1 Overview
SMI200 is a programmable controller with 2-line 32-character LCD display designed for a wide
variety of applications in industrial and building automation from simple display to complex process
control functions.
The controller can operate as a master or slave in a Modbus network over RS485 interface. In or-
der to be integrated in a Modbus network, the controller has to be configured and programmed with
the akYtec ALP software included on the USB stick.
See ALP Help for further details about device configuration and programming.
The configuration can be carried out with device front buttons over the system menu as well (see
sections 5, 6).
The connection with akYtec ALP running on the PC can be established over the USB interface
(Fig. 1.1). When being connected to PC over USB, the device is powered by USB and does not
need additional power supply.
User application includes the logic program created as a function plan as well as the device config-
uration.
1.1 Functions
The device has the following basic functions:
– 2-line 32-character LCD display
– 6 function buttons on the front panel
– Master or slave in a Modbus RTU/ASCII network over RS485 interface
– Easy mounting in Ø22.5 mm borehole
– Error indication
– Real-time clock
– Free programming with akYtec ALP software
– Micro-USB programming interface
– Quick replacement
1.2 Design
The device is designed in a plastic enclosure for panel mounting (see 4 “Installation”).

5 Display and function buttons
The device and process parameters can be viewed and edited (if available) on the display using
the function buttons. For device parameters, see section 6 “System menu”.
To view or edit the process parameters, display forms have to be programmed with different dis-
play elements. Jump conditions have to be created to let an operator to switch between the display
forms using the function buttons. Jump condition can be a button event of a variable event. For
further details about display elements and jump conditions use Help in akYtec ALP.
There are editable and not editable display elements thus the display can be used in view or edit
mode.
In the view mode (default):
−use and buttons to move between lines
−use button to enter the selected level, and button to exit it
To edit the parameter, press the button . The first editable element on the display starts flash-
ing. Use and buttons to change the value. Use the button combinations to move between
characters:
−+ – one character to the left
−+ – one character to the right
To save the new value and edit the next parameter, use the button .
To reset the parameter to its previous value and exit the edit mode, use the button .
To save the new value staying in the edit mode, use the button . The next editable parameter
will be displayed selected.
The last changed parameter will be shown next time when the edit mode is active.
Note:
When assigning а jump condition to the function button, don't forget that the user function will have
a higher priority than the system function.
Example:
If the and buttons are used as a jump condition for a certain display, it will be impossible to
use them to scroll the lines inside this display.
