6.2Component Items (Icons) of the Program

The types of input signals are the Digital Inputs, Analog Inputs and AS-interface bits. The icons can be found under the Input Signals Accessories Toolbar “IN” at the left of the FBD base.

1)The digital signals can be placed on the Input rectangles at the left of the FBD base or on the base itself. Each icon functions in the same way. The different icons have been developed to aid in the documentation and understanding of the program. Use an input icon that corresponds to the actual input device to be connected to the α series. The names of the signals will appear when the mouse arrow is placed on the icon.

2)The analog and temperature (from AL2-2PT-ADP or AL2- 2TC-ADP adapter) signals can only be placed in Input Rectangles I01 - I08.

6.2.3Outputs

Output signals is the Digital Outputs and AS-interface bits. The icons can be found under the Output Signals Accessories Toolbar “Out” at the left of the FBD base.

1)The system outputs should be placed in the output rectangles on the right side of the FBD base. Outputs placed outside the rectangles will act as neutral blocks. The outputs blocks have one input pin and one output pin that can connect to other function blocks or outputs.

2)4 AS-interface outputs, “LINK out” icon A01 - A04, are available when using the following location. These Outputs can be placed anywhere on the FBD base and will not count towards the number of system outputs.

α2 Series

AL2-14M*-*, AL2-24M*-* model

6.2.4Operation Keys

There are eight signals that correspond to the front panel keys and these signals may be used as additional digital inputs. These are the ESC, OK, “+”, “-”, , , and keys. Press the front panel keys while the α series is in Run mode to active the signals.

These keys may be placed only on the FBD Base and can be found in the Input Signals Accessories Toolbar “IN”. The names of the signals will appear when the mouse arrow is placed on the icon.

6.2.5System Bits

These System bits act as digital inputs and can be placed on the FBD base. The system bits have the following set functions. These bits can also be found under the Input Signals Accessories Toolbar “IN”. The names of the signals will appear when the mouse arrow is placed on the icon.
