Delta ISPSoft — 7.2.3 Input/ Output Pins of a Function Block

ISPSoft User Manual Generally, the data type of P_Var (in the caller) and the data type of FB_Var (in the function block) is the same. But for some situations, the ISPSoft allows the length of the data type of P_Var (in the caller) to be shorter or equal to the length of FB_Var (in the function block). If the data type of FB_Var (in the function block) is ARRAY, then the data type of P_Var (in the caller) has to be ARRAY and the content as well as length has to be the same as FB_Var (in the function block).
