Plc

Hi all,
I am looking for a plc whatever the brand is but it must have a built in real time clock. The additional feature could be like this
1- Expansion I/O module
2- Built in Analog Inputs
3- Potentiometer
4- Optional memory cartridge

will you please help me out if you have any PLC in your mind that has all the above features.
thanks

Telemeqanic Twido or Tri-Plc.

Thanks,
we are already using TWIDO PLC, TWDLCA24DRF. but it has no internal real time clock. you will have to use a separate module for this.
