F42_BADD2

Redundant instruction

NOTE

This is a redundant instruction. It is replaced by: FP_ADD_BCD

The 4-digit BCD equivalent constants or 16-bit areas for 4-digit BCD data specified by s1 and s2 are added together if the trigger EN is in the ON-state. The result is stored in d.

Example

(1) Example value 16#4321 (BCD)
(2) Example value 16#1234 (BCD)
(3) Result value 16#5555 (BCD) if trigger is ON

Parameters

Input

s1 (WORD): Augend, 16-bit area for 4-digit BCD data or equivalent constant
s2 (WORD): Addend, 16-bit area for 4-digit BCD data or equivalent constant

Output

d (WORD): Sum, 16-bit area for 4-digit BCD data

Error flags

sys_bIsEqual (turns to TRUE for one scan): if the calculated result is 0.
sys_bIsCarry (turns to TRUE for one scan): if the result exceeds the range of 4-digit BCD data (overflow).
