How do you make the Remote Date and Time in PLC transition from zero to non-zero??? I have Controllogix with Panelview Plus 1000. I don't know how to make the Remote Date and Time tag go high!!!
Oh no!!! What will you do???
Seriously, do you have a tag assigned to Remote Date and Time in Global Connections?
If so, you are halfway there. Once you have the tag assigned, you would make it go high with PLC logic, same as you would any tag.
If you follow the link that I posted in the post you quoted, there is an example program (in pdf) for Logix 500 on how to trigger the Remote Date and Time tag. I know you are using Logix 5000, but the same logic can be applied.
Alternately, you can have the bit set high not off of user interaction, but off of an examination of PLC system time. For example, at my plant, we shift change at 6AM and PM. So I have a routine where I execute a GSV of WallClockTime into an array of 7 DINTs, DateTime[7].
DateTime[3] is the hours, so when DateTime[3] = 6 or 18, then I one-shot latch the Remote Date and Time bit. I leave that bit latched for 10 seconds then OTU it.
For the duration of that on-time, the values in DateTime[0-5] (which are assigned to Remote Year, Month, Day, Hour, Minute, and Second, respectively) are moved into the PV+ system time, keeping it synced to the PLC clock.
Good luck and HTH
