still be available until product cancellation, Siemens shall be ensuring the continued availability of spare parts by limiting the number of spare products supplied to a maximum of three units per order, orders above this will not be supplied.
There are replacements for the LOGO! 6 that we will look at in the following article.
What is The Replacement For Siemens LOGO! 6?
The Siemens LOGO! 6 has been replaced by the Siemens LOGO! 8 range of logic modules. The new controllers offer significant benefits over the LOGO! 6 range. For reference we have listed below the replacement versions of the basic devices:
|Product Designation||LOGO! 6||LOGO! 8|
|LOGO! 230 RCE||6ED1052-1FB00-0BA6||6ED1052-1FB08-0BA0|
|LOGO! 230 RCEo||6ED1052-2FB00-0BA6||6ED1052-2FB08-0BA0|
|LOGO! 24 RCE||6ED1052-1HB00-0BA6||6ED1052-1HB08-0BA0|
|LOGO! 24 RCEo||6ED1052-2HB00-0BA6||6ED1052-2HB08-0BA0|
|LOGO! 24 CE||6ED1052-1CC01-0BA6||6ED1052-1CC08-0BA0|
|LOGO! 24 CEo||6ED1052-2CC01-0BA6||6ED1052-2CC08-0BA0|
What Are The Benefits of The LOGO! 8?
The Siemens LOGO! 8 offers significant benefits for users of LOGO! 6 devices in including the price and availability benefits now that the LOGO! 6 is a spares part.
Siemens LOGO! 8 has eight basic modules that now have an Ethernet connection allowing program transfer and communication on standard Ethernet networks. Siemens LOGO! 8 can be incorporated into large automation networks for communication to SIMATIC S7-compatible devices, and Modbus TCP/IP integrated.
The eight basic modules have improved hardware to the LOGO! 6 and have an extended temperature range without condensation with a range of -20 to 55 °C. The LOGO! 8 display now has double the space available compared to the LOGO! 6 device and has three background colours to choose from, ideal for displaying warnings and signalling.
In addition to the embedded Ethernet communication the new LOGO! 8 has an integrated web server for cost-effective remote user control and monitoring of the program. The design of the web server interface allows users to create web pages even if you have no HTML experience.
The Siemens LOGO! 8 can also be used as a cost-effective data logger allowing monitoring of processes combined with the LOGO! Access tool users can now export the data to a CSV file.
What is The Difference Between LOGO! 6 And LOGO! 8
|Features of the LOGO! 8||Benefits||Comparison to LOGO! 6|
|Eight basic modules with Ethernet connectivity||Communication on Ethernet networks. No special programming cable required. Easier programming via Ethernet.||Eight modules with no integrated communication|
|400 function blocks||Enhanced program memory||200 function blocks|
|GSM/GPS Communication Module||Communication via text message and time synchronisation.||Remote control and alarming possible by external devices, no time synchronisation|
|Integrated Web Server||Remote user control and monitoring||Functionality not available on LOGO! 6|
|Innovative macro function||Allows creation of macro function blocks and libraries, making repeating programme creation tasks more user-friendly.||Functionality not available on LOGO! 6|
|Enhanced display with six lines of text with 16 characters per line. Three background colours||Messages are displayed more clearly. Warnings and signalling can be communicated allowing diagnostic via the display.||Four lines with 12 characters per line. Only one backlight that is switchable.|
|Data Logging||Process values can be stored in the internal memory or micro SD card||Functionality not available on LOGO! 6|
|Data Transfer to PC in run mode via LOGO! Access Tool||Process data can be exported in a CSV file and analysed in Excel||Functionality not available on LOGO! 6|
|Touch Panel HMI can be connected||The latest operator HMI panels can be connected allowing additional features such as graphical options||Functionality not available on LOGO! 6|
|Extended temperature range -20 to 55 °C||Outdoor use||0 to 55 °C|
|Modbus TCP/IP||Communication to other third-party devices||Functionality not available on LOGO! 6|
|Time synchronisation via NTP client and server||Ensures all LOGO! modules in a system have the same time||Functionality not available on LOGO! 6|
Frequently Asked Questions About Siemens LOGO! 6 Conversion to LOGO! 8 Devices
