There is a technique for special exchanges between a PLC and a Windows-based panel such as the MP 270 called "user data areas", they allow error messages, date-and-time info, active page number changes, and others. One of these areas is named Coordination and contains a Life Bit. See the manual: Communications for Windows-based systems, part 1 http://support.automation.siemens.com/WW/view/en/1145110 Once you have studied chapter 7 of the manual, and created the Coordination area in the PLC as described, you can use the state of the Life Bit to trigger your Loss of communication page. Hope this helps, Daniel Chartier Attachment ProTool_LifeBit.JPG (129 Downloads)

Then just to send this DT variable to the panel. Best regards, Hristo Mihalev

However, you must first find out if these exist in your PLC. Check the CPU properties of your CPU (in the HWConfig editor) under Blocks and see if OB32 s geryed-out unavailable). Generally OB35 is available by default in all S7 300-CPUs. Try transfering your code to OB35 and tell us if it still in error. By the way, what information does the compiler give you when it changes the code to red? Place your cursor on the incorrect code and you should read the system message that applies. Hope this helps, Daniel Chartier

How can you read out the date and time with SFC1 (READ_CLK) and input them with SFC0 (SET_CLK)? just put there in ENO input of this block your DB1.DBX1237.1 in positive edge. Memorize then output of data and time in DB1... Best regards, Hristo Mihalev
