Processing is assigned to each task as below: When 2-area measurement is performed (*3) Calculates Area 1 displacement value Calculates Area 2 displacement value Calculates the difference (=Thickness/gap) between TASK 1 and TASK 2 Unused (*2) When measurement other than 2-area measurement is performed Measurement result (*1) Unused (*2) Unused (*2) Unused (*2) TASK1 TASK2 TASK3 TASK4 *1: The result is a thickness distance value when the thickness measurement is set. other than the above, such as TASK2 or a later one, can be calculated by adding (TASK number -1) to the Unit No. Example1: When reading the setting values of the average number of times (when ZS-LDC is 1CH, and no 2-area measurement is performed): Since the average number of times is 2Bh for Unit No. , and 02h for Data No. , values are shown as below: 02h 01h (C000h + 02h (Data No. )) 2Bh (Unit No. ) 01h (CH No. ) (8000h + 1h (Number of elements)) In the command section, the value is shown as below: 02h 01h C002h 2B01h 8001h To this command, if the response is shown as below: 02h 01h C002h 2B01h 8001h 00000004h Since the value is 4, this indicates 16 times. Example 2: When changing a high threshold value for the result of thickness to 100 mm (when ZS-LDC is 0CH, and a 2-area measurement is performed): The thickness result is calculated by using TASK3 when performing a 2-area measurement. Usually, the high threshold value is 30h for Unit No. , and 03h for Data No. Besides, 100mm thickness is expressed as 05F5E100h in a hexadecimal number because 100 mm is 100, 000, 000nm. 02h 02h (C000h + 03h (Data No. )) 58h (Unit No. ) 00h (CH No. ) and (8000h + 1h (Number of Elements)) 05F5E100h (Data to be written) In the command section, the value is shown as below: 02h 02h C003h 5800h 8001h 05F5E100h To this command, if the response is shown as below: 02h 02h 0000h It indicates a normal end.

For example, to change the current setting of the monitor focus, change parameters below: Monitor focus mode (ON) Monitor focus distance value 1 Monitor focus distance value 2 Monitor focus current value 1 Monitor focus current value 2 In addition, set outputs (current and voltage), which are set by the analog output switch in the controller. (Note 5) External input 0 mode and External input 1 mode settings cannot be changed because they automatically function as bank inputs when the bank mode is used (when "external input (IN) function mode" is set to "bank"). 3-10 When the external input mode is set to "STANDARD", the controller enters into the status below: * * * * External input of the controller is enabled, Commands from timing input to zero-resetting are disabled. External input of the controller is enabled, Commands from timing input to zero-resetting are disabled. When the external input mode is set to "Parallel input OFF", the controller enters into the status below: Therefore, to send a command related to inputs, the external input mode should be set to "Parallel input OFF. " Once ON is written to the timing input, reset input, and LD-OFF input parameters, the ON state is kept until OFF is written next. However, special care shall be taken because the operation changes depending on the state of external input line to the controller when the external input mode is set back to the "standard mode. " Operations are performed depending on the settings when "Execution" or "Cancel" is written to the parameter with respect to the zero-reset. Example 1: To perform zero-reset (when ZS-LDC is 1CH): The command sending sequence is as follows: (1) Write "parallel input OFF mode" to the "external input mode" parameter. (2) Write "execution" to the "zero-reset execution" parameter. (3) Write "STANDARD" to the "external input mode" parameter. An actual example of a command procedure is shown below: (1) 02h 02h C008h F001h 8001h 00000002h (2) 02h 02h C0C3h F001h 8001h 00000001h (3) 02h 02h C008h F001h 8001h 00000000h Writing commands (1) and (3) above before and after the input-related operation command, respectively, is recommended.

Therefore, flow data is immediately returned after sending a command when data accumulation has already been completed upon sending a command. Response is not performed unless the data accumulation is completed upon sending a command. Section 4 How to Obtain Flow Data 4-7 ZS Series CompoWay/F Communication Command Reference Section 4 Setting Parameters Setting Parameters This section describes buffer size, buffer interval, and logging data. Buffer Size and Buffer Interval Buffer size of the measurement data to be accumulated in the ZS controller and its buffer interval can be changed. To change buffer size and buffer interval, change the parameters below: * Use DATAGET and DATASET commands to change and view the parameter. Unit No. [. . . ]
