CPU_PROD_ENTRY_READ¶
The Function Block reads one line from the production data in the Flash memory. One line consists of a pair of key values and is located within a section.
The section name of the production data is called “Common”. It consists of many keys with the corresponding values, see table:
| Production data | Comment | |
|---|---|---|
| Common | Section Name | Name of the section |
| BA_INST | Key and value | BA number |
| IDENT | Key and value | SAP identnumber |
| INDEX | Key and value | Index of the module |
| MAC | Key and value | MAC address of the CPU |
| MANUF_DATE | Key and value | Manufacturing date |
| MANUF_YEAR | Key and value | Manufacturing year |
| MANUF_PLACE | Key and value | Place where the PLC was produced |
| SERIAL_NR | Key and value | Serial number of the PLC |
| TYPE | Key and value | CPU type |
The procedure should be performed in three steps:
Initialization (ACT = FLASH_DATA_INIT) of the production data with a FALSE/TRUE edge at input EN.
Reading (ACT = FLASH_DATA_READ) of the individual values (SECTION, KEY_SEARCH, INDEX) with a FALSE/TRUE edge at input EN.
Cancel (ACT = FLASH_DATA_SKIP) the reading with a FALSE/TRUE edge at input EN.
