Where are the timer enable bits and the timer timing bits? If there are none, what is typical work around?

The timer done bit would be the coil to the right of the timer box. There is no timer timing, but you can create it with a branch or another rung as shown below:
{ "data-align ": "none ", "data-size ": "full ", "title ": "CLK_TMR.PNG ", "data-attachmentid ":121568}

OK. I'll give that a try. But there is no tmr.en status bit then?

Correct, you would use the same logic that is used to the timer on another rung to a coil or add a branch that does not have the DN bit in front of the output coil so it turns on when the timer enables.

I'm trying to put up an initial power up screen to a C-More Micro with no luck. I assume I can use the first scan bit to run a 30s timer to have an initial screen display so that the appliances in the control panel have some power up time. I 've tried about 5 different configurations with latch bits, outputs, seal in's, and nothing is working. First time making either of these do anything and I'm ready to toss the whole box at this point. How would you accomplish this? I 've attached a word doc with screenshots of what I wrote.
I'm using the first scan bit because there is no MCR or any other status bit to program any power on period with (so that the initial speed selection screen is not displayed directly and operators cannot just start pushing whatever). This is a precision grinder that I added a GS2 AC drive and Click Koyo to. The grinder will have pre-programmed speeds in the C-More micro that will run the drive via analog speed reference out of the Click PLC.
Any ideas would be appreciated.

There's no need for the first scan one shot. First scan bit is a one shot bit by design. I'm not sure if that's your problem, but it's the first thing that jumped out at me.

I removed it and the timer still will not time.

I see it now. Click positive transition contacts do not work like AB one shots. They 're not used as a separate instruction. In rung 13, remove the one shot and change the T2 NO contact to a positive transition. Remove the one shot in rung 1.

Stick a counter in with a first scan bit just to see if the first scan bit is ever activating

Figured it out. Online edits do not produce a first scan bit. Banging my head against the wall currently.
