Max RTO Pre RSLogix5000

[AndrewG 13]

What is the maximum Preset value for a Retentive timer (RTO) in RSLogix 5000 v20? I am trying to set up a timer for up to 24 hours long, this is 86400000 msec. When I put this value into the logic (offline) it seems to accept it, but I want to make sure there will be no issues. The Instruction Help doesn't say what the max value can be. Thanks.

RTO Preset is a DINT-type operand (see: 1756-rm003_-en-p.pdf). You should have no problem,

Conversely, it doesn't give any limitations, just that is a DINT value, and as already stated, you will have no problems with your 24-hour RTO. Sometimes you have to read between the lines when digesting the Help. Mostly it gives positive information, but occasionally, as in this case, if it doesn't give any negative indication, it's usually safe to assume a positive indication.
