Hello SIOS Forum Community, We keep getting questions about the back-up batteries of the SIMATIC controllers. Information about the SIMATIC controllers S7-1200 and S7-1500 For the S7-1200 and S7-1500 there is no back-up battery based working memory back-up concept. For the S7-1500 controllers, the SIMATIC S7-1500 power supply module PS 60W 24/48/60VDC HF (order number:6ES7505-0RB00-0AB0) can be used to increase the power on the backplane bus. In addition, this module buffers the energy in the event of mains failures and thus enables the remanence of a CPU's data - without a battery and thus maintenance-free. This shortens the restart of machines and systems, as there is no loss of data. More details can be found in the delivery release and in the following FAQs: https://support.industry.siemens.com/cs/ww/en/view/109746447 https://support.industry.siemens.com/cs/ww/en/view/109746177 Of course, a 24V DC SITOP UPS can be used as an alternative. Information about the SIMATIC Controller S5/S7-300/S7-400 SIMATIC S5 Information on the back-up battery can be found in the manual Which backup battery can be used in a SIMATIC S5? Back-up time, service life and testing of the lithium back-up battery. S7-300 The 1st generation of S7-300 CPUs still worked with a memory card. Here it was necessary to provide a back-up battery for the CPU in order to retain the programme even in the event of a power failure. Information on the back-up battery is given in the device manual for the S7-300 automation system. S7-400 Information on the back-up battery is given in the manual SIMATIC S7-400 automation system S7-400 module data. Where can you find information about the S7-200/S7-300/S7-400 back-up batteries? When do I have to replace the back-up battery on my S7 300/400 controller. Why is a battery error reported when inserting a back-up battery even though the battery is new? Best regards, SIMATIC International Technical Support Hub |
