Simulation and Monitoring Modes
In Simulation or Monitoring modes, it is possible to force Discrete inputs. In this case, the input symbol is displayed as shown in the above table.

 

Фильтрованный дискретный

At a Glance
Behind the Discrete input, a filter is added to reduce or even eliminate disturbances.
A Discrete input is filtered using a constant level detection algorithm (1 or 0) on the "sensor" signal, measured over a certain time frame. If the signal is stable throughout the entire detection period, the output of the symbol from the filtered Discrete input takes the value of the measured signal. Otherwise it remains unchanged.
The filtered Discrete inputs can be arranged at any smart module input.
Access
The Filtered Discrete input function is accessible from the IN window.
Parameter
The value of the parameter (between 1 and 255) entered in the Parameters window can be used to define the minimum time during which the signal must be stable. This value is a multiple of the smart relay's cycle time.
Simulation and Monitoring Modes
In Simulation or Monitoring modes, it is possible to force filtered Discrete inputs. In this case, the input symbol is displayed as follows .21

The Analog input is available on all types of smart relays supplied with DC voltage.
The analog input voltage is converted into an integer digital value by a 8-bit analog/digital converter. The whole output value is between 0 and 255.
The analog inputs can only be connected to inputs between IB and IG.
Access
The Analog input function is accessible from the IN window.
Parameter
By default, this voltage varies between 0 and 10V DC.
The type of electrical connection at the input can be configured in the Parameters window:
0 - 10 V,
The potentiometer option is selected if the input is connected to a potentiometric device powered between 0 Volts and the voltage of the smart relay.

FBD_Analog_5At a Glance
Behind the analog input, a low pass filter is added. This function is available on all smart relays supplied with a DC voltage.
The analog input voltage is converted into an integer digital value by a 8-bit analog/digital converter. The whole output value is between 0 and 255.
The analog inputs can only be arranged on the inputs between IB and IG.
Low Pass Filter
A low pass filter restores the entire input signal (frequency, amplitude and phase-shift), whose frequency is considerable lower, to a typical filter frequency, called a cut-off frequency. When the frequency of the input signal nears the cut-off frequency, the output signal, of the same frequency, becomes increasingly lower and phase-shifted. When the frequency of the input signal is equal to the cut-off frequency, the output signal is lowered by around 30%, and phase-shifted by 45°. For a frequency above and rising from the cut-off frequency, the reduction becomes greater (until it reaches total elimination) and the phase-shifting approaches 90°.
Access
The Filtered Analog input function is accessible from the IN window.
Parameters
The Parameters window is used to define:
The input voltage. By default, this voltage varies between 0 and 10Vdc.
The potentiometer option is selected if the input is connected to a potentiometric device powered between 0 Volts and the voltage of the smart relay.
The cut-off frequency of the low pass filter (between 0.06 and 88.25 Hz).

modification of cycle time
Whenever a modification is made to the cycle time, you must check or modify the cut-off frequency
Failure to follow these instructions can result in injury or equipment damage.

Special Inputs in FBD Language

 

At a Glance
In FBD, various special inputs are available:
Button,
Discrete constants,
Numerical constants,
Summer time,
Blinking for 1 second.
All these inputs can be accessed from the IN window.
These inputs cannot be inserted in the input squares of the diagram sheet.
Button-type Inputs
Button-type inputs correspond to the keys available on the front panel of the smart relay. These inputs can be inserted in an FBD diagram and, in Simulation and Monitoring mode, can simulate contacts.
Discrete Constant-Type Inputs
There are two types of Discrete constants: The 1 constant and the 0 constant . These two constants can be used to set the function inputs to 1 or 0.
In Simulation or Monitoring modes, you can force these inputs in the reverse order. The symbol then appears in red.
Numerical Constant-Type Inputs
The numerical constant NUM is an integer with a value between -32768 and +32767.
This constant can be used to set values to the functions’ non-connected inputs:
GAIN,
COMP IN ZONE,
TRIGGER.
The value of the constant can be set in the Parameters window.
In Simulation or Monitoring modes, it is possible to modify the constant.
Summer Time Input
The summer time input function is active throughout summer time, and inactive throughout winter time .
NOTE: To confirm this function:
display the Program configuration window: Edit → Program configuration,
select the Date format tab,
check the Activate the summer/winter time change box,
define the dates when the time change takes place:
Either using one of the predefined geographic zones,
Or by manually configuring the date (month/Sunday).
