1.2 Description
The DICON touch is a universal process and program controller with 4 control channels, which
displays information on a vibrant display and is operated intuitively with touchscreen.
Up to 4 control channels are available via the tried-and-tested JUMO control algorithm with two
possible optimization variants. These enable a simple and highly-accurate startup. Even mul-
tiple-zone control, cascade control, or other complex control tasks are therefore possible.
In the following block diagram, the various hardware options of the modular hardware concept
are depicted. 4 analog universal inputs and up to 8 external inputs can acquire a variety of
physical measured values with high precision. Thanks to different output variants, the actuators
can be controlled directly in the device, either in an analog manner or digitally. These can be
expanded further through external digital outputs. To communicate with higher-level systems,
interfaces such as Modbus (master/slave), PROFIBUS, PROFINET-RT, or Ethernet with web
server, can be used.
To ensure secure process operation, the device has password-protected user administration
with individual assignment of rights for different levels or control commands. Screen masks for
controllers, program generators, recording, and for overview screens are ready-made and
available. Four individual process screens can be created as desired using the configuration
software. Important analog and digital process values can be saved in a tamper-proof manner
with the recording extra code, visualized graphically, and exported to PC in a tamper-proof
manner via interface or USB flash drive.
The configuration software allows for the process controller to be programmed with ease, for
math and logic coherences to be described, and for customer-specific linearizations to be cre-
ated. Additionally, tools are included for simulating external signals or the control process, or to
record for the duration of the startup.
A comprehensive alarm and limit value concept as well as flexible digital signal management
complete the "all-in-one device".
