RS500 Writing to multiple registers

weyenbergc · Aug 3, 2010

Is there any way to write a zero or to clear multiple registers in RSLogix 500?

I want to set N46:208 - N46:254 all to zero without having to write 47 move commands.

Thank you.

Yep. It's called the Fill File command:

FLL
Source: 0
Destination: N46:208
Length: 47

Awesome, thank you Okie

This will come in handy in the future also.

If you want to put an little pinache into it, you could XOR a file with itself, and store it in itself.

Another way up the mountain.

speaking of XOR

Here is a fun one:

A:= A XOR B
B:= A XOR B
A:= A XOR B
