Warning output during synchronization
Regarding the warning output while the inter-module synchronization function is enabled, the update timing for ALM LED,
'Warning output signal' (XE), 'Warning output upper flag' (Un\G36), and 'Warning output lower flag' (Un\G37) are changed as
described below.

(1) ALM LED turns on when a D/A conversion is completed (during warning detection).
(2) 'Warning output signal' (XE) is refreshed at the start of the synchronous interrupt program.
(3) 'Warning output upper flag' (Un\G36) and 'Warning output lower flag' (Un\G37) are refreshed at the END processing.
