Title: Ladder Scan speed
Post by: Philippe Parmentier on March 07, 2014, 04:00:36 PM

Hello Everyone,

I'm getting some '2 years old FMD88-10   FirmWare 78A'  where  it's written Rev 1 on the motherboard
and a 'new FMD88-10 Firmware 81' where it's written Rev 3 on the motherboard

When uploading my software and displaying the ladder logics scan counter per  seconds,

I'm on 700 ladder scan per seconds and on the new harware more than 1350 ladder scan per seconds.

Is this difference  due to hardware or firmware? Is there a way to speed up the olds FMD88-10?

Regards.

Philippe

In the newer firmware the CPU runs at faster clock speed than older firmware, which explains the different scan time.

Firmware upgrade on FMD PLC can only be performed at the factory. If you wish to upgrade the firmware please contact the seller and arranged for shipment to the factory for upgrade.
