Neq (NOT eqUAL)

This instruction will compare the value of Source A to Source B, to see if they are NOT equal.

If they are NOT equal then the rung is evaluated as true, otherwise the rung is false. Source A

must be an address. Source B can either be a program constant (integer only) or an address.
The NEQ instruction executes in 15µs and requires 44 bytes.
Following is a list of the data points that may be used with NEQ instructions:

Inputs
Outputs
Timers (preset & value)
Counters (preset & value)
Ladder variables
C variables
Diagnostics
Alarms

LeS (LeSS THAN)

This instruction will test to see if Source A is less than Source B. If Source A is less than Source

B then the rung is evaluated as true, otherwise the rung is false. Source A must be an address.

Source B can either be a program constant (integer only) or an address.
The LES instruction executes in 15µs and requires 44 bytes.
