This section describes the steps to setup required and optional database tables for CNCnetPDM in case you're using a MySQL or MariaDB (Version >= 5.5!) database.
Note: Starting with CNCnetPDM Ver. 6.3.3.1 the names of all database tables can be configured on a per-service basis, see chapter Connect of CNCnetPDM INI file for details.
For a MySQL or MariaDB database the information in section SQL Server Database tables applies also but the scripts to create the tables look slightly different.
The following code can be used to create MTH_RAW_DATA. CNCnetPDM stores all data acquired in every reading cycle in this table. This Alternatively you can use MTH_RAW_DATA_MYSQL.sql from this zip archive. Here database MDA is used, please change that according to your needs.
USE MDA; -- Here database MDA is used
CREATE TABLE MTH_RAW_DATA (GROUP_ID BIGINT, READING_TIME DATETIME NOT NULL, DEVICE_NUMBER INT NOT NULL, TAG_CODE VARCHAR(255) NOT NULL, TAG_DATA VARCHAR(255), CREATION_DATE DATETIME, PROCESSING_FLAG INT DEFAULT 2 NOT NULL); -- Setup table to store all records
FIG 1: Setup script (MySQL or MariaDB) for database table MTH_RAW_DATA
MTH_ONLINE_DATA
To only store the most recent data from your machines you can use table MTH_ONLINE_DATA. CNCnetPDM updates all existing records for every device in this table when new data is queried. The update interval depends on the value for PollInterval in section [GENERAL] of CNCnetPDM.ini. To use this table please make sure that you have set WriteOnlineData = 1 in section [Connect] of CNCnetPDM.ini. You can create table MTH_ONLINE_DATA manually by using the following code or file MTH_ONLINE_DATA_MYSQL.sql from this zip archive. Here again database MDA is used, please change that if needed.
USE MDA; -- Here database MDA is used
CREATE TABLE MTH_ONLINE_DATA (GROUP_ID BIGINT, READING_TIME DATETIME NOT NULL, DEVICE_NUMBER INT NOT NULL, TAG_CODE VARCHAR(255) NOT NULL, TAG_DATA VARCHAR(255), CREATION_DATE DATETIME, PROCESSING_FLAG INT DEFAULT 2 NOT NULL); -- Setup table for device monitoring
FIG 2: Setup script (MySQL or MariaDB) for database table MTH_ONLINE_DATA
MTH_USER_CONTEXT
For table MTH_USER_CONTEXT you can use the following code or alternatively MTH_USER_CONTEXT_MYSQL.sql from this zip archive. Here again database MDA is used, please change that if needed.
USE MDA; -- Here database MDA is used
CREATE TABLE MTH_USER_CONTEXT (USER_CONTEXT_PK_KEY INT NOT NULL, SCAN_TIME VARCHAR(255) NOT NULL, EQUIPMENT_FK VARCHAR(255) NOT NULL, WORKORDER_FK VARCHAR(255) NOT NULL, SEGMENT_FK VARCHAR(255) NOT NULL, ITEM_FK VARCHAR(255) NOT NULL, CONSTRAINT MTH_USER_CONTEXT_PK PRIMARY KEY (USER_CONTEXT_PK_KEY)); -- Setup table for workorders, segments and parts
FIG 3: Setup script (MySQL or MariaDB) for database table MTH_USER_CONTEXT
MTH_EQP_SHIFT_AVAIL_V
To only acquire data within an active shift for a device you can use the following code or alternatively file MTH_EQP_SHIFT_AVAIL_V_MYSQL.SQL from this zip archive.
USE MDA; -- Here database MDA is used
CREATE TABLE MTH_EQP_SHIFT_AVAIL_V (EQUIPMENT_FK VARCHAR(255) NOT NULL); -- Setup table to determine if there is an active shift
FIG 4: Setup script (MySQL or MariaDB) for database table MTH_EQP_SHIFT_AVAIL_V
For testing you can insert the 4 digit device number into field EQUIPMENT_FK and adjust the .ini file for CNCnetPDM to only collect data within a shift. In a production environment MTH_EQP_SHIFT_AVAIL_V should be a view that looks up if there’s an active shift for the equipment in a shift table and, if yes, returns the 4 digit device number.
