I have my program and HMI setup but I am looking for some improvements. My setup uses an AB Micrologix 1000 and AHMIv35 to control IO based on time of day and input status. There is no internal clock on the 1000, a limitation I was not aware of until I started programming with the device. Where this is for home use and practice, I don't have the budget for another PLC processor. I have user keypad entry to set hours, minutes and seconds to three separate integers in memory. Can anyone advise a way of sending the PC time of day to the PLC? Once I have the data to the PLC I can format for use with my program. I only need one instance of sending TOD to the PLC, once time is set the counter on the PLC will be sufficient for keeping time. A drift of seconds or even minutes will not affect my process. Thanks for the help.
