We'll be looking at how to access a PLC's word registers to the bit level from an HMI, such as with a bit lamp or a switch on the HMI screen, particularly where the HMI's driver does NOT support bit-level access to the particular PLC data type.
We'll be using the EasyBuilder HMI simulator on a PC, connected to a MicroLogix PLC.
If you'd like to try out this functionality or other features of our HMIs, please visit Rohtek Automation at rohtekautomation.com, and download the free EasyBuilder software. You can make an HMI project on your PC, connect to your PLC and run the online HMI simulator as often as you like for up to 10 minutes at a time.
