3 Control of alphanumeric HMIs
This chapter describes how to control Jetter AG HMIs with text display from
within the application program of a JC-3xx or JC-4xx control system. It also de-
scribes the registers used to parameterize the display functions. The controller
provides the following display options:
■
Displaying text strings
■
Displaying the contents of variables
■
Scanning the HMI keys
■
Switching the HMI LEDs
■
Monitor function
The display feature is part of the STX language set.

3.1 Registers
INFO
Limitations
The settings made in the given registers take global effect,
meaning they impact all functions for controlling HMIs. If differ-
ent settings are used in several tasks of the application pro-
gram, then these settings may impact each other.
The registers are clustered into one register block. The basic register number of
this block depends on the controller.
Basic register number
220000
In this chapter, only the last 4 digits of a register number are specified, e.g.
MR 2838. This is the module register. Add the basic register number of the corre-
sponding device to determine the complete register number, for example 222838.
