I have recently taken a new job and my first project is a fairly simple one. I am going to turn on a pump and chiller an hour before production starts. In the future other items may be added to the process...air compressor, extruder heat etc. I am involved at the start of a new process with all new equipment in its own building with management that wants processes automated.
At this time I dont need but 16 I/O with a RTC (real time clock). The company has decided to standardize on AB either MicroLogix or the SLC at this time.
What I plan to do is program the plc to look at day of week..ie 0=Sunday 1=Monday etc and turn on the chiller/pump for that day if scheduled. I will need to use an Operator Interface to modify for holidays and unscheduled work days. I may also schedule off time and in future more items will be added to the process.
I looked at the MicroLogix 1000 but couldnt see where RTC was available so I am looking at the ML1200 with RTC and a MicroView as the operator interface. I may up to an ML1500 to get 2 ports and more expansion options but not sure yet if the cost will be a factor.
My Question
Will the ML1200 with RTC module with the MicroView (2707-MVP232) offer the ability to create screens to modify the day to day needs? I have read thru the manual for the MicroView and it looks to me like it will work but I wanted to verify it. I believe the ML1200 with an RTC should allow me to use a compare instruction to verify time on a day to day basis.
