3.4.1.1 Importing the MLx-HMI Task
The first step to set up the HMI is to create the MLx_HMITask inside the
RSLogix Project. To do this, right-click on Tasks in the Control Module
Organizer and select “New Task”. Then, enter the task properties as
shown in Fig.3-19 "MLx_HMITask Properties".

Next, right-click on the task, choose “Import Program”, and select the
provided HMIUpdates.L5X file. After importing the task, it should appear in
the Control Module Organizer as shown in Fig.3-20 "HMI Task in Control
Module Organizer".

The Period of 20 ms and Priority of 10 are recommended
default settings. The Period and Priority could be made
lower if the responsiveness of the HMI (particularly while
jogging) seems slow, but this will increase the CPU Load.
Similarly, the Period and Priority could be made higher if
CPU resources are scarce, but this may lead to some lag or
poor performance (particularly while jogging).
