This chapter contains information on how to control HMIs with text displays
using the application program in a JC-120MC controller. It also describes the
registers used to parameterize the display functions. The controller provides
the following display functions:
 Displaying texts
 Displaying the contents of variables
 Scanning the HMI keys
 Switching the HMI LEDs
 Monitor function
In this manual we proceed from the assumption that the user is familiar with
the following STX instructions DisplayText(), DisplayText2(),
DisplayValue(), and UserInput(). For a more detailed description of the
instructions mentioned above refer to the online help included in the
programming tool JetSym.
