using rto in connected components

[Mueller34]

Hello,

I am new to playing around in connected components and using RTOs in general. My question is does the RTO instruction in ccw have a timer timing bit like the TONs and TOFs in rslogix? I'm guessing this is just the input bit?

Thanks,
Eli

Yes, well, [XIC input_bit] ANDed (in series with) [XIO rto.DN]

Or is that rto.Q, I forget?

rto.q would be the done bit. I just wasn't sure if ccw had a TT bit like in rslogix 500. the TON has the REDGE bit. Which I did find that the rto has the .IREDGE bit which is pretty much what i was looking for

I believe you have to make your own form of a TT bit in CCW.

Cf. this link.

TL;DR

.IREDGE in CCW is the same as .EN in RSLogix 500.

There is no equivalent in CCW for .TT* in RSLogix 500.

* .TT is "Timer is Timing;" see this link and image below.

See also CCW Trend below demonstrating that .IREDGE is not analogous to .TT, because .IREDGE does become 0, like .TT does, when timer completes.
