What instruction would you use to compare 2 values for a greater than, less than or equal to condition in a Compact E984-258 using Proworx Nxt?

You would use the TEST Instruction (see below)


If 40001 is greater than 40002 top node output will come on
If 40001 is equal to 40002 middle node output will come on
If 40001 is less than 40002 the bottom node output will come on

This Instruction is only available with the high end PC-E984-258/265/275/285 Compact PLCs and not available in the low end Compact PLCs (You would use the SUB Instruction in the low end Compact PLCs).

Proworx software is obsolete and it is recommended to upgrade hardware to the M340 with Unity Pro. With this you will be able to import program and also use the Compact to x80 I/O cables for the upgrade.
