Support Questions / Compact Logix - Tags with custom type

« on: December 15, 2015, 10:40:58 AM »

Hi

I have a CompactLogix with a Custom type wich I call CustomTimer containing Delay, and Count, both integer
I also have a CustomTimers array of 10 elements of type CustomTimer

I can read and write using CustomTimers[1].Delay, but when I try to simply read CustomTimers as an array, I got Driver Exception saying "No Response from PLC"

Is there an easy way to read/write such arrays, or I really need to scan all values one by one?

Thanks

Support Questions / OverflowException in 3.98f - AllenBradleySLCMicro

« on: April 22, 2015, 12:03:47 PM »

When I try to write to a big array[200], I have an OverflowException in WriteRawData

Code: [Select]

TNS = ProtectedTypeLogicalWrite(Convert.ToByte(DataW.Length), Convert.ToByte(PAddress.FileNumber), _
                                              Convert.ToByte(PAddress.FileType), Convert.ToByte(PAddress.Element), Convert.ToByte(PAddress.SubElement), _
                                             DataW)

in my case, PAddress.SubElement = 328

Support Questions / EthernetIPforCLXCom Big array issue, and Send Que Full issue (V3.68)

« on: September 26, 2014, 11:31:04 AM »

Hi, I have 3 problems,

I have a system that read continuously (every 100ms) some flags from a PLC (3 DInt and a small DInt array of 5 values)
When flags are ready, I send data to the PLC

First problem, When I try to send an array of 100 or 600 values it fails, so I need to send my array in small chunk (I write small array of 20, starting at index 0, 20, 40, ...)

Second problem, when I send small chunk, it works the first time, but it fails with "Send Que Full" on the second one even if I wait 2 minutes or 10 minutes
To solve this, I added a Thread.Sleep(50) before each Write.

Third, when I close, I call Dispose(), and sometimes, I receive a "Send Que Full" error on Dispose, do I need to wait before calling Dispose()


Additional info:
I created a Threadsafe Read/Write architecture to prevent multiple call at once (had issue with that), but not where every write have a Sleep(50) which is not really usefull for performance.
I also call CloseConnection() before calling Dispose()
