Full Version: Micrologix 1200 Register Fill
I am trying to fill 35 words in the F8 Float Data file and I can't find a command to do it. I want to zero out the F8:0 - F8:34 words by filling them with zeros and can't seem to find anything but 35 MOV commands to do it. It says in the help that the Fill (FLL) and Copy (COP) commands can not be used in the 1200 PLC with floating point values. Anybody got any ideas?

In a series "C" ML1200 a floating point value is supported by a FLL instruction (see PDF below)

I read through the PDF and found the note you are referencing. I assume you got this off of the AB manual. The online help says you can't. It so rare that AB has conflicting documentation
I wrote it in the program and it took it so I think it works. Thanks for the help.
