ISPSoft User Manual POU Name : Users can type a POU name in this box. (a) Special marks and spaces can not be used. For example, *, #, ?, \, %, @, and etc. can not be used. (b) A POU name is composed of thirty characters at most. Users have to notice that a Chinese character occupies two characters. (c) Underlines can be used, but they cannot be used continuously or put at the end of a POU name. For example, “POU_1” is a legal name, but “POU__1” and “POU_1_” are illegal names. Function Return Type: Choose the data type of return values for Function-type POUs via button. If the setting is VOID, there will be no return values, which also means no output parameters. Task :
