  1. I am working of Ethernet my v570 plc is connected to one PC address through port 0 port 1 and port 2 via listening mode. now my problem is that when PLC open the 2 port at time the PC get confused it stop to working. my working is that once PLC is open the port the PC is close the port. My questions is that the conflate we are facing is either PLC side or at PC side.
  2. Hi, We are developing a project using Vision 570 PLC having 12 analog input and 128 Digital IO. We want to establish direct communication with vision 570 so we can read & write the specific MBs, MIs, MLs, and Mfs,. We develop the program accordingly vin VB6. Previously we have down loaded sample communication file from net as per your suggestions.That file was working properly. We have used sam logic in our VB program which was running. Due to some problem in our PC we had to format hard disk after that we have down loaded same sample file from the site now it is not working showing that compile error . During run time the program reads private mcomdriver as uncmdrv1.clscommdriver private withevents methservice as umcmdrv1.clsethservice It show compile error at this point it dosen't proceed further pl. give us solution on the subject so that we directly access the PLC which can be directaly incorporated with the variable defined in VB6 Thanks & regards

  5. Dear sir, We are developed the new weighing conveyor using LC3 & LC1 and vision 570. we are facing the problem that our weight is not showing correct value & the fluctuation is very high. The four load cell are calibrated separately calibration is store in the eeprom. when i see the value of each load cell the loadcell connected to LC1 get fluctuated very high from negative to positive. due to that we are not able to get the correct reading. As per the sample program we use the filter & rounding FB but still the fluctuation same. We wright separate ladder for weighing but problem is as it is. please tell us the solution how i can get the stable reading. thank mahesh joshi
