Hello, I am working on a Siemens S7-300 PLC with a WinCC HMI and I am looking to perform logging of certain values every 12 or 24 hours. Basically I have a Flow meter that constantly has flow through it. Right now I have the PLC set up to record the current value of the flow, as well as a totalizer to indicate how much flow has gone through the valve. (until an operator chooses to reset it) I need to create some sort of logic or utilize something in WinCC to calculate the flow through the valve only for that day. After that day, the value will be either deleted or replaced with a new value the next day... If anyone has any tips or advice it would be greatly appreciated. Thank you,

Hi I am having a problem with an error/fault code. The fault comes from a lenze drive as an integer. We have a proface HMI monitoring a DBW in the siemens S7 300 that holds the lenze fault code. The PLC comes up with a generic code "lenze drive fault". The proface comes up with the drive code. I would like the PLC to produce a fault description using the lenze fault code in the DBW, instead of the generic one [listed above]. could anyone please help with this problem Thanks Robbo
