Posted 14 Jan 2017 Hi everybody, We still run some old PLC5 plc in our system. The pograms get changed on a regular basis and always given a new name. For example PLC_FORE_12, new version would be PLC_FORE_13. It seems that somehow in the latest running version the IO configuration has disappeared. When I open an earlier version it's still there. My question is if it's possible to retrieve the information in the latest program somehow ? Share this post Link to post Share on other sites
Posted 14 Jan 2017 The discrete I/O is easy enough to add back in tot the I/O config. The analog will require you to add the BTW/BTR files by hand though the module configuration should already be set. I know of no other way to otherwise repopulate the chassis with the I/O configuration. However, you could always attempt upload the current processor file into the older project file and unless there has been some I/O module changes (types/positions). you might be able to update the project file with the current setup. You may still have to tweak the I/O configuration a bit. Make sure you have a second copy of that older project file before you try this. 1 person likes this Share this post Link to post Share on other sites
