SYSMAC NX1P2 Writing to NB HMI Local Memory

2 posts in this topic

Any way for the PLC to write data directly in to one of NB HMI's local memory addresses?

Say I want to write a value of "13" in to HMI's Area/Variable LW Address 100. Is this possible without using a macro?

Thanks.

Yes, but the PLC doesn't initiate it. You can program LW100 to take the value of say D100 using a data transfer object in the common window. Make the source D100 and the destination LW100. You'll need to give it a trigger bit so it runs constantly. I would map the 1 second clock pulse from the PLC to a bit that the HMI can address and then it will constantly update LW100 with the value of D100.
