Thanks for you reply, admin. But i also test with only 2 scripts (seq_PollingDPM and seq_PollingOTB); run main script at start up, call 2 scripts to get data, and DAQ is crash too. I guest Registry is reason before, but it is not really reason to make DAQ crash. I test main script with one of other script, it 's work. The error is only appear when i run seq_PollingDPM script. Is it too many try/catch in this? or get many channels of many devices? I will reduce my Registry variables. Thanks so much.

Data is ok. i may be a graphic problem? winserver 2012 user intel hd graphic 4600 driver. may i have install other feature on window server 2012? Thanks you so much.

hi admin, my snmp device is pCOWeb - CAREL, there are three types of output: boolean, integer and analog. I cannot change type of these output. Can you give more advise. Could DAQ not change typse of output writting?? Thanks admin.

hi admin, I tested and this is my result (with private community and with a tag): - with SNMP explorer tool: + write this tag with long type - success + write this tag with float - failed - with Kepserver quick OPC client: + write this tag with long type - success + write this tag with float - failed - with DAQFactory (async & sync): + write this tag with analog output - failed + write this tag with discrete output - failed + write this tag with string output - failed i don't know what to do with DAQ, nothing happen, no error message... thanks admin

Hi admin, I config KEPServerEX (SNMP driver) to read/write a snmp device and i have a tag with LONG type. I config a channel (asyn read) in DAQ to read this tag and successful, but when i config this channel as output (analog output or discrete output) to write new value, i failed. Nothing happen with DAQ and my tag. I also use code myChannel = value but unsuccessful. after that, i try to use a opc quick client of kepserver to write this tag and it successful. What do i need to config DAQ to write a opc tag with long type? Please help me. Many thanks, ThuatNM

Hi admin, the help document in daqfactory say that: "Tip: If you would like to remove a device from the list of possible devices displayed when creating Channels, simply rename (or delete) the .dds file associated with the device(s) you would like to remove to something without a .dds extension. DAQFactory only loads devices with a .dds file associated with them." - 17.1 Device Overview What does this mean, maybe some thing wrong with .dds file? is it take long time to create new document ctrl? My ctrl file is almost completely . I only want to clean something not useful. Many thanks.

Oh, many thanks to admin, it's work. I can read a CHAR and VARCHAR column. Do you know why it' not work when a column is format as TEXT.

Thanks to reply, i has just tested with your code but i can't read a TEXT value, it's return 0. Please see some attached file.
