This function updates the pointer of a table within a list of tables. A command table is an ordered list of commands used to direct the actions of individual axis or groups of axes.
The function searches in the list i_pstListOfCmdTables from 1 to i_udiNumberOfCmdTables for the i_diCmd and updates the pointer pstCmdTable in the list with i_pstCmdTable.
This update must be performed if an online change takes place. If the input i_xOnlineChange is set TRUE it is recognized by the function block. As default, the output of the FB_DetectOnlineChange function block should be connected to the i_xOnlineChange input.
