"DATE_TIME_STAMP" timestamp DEFAULT NULL,ĬREATE OR REPLACE FUNCTION MODBUS_DATA_WRITE_BI_TRIGGER() The logger will use this column to read updates from the table.īelow you can find some table-creating scripts that we recommend to use. The "DATE_TIME_STAMP" column specifies the time when the value is changed last time. The table will contain one row for each register.
Add only one response item to each request with the "VALUE" name.Ĥ. For example, one request writes "int" values, another one "float" values.ģ.5. Note: You should add a separate request with a different event ID for each data type. You may use other identifiers but should change them in the next steps too. Then specify the event identifier like "WRITE-INT," "WRITE-FLOAT," "WRITE-UINT16". The plugin will receive it from a database.ģ.4. int64, double precision float - four registers (8 bytes).ģ.3.dword, int32, uint32, float - two registers (4 bytes).word, int16, unt16 - one MODBUS registers (2 bytes).16 (Write multiple registers) - if you need to write larger values (dword, uint32, int32, decimal32, float, etc.).For example, the value of the data type word, uint16, int16, decimal16. 6 (Write single register) - if you need to write a value that allocated one MODBUS register in the PLC memory.Click "Action - Add request" and add new requests to write data (fig. Select the "MODBUS TCP" or "MODBUS RTU" plugin from lists. Go to the "Modules - Query Parser Filter" page. If you've already configured the connection, then go to step #2.Ģ. If your device uses MODBUS RTU, look here. This example shows the connection settings for MODBUS TCP. You usually need to select the "TCP/IP" interface type for MODBUS TCP and "RS232" for MODBUS RTU. Create a new configuration from the main window using the "Green Plus" button. MODBUS RTU - baud rate and the number of data bits.ġ.
You must assign a static IP address for the device. MODBUS TCP - IP address, Subnet, Gateway.You have configured the communication settings on the device: This logger can work with MODBUS RTU and TCP at the same time.
