Hi all, Having a problem saving the calibration from loadcell unit IO-LC3 with the V350 TRA22. I perform the steps shown in the example loadcell application and when it comes to saving the calibration the loadcell command status is 0 (busy) for a few seconds before returning status message 6 Communication Error (I/O module does not exist). I performed the calibration steps separate from the saving and they work fine. I found that if I manually change (in test mode) the command status of the loadcell back to 1 then the loadcell continues to function correctly and occasionally holds the correct calibration on power down and reboot but it isn't consistent. Wondering if anyone else has had this problem and can suggest a fix? Cheers, Innov

Hi Ofir, I've already setup the system using Indirect addressing. I'm not familiar with data tables but will look into them. Thanks for the pointer Cheers, Innov

Hi all, I'm using a V350 with the TRA22 expansion and an Enfora Modem. I was looking to set up the SMS send function so that a user can select the phone numbers to which the message is sent? I was hoping there was a way to link the phone book indexes to an array of MB's that the user can toggle on and off to send the message to a relevant number. I've had a look in the help but cant find anything hoping someone can tell me if this is possible and if so point me in the right direction? Cheers, Innov

Hi, Came up with a workaround I just multiplied the SI 32 (DDMM) by 10000 then adding in SI33 (YYYY) and performed a NUM to ASCII conversion and this gave the date that can be stored as a filename. Might help someone in the future Cheers, Innov

Hi, Just wondering if anyone can help I'm using a V350 with TRA22 expansion. I'm trying to use the date as a file name for saving a CSV excel file? Currently I use the RTC (dd/mm/yy) to ASCII and save the result in an ML and try to use this as an indirect input into the delimited line but this gives status error 2: Fail to Open File. I think its to do with the "/" that gets stored in the ASCII number, as i tried experimenting with this using constant text and got the same error status. I'm wondering if there is a work around for this? I think i can use either vectors to fill in the date using the relevant SI bits(32 and 33) but im not sure how to fill up the vector correctly? Or I could use the String Remove function to remove the "/" from the RTC to ASCII conversion but again i'm not sure how to do this correctly? Hoping someone can point me in the right direction Cheers, Innov

Hi Emil, Just thinking about it the acquire zero function should be irrespective of the calibration as your just applying an offset of a value that the user is saying should be zero unless i'm missing something? Cheers, Innov

Hi Emil, I've initially setup the configuration block in a start up bit which runs once. I then perform the calibration with set values of 10kg's and 50kg's for a max load 100kg load cell. The calibration appears to pass successfully. I don't have a set filter or rounding is this necessary? I then setup up the acquire zero fb with the same conditions that are shown in the help files along with a button press on the screen. I don't think there is a value stored in the acquire zero as i use the read zero FB and no value is shown? I've found a way round this by calibrating it with no load present but it still doesn't explain why the acquire zero FB doesn't work? I've also put in my own program to acquire the zero i'm just curious as to how to get the acquire zero FB working? Cheers, Innov

Hi, I'm new to using the unitronics PLC's and currently using the V350 TRA22 with the LC3 Load cell Expansion Block. I've calibrated the loadcells using the FB following the help files but when it comes to acquiring the zero point it doesn't set the output value to zero? I was wondering if anyone has used this before and if so is there any steps before using the acquire zero FB that need to be done? Also curious as to how the acquire zero FB applies this to the output value? Hoping someone can point me in the right direction Cheers, Innov
