I want to turn on a coil at a time specified by an HMI time function entry variable (HH:MM). I thought it should be easy, but I need help. The value of this variable doesn't appear to me to be either RTC or anything else I can decipher. For example: 00:00 = 0, 00:10 = 16, 01:00 = 256, 12:00 = 4608. What is this value? Or how can I compare this to SI 32 (current time HH:MM)?
I can't find any information on HMI timer function variables in the help document. But I did find a very promising example on the 'Clock: Indirect Function Example' page. Unfortunately the help document is incorrect -- the indirect time of day function in the V130 doesn't automatically appends a mysterious (undocumented) second operand -- which I assume is a stop time, and which I can't have.
HELP!!
