The ASDA-A2 series provides many motion control functions, such as E-Cam, Capture, and Compare. The data array can keep data for E-Cam, Capture, and Compare with a maximum of up to 800 records. Access to Data Array: There is one index, P5-11 working along with two read/write windows, P5-12 and P5-13 for accessing the data array. For some external controllers resending data several times while communicating, it is better to put the index P5-11 before each read/write operation. In other words, set the desired read/write addresses by using P5-11 and then read/write the data through P5-12 or P5-13. For example, to write three consecutive numbers of data (100th, 200th, 300th), and save them into the address 11, 12, 13 of the data array, the operation steps are as follows: 1. When writing data through the keypad: Use P5-12, read/write window#1 because P5-13, read/write window#2 does not provide this function. 1) Set first address: Set P5-11=11 (the first address) 2) Write data: Set P5-12=100. (This is the first written data, 100th data and it is saved in address 11, i.e. P5-11. After the write operation is completed, the address of P5-11 will increase 1 automatically to address 12.) Set P5-12=200 (This is the second written data, 200th data and it is saved in address 12, i.e. P5-11. After the write operation is completed, the address of P5-11 will increase 1 automatically to address 13.) Set P5-12=300 (This is the third written data, 300th data and it is saved in address 13, i.e. P5-11. After the write operation is completed, the address of P5-11 will increase 1 automatically to address 14.) The user can then read the addresses 11, 12, and 13 and check the written values. 2. When reading data through the keypad: Use P5-13, read/write window#2 to read consecutive data. 1) Set the first address: Set P5-11=11 (the first address) 2) Read data: When the display shows P5-13: Press SET key the first time and the display shows the 100th data saved in address 11. Press MODE key to exit P5-13. Press SET key the second time and the display shows the 200th data saved in address 12. Press MODE key to exit P5-13. Press SET key the first time and the display shows the 300th data saved in address 13. Press MODE key to exit P5-13. Please note that when using P5-13 to read data each time the address of P5-11 will increase 1 automatically. This indicates that using P5-13 is reading consecutive data. However, when using P5-12 to read data and the address of P5-11 remains the same, it indicates that using P5-12 is not reading consecutive data. The operation steps for reading or writing data through communication are similar to the steps when using a keypad. The functions of P5-12 and P5-13 are also the same.
