I have a customer who would like to log production data on his C-More HMI - easy enough. But he also wants to DISPLAY it (date, Job Number, Production Count) ON the HMI As far as I can see the only way to display logged data is with a trend, which makes no sense in this application. Any suggestions other than do all the logging in the PLC and use a page full of Numeric and string Displays? Thanks Neil

I usually put relative machine data on the HMI... it's just the data that's in a plc register anyway. I use the plc to send the data via email at a set time (shift change, end of workday) and clear the registers for the next day.

They want to be able to see product changes and totals over a weeks production run. I had not planned to archive all the data in the PLC - since that is what logging on most MMI's would do for me.
I do not think this system will be on the plant network - rather stand along, but you did bring up a point - if it is on the network maybe they would be happy to have the log file emailed to them - after all they probably will just display it and write it down anyway.

Have you thought of uploading the data via FTP to their server, then they can pull up the file and work it anyway they want. But I would think that they have an HMI monitoring the system and it should be logging the system. If not sell them Automation Directs Point of View for logging software. I have been using the original vendors software for years and for data logging it cannot be beat. Also ADC has other data logging options that are OPC based.
