Hi SHURIK, The message $115 indicates that there is no communication between CPU and OP. Here is a link to a manual: http://support.automation.siemens.com/WW/view/en/1137086 You should remember, that you need special FB in the S5-CPU. Check this and also check cable between OP and CPU. Hope this will help. Best regard, Wizard |
