I have a mitsubishi PLC and we a using the MELLDDE driver for it. This allows excel to retreive data from the plc just like any DDE application (i think). We have a test that our plc controls and we use excel to monitor the test process. Is there a way to have excel log data every minute and move the prevous data to down to the next row and fill the top row with the most recient data and so on? this way i would end up with a log of what happened every minute. This would be my poor mans version of a scada system!
