Chapter 7 Program
7-10
Remark
(1) Since instruction PUT (Function Block PUT_DWORD) is used at scan program example of XGK (XGI/XGR) series, while
input contact point is On, data is transmitted into HSC module. So, if data is changed, it is transmitted into HSC module
automatically.
(2) If you program as follows, its operation become different with program example.
(a) If input contant point of function block is on and execution of function block is compete, ‘DONE’ becomes 1. Namely, front
function block and back function block are not executed simutaneouly and from left to right, they are executed sequently.
(b) If input variable of function block is set uncorrectoly and error occurs, ‘DONE’ doesn’t become 1. Namely, if error occurs at
front function block, back function block is not executed.
(3) Integer can be inserted into ‘MADDR’ instead of global constant. The operation of the following program is same with that of
the front example.
(a) For integer corresponding to global constant, refer to Chapter 6.
(b) On the next program example, scan program example using integer (constant) is omitted.
