LED DISPL AY
Individual LED display (Register 4x0014 = 0)
The colour and brightness of LEDs can be controlled individually via Modbus.
With the registers 4x0015 to 4x0019 (LED x mode, x=1...5), the corresponding display status of the LED can be set
(continuous light, various flashing options) or the LED presence buttons can be as Signed.
Registers 4x0020 to 4x0024 (LED x colour, x=1...5) can be used to set thecolour and brightness of the LED (see table).
The tens stand for the colour while the units stand for brightness. For colour and brightness allocation,
the value 100 refers to the corresponding LED colour register (4x0025 to 4x0039) with the option of individually assigning
the three colours red, green and blue.
The LED displays are switched on and off individually through the MODBUS telegram "Function 05 Write Single Coil".
The adjacent register settings correspond
to the following example of various operating
fault messages:
LED 1 red
Alarm – flashes quickly
LED 2 yellow Warning – flashes slowly
LED 3 white Operation
LED 4 green Operation
LED 5 white
Presence including
connection with button
LED bar graph display (Register 4x0014 = 1 to 4)
The LEDs are connected in a display chain and show the value recorded in the register 4x0013 (bar graph value) in colour.
Individual intermediary stages are displayed by changes in brightness.
The bar graph colour choice can be selected via the register 4x0014 (bar graph mode) and can be set individually
via the LED colour register (4x0025 to 4x0039) if required.
The adjacent register settings correspond
to the following example of a user-defined
traffic light display:
LED 1 red (colour register)
LED 2 yellow
LED 3 yellow-green
LED 4 green
LED 5 green
POTENTIOMETER AND ROTWARY SWITCH
The potentiometer setting is recorded in the range from 0...100% and is emitted via the register 3x0005 (setpoint potentio-
meter). The rotary switch setting (optional) can be queries via the register 3x0010 (rotary switch) in the positions 1 to 5.
