Data source 2 Word/Double word
Explanation:
1. The instructions are used to compare the value in S
1
with that in S
2
. Take the instruction
AND= for example. When the comparison result is that the value in S
1
is equal to that in S
2
,
the condition of the instruction is met. When the comparison result is that the value in S
1
is
not equal to that in S
2
, the condition of the instruction is not met.
2. Only the 32-bit instruction can use the 32-bit counter.

Example:
1. When X0.0 is ON and the current value in C10 is equal to 100, Y0.10 is ON.
2. When X0.1 is OFF and the value in D0 is not equal to -10, Y0.11 keeps ON.
3. When X0.2 is ON and the value in (D11, D10) is less than 678,493, or when M3 is ON, M50
is ON.
