This is how I have my RS485 ladder setup.
I have tried as suggested splitting my setpoint between 2 x INT16 value to write to 1010 and 1011 but I still get noting on the pressure controller.
Pressure from the controller is being read correctly as a REAL value
1. You are skipping row 0. First Data tables row is 0. In your case, limits must be 0 ... 299.
2. ML9 returns the FIRST row where the InvoiceNO is found, or returns -1 if not found; not the number of times InvoideNO is present in the DB.
3. You don´t need to use find extended FB.
Here is the code Written for above
Logic written to Find row containing Invoice Number which Already exists in DataTable or not
Ex If ML10 = contains Invoice No=40625
ML9 and ML8 Should retrun the no How many times it occured in Data Table that is
0 for No Row contains 40625 ,1 For 1 Row Contains
but i am Getting Some other number may be 3 or 4
and some times
0 if it exists
request your help to diagnose the cause
