When I press a function key the associated button on the screen blinks 2 secs later. The screen then changes under PLC control 5 secs later. Is this the kind of response time I should expect from the C-MoreMicro? I am running the latest firmware.

It is hard to say with any certainty.
Response times vary due to the number of registers on a screen, the number of registers that are used globally (Screen change, etc.), and any noise present on the communication lines. Also relevant is the PLC scan time.
I'd check for noise on your power and communication lines first. If you extended the cable, have any noise producing equipment nearby such as VFD/AFDs, welders, transformers, etc you might want to reroute your power or comm lines.

Scan time is less than 4ms. Few registers, 2 screen changes. Assuming clean communications, what are typical response times for screen changes and button responses?

How are you connected? Are you using Ethernet, serial? Is it a AD CPU? I have used both serial (highest setting the CPU will allow) and Ethernet with always good results.

Serial at highest setting to port 2 on DO-06DD1, DirectLogicK. What kind of response time was "good results "?

Pushing the bitmap button on the panel was just like pushing a hardwired physical button. The PLC responding immediately. There are some really smart guys in here, post your portion of the program that seems to be the problem. Someone will have the answer.

Thanks for the info on how fast the panel should respond to input. I reduced the panel program to two screens with 5-buttons on the first screen activated by function keys. The response time is still as I indicated above, about 2 secs to acknowledge a button push. I emailed the panel project into tech support. Suspect there is something wrong with my C-More Micro panel.

i haven't used the micro before, but if it is setup like the cmore screen, then you can adjust the Poll Time on the screen. you might want to check this for the delayed response.

All fixed! It was a wiring problem (my mistake) on the cable connector from the panel to port-2 on the 06. Response time now is instant.
Thanks to the forum and Automation Direct's excellent customer support.

Turns out it was not my made up 15-pin port 2 connector. Purchased 15-pin connector from AD and still got the slow button response from the C-More Micro panel. Changed the RTS and CTS delay from 100ms to 2ms on the Secondary Port Setup. This solved the problem of slow response from Port-2.
