Posted 5 Jan 2010 I have a battery low light on our S5 PLC's. I purchased new batteries and wanted to know if there is a specific procedure to installing them. I have power on the processors and the machine is running. Is this just a simple switch out? Thanks Share this post Link to post Share on other sites
Posted 5 Jan 2010 You should be able to change the battery while your powered up. Share this post Link to post Share on other sites
