Program example
In this program, the logical negation is obtained using each bit of word [unsigned]/bit string [16-bit] data stored
in a device specified in
type of data stored in a device specified in
1) Function without EN/ENO(NOT)
[Structured ladder]
g_word1=16#AAAA
[ST]
g_word2:= NOT(g_word1);
2) Function with EN/ENO(NOT_E)
[Structured ladder]
g_bool1
[ST]
g_bool3:=NOT_E(g_bool1,g_word1,g_word2);
, and the operation result is output to a device specified in
