Hi.

How to select memory card for MP 277, touch. There are 3 types of memory card available for this HMI. 256MB, 512MB and 8GB(USB which is expensive).

My question is

1. How to calculate memory card size?

2. What will happen, after a certain time of use when the available space is 0.

Thanks.

Hello SAR2013,

Perhaps you can tell us, why you want to use a memory card?

Best regards,

Hi.

Memory card will use to store historical data.

Hello SAR2013,

It depends on how you have configured Historical Data.

And will you archive the Log file to a PC?

In the parameterizing of Historical Data, you can see how big the Log files will be.

When LOG file is full, it will go overwrite the oldest data.

Best regards,
