Allen-Bradley MicroLogix 1100 Instruction Set Reference Manual

Publication 1763-RM001C-EN-P - October 2009
How to Use 40kHz PTO/PWM of MicroLogix 1100 Series B Controller 575
For example, assume the PTO:0.OF value is 20000 and a user wants to set
that value to x2 (twice) using the MUL instruction. If S2/14 is cleared and
S:5/0 bit is not cleared after execution of the MUL instruction, then the
result will be 32767 and Math Overflow Error will be reported at the End
of Scan.
ADD Instruction Workaround Example: PTO:0.OF(40000) =
PTO:0.OF(20000) + 20000
