Instance Method Details

#get_available_for_group ⇒ Object

Returns a bitmask of ports that are available for grouping. For example the value 5 or 0b0101 means: Port A and port C are connected to Bricklets that can be grouped together.

end

#get_identity ⇒ Object

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’ or ‘h’ (Bricklet Port). A Bricklet connected to an :ref:‘Isolator Bricklet <isolator_bricklet>` is always at position ’z’.

The device identifier numbers can be found :ref:‘here <device_identifier>`. |device_identifier_constant|

end

#get_monoflop(pin) ⇒ Object

Returns (for the given pin) the current value and the time as set by BrickletIndustrialDigitalOut4#set_monoflop as well as the remaining time until the value flips.

If the timer is not running currently, the remaining time will be returned as 0.

end

#set_group(group) ⇒ Object

Sets a group of Digital Out 4 Bricklets that should work together. You can find Bricklets that can be grouped together with BrickletIndustrialDigitalOut4#get_available_for_group.

The group consists of 4 elements. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

Each element can either be one of the ports (‘a’ to ‘d’) or ‘n’ if it should not be used.

For example: If you have two Digital Out 4 Bricklets connected to port A and port B respectively, you could call with “[‘a’, ‘b’, ‘n’, ‘n’]“.

Now the pins on the Digital Out 4 on port A are assigned to 0-3 and the pins on the Digital Out 4 on port B are assigned to 4-7. It is now possible to call BrickletIndustrialDigitalOut4#set_value and control two Bricklets at the same time.

end

#set_monoflop(selection_mask, value_mask, time) ⇒ Object

Configures a monoflop of the pins specified by the first parameter bitmask.

The second parameter is a bitmask with the desired value of the specified pins. A 1 in the bitmask means high and a 0 in the bitmask means low.

The third parameter indicates the time that the pins should hold the value.

If this function is called with the parameters (9, 1, 1500) or (0b1001, 0b0001, 1500): Pin 0 will get high and pin 3 will get low. In 1.5s pin 0 will get low and pin 3 will get high again.

A monoflop can be used as a fail-safe mechanism. For example: Lets assume you have a RS485 bus and a Digital Out 4 Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds and pin 0 high. Pin 0 will be high all the time. If now the RS485 connection is lost, then pin 0 will turn low in at most two seconds.

  send_request FUNCTION_SET_MONOFLOP, [selection_mask, value_mask, time], 'S S L', 8, ''
end

#set_selected_values(selection_mask, value_mask) ⇒ Object

Sets the output value with a bitmask, according to the selection mask. The bitmask is 16 bit long, true refers to high and false refers to low.

For example: The values (3, 1) or (0b0011, 0b0001) will turn pin 0 high, pin 1 low the other pins remain untouched.

If no groups are used (see BrickletIndustrialDigitalOut4#set_group), the pins correspond to the markings on the Industrial Digital Out 4 Bricklet.

If groups are used, the pins correspond to the element in the group. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

Running monoflop timers for the selected pins will be aborted if this function is called.

end

#set_value(value_mask) ⇒ Object

Sets the output value with a bitmask (16bit). A 1 in the bitmask means high and a 0 in the bitmask means low.

For example: The value 3 or 0b0011 will turn pins 0-1 high and the other pins low.

If no groups are used (see BrickletIndustrialDigitalOut4#set_group), the pins correspond to the markings on the Industrial Digital Out 4 Bricklet.

If groups are used, the pins correspond to the element in the group. Element 1 in the group will get pins 0-3, element 2 pins 4-7, element 3 pins 8-11 and element 4 pins 12-15.

All running monoflop timers will be aborted if this function is called.
