Each PMCR is having 50bytes of data transfer (Receive+send using Function code 17). I have kept all times in protocol macro as minimum as possible 0.1ms each and maintaining 38.4K baudrate.
Whether this baudrate would be OK to transfer without any problem and how will come to correct times to set in macro?

Another question is now with a counter I am polling 13. To send a data to any perticular selected slave is taking 2sec time. I am thinking to reduce this time. How could i improve? My aim is to make 0.5sec and whether is possible?

somebody could help me?]]> Wed, 18 Nov 2009 04:10:37 -0500 http://forums.mrplc.com/index.php?showtopic=18644 http://forums.mrplc.com/index.php?showtopic=18606 How can I calculate the RPM? Is PRV2 function available for sensors or only for encoders use?
Can me help someone?

My PLC is OMRON CP1L-M30DR

Thank You in advance

I was hoping there is a register that gives that status similar to what AB does.

I have DeviceNet network with CJ2H as a Devicenet master. Barcode scanners are connected to DRT1-232C2.
I use FB to read scanned code. Time between flag - scanner buffer is full and flag that scanned code is in PLC takes aprox. 120ms.
It is quite fast internal transport and sometimes PLC doesn't have enough time to make cylinder movements - the scan time is 9,85ms

Electrical gabinet is not far - I am thinking to use CJ1W-SCU21 card to read the scanner code.

The question is - how much time I can save using CJ1W-SCU21

Thanks
