PLC program wants to use the receipts the first step for a programmer is to define the receipt needed variables and declare them into the retentive memory Once defined the programmer have to link the variables to the receipt This step take place in the HMI environment When a new project is created the global function Rept_add_vars is available to the programmer Inside this procedure two functions deal with adding variables Rept_add_tyReal_par to add a float variable and Rept_add_tyDInt_par to add a signed integer variable The above mentioned functions require four parameters e The list position of variable integer from 0 to N e The name of PLC variable to be associated as defined into the PLC project e The mnemonic associated to the variable that may be either the variable name or the any other name The maximum string length is 18 characters e The measurement unit associated to the variable The maximum string length is 5 characters The function return zero if the operation is correctly handled For instance to insert the PLC variable Varl in the first position of a receipt defined as real variable with mnemonic speed and measure unit m s The result is stored into the Result variable Result Rcpt_add_tyReal_par 0 Var1 speed m s To use receipt values into a PLC program the selected receipt parameters need to be copied into the PLC The programmer must predispose this copy by inserting into the procedure
