Frequently Asked Questions
Can I use 6ES7953-8LG20-0AA0 for a PN/PN coupler firmware update?
The coupler firmware-update procedure requires at least 2 MB, so a 128 KB card is too small.
What happens when I insert an empty 6ES7953-8LG20-0AA0 into a coupler that already has a device name?
The empty card adopts the existing device name.
Can 6ES7953-8LG20-0AA0 hold both coupler device-name data and firmware-update data for the same procedure?
The coupler uses one card for either device-name data or firmware-update data.
From which PN/PN coupler product version is 6ES7953-8LG20-0AA0 listed?
The additional memory-card list applies from product version 2 of the PN/PN coupler.
How should I plan repeated writes to 6ES7953-8LG20-0AA0 in a PN/PN coupler?
Keep the number of write/delete sequences within the specified 100,000-cycle service-life limit.
Which conditions accompany the ten-year service-life figure for 6ES7953-8LG20-0AA0?
The figure applies at ambient temperatures up to 60 °C and within the stated write/delete-cycle limit.
What should I compare before choosing 6ES7953-8LG20-0AA0 for a SIMATIC project?
Match the supported 3.3 V Nflash memory interface and ensure that the storage requirement fits within 128 kbyte.
