This module type is always available. No license is needed.

The function of this module type is to read and output values from a 2-column table depending on a key signal. For example, one possible application is the translation of error codes into easily understandable error descriptions. Numerical quantities or texts can be processed.

The table contents are transferred to a so-called profile and saved. The entry into the profile can be done line by line manually or via copy & paste from a table, e.g., in MS Excel.

A profile always contains only one table.

A key selector signal is used to select the row of the table by comparing the value of this signal with the entries in the Key table column. The value from the Value column is output as an analog value (numeric or text). If the key selector signal's value does not exist in the table, then a default value is output.

Exactly one profile can and must be selected per lookup table module.

The figure below shows the principle of the profile-based lookup table module.

The module offers 10 output signals as standard, each of which can be individually linked to a key selector signal. You can increase or decrease this number. This allows you to serve multiple applications with one lookup table module.

If, for example, a plant contains 10 drives, each of which sends an error message with an error code, then create a module with 10 analog signals, one for each drive. You can then select the signal with the error message from the corresponding drive as the key selector signal. This way, you can visualize the error messages in plain text for all 10 drives, e.g., in ibaQPanel.

The profile-based concept also offers the possibility of know-how protection and license-controlled use. With the know-how protection feature in the I/O Manager of ibaPDA, you can prevent the lookup tables from being viewed or modified. Furthermore, the use of a lookup table can be bound to certain license numbers (dongles) by means of the profile property.
