All symbols of an AS can be seen in Symbols (Caldeira_Prj > AS_CALD > CPU 416-3 PN/DP > CALD > Symbols).
The Symbols table can be exported (Symbol Table > Export...) menu and new symbols can be imported (menu Symbol Table > Import...).
Example of an ASCII file with I/O symbols for import.
• Insert IE-PB Link 6GK1 411-5AB00 in PN_Caldeira_Campo subnet (catalog - Profile Standard > PROFINET IO\Gateway\IE/PB Link PN IO\6GK7 411-5AB00). Click on item 2.1 and drag to the PN_Caldeira_Campo subnet.
• Create the Profibus_Caldeira_Campo subnet. In the Network Settings tab, set the speed of the Profibus (Transmission Rate) subnet to 45.45 (31.25) Kbps.
• Insert Profibus-PA instruments in the Profibus_Caldeira_Campo subnet. Profibus-PA instruments of 3 types will be inserted:
1 – LD303 – Smar Pressure Transmitter; GSD: SMAR0895.GSD
2 – FY303 – Smar Positioner;
3 – TT303 – Smar Temperature Transmitter;
Instruments:
| Tag | Description | Type | Address | Input | Output |
|---|---|---|---|---|---|
| LT200 | Boiler Level | LD303 | 5 | I4...8 | |
| FT200 | Feed Water Flow | LD303 | 6 | I9...13 | |

• Select LD303 in the catalog and drag it to the Profibus_Caldeira_Campo subnet. Set the address to 5. Create the Profibus_Caldeira_Campo subnet with 45.45 (31.25) Kbps speed. Link the Profibus-PA slave to the Profibus_Caldeira_Campo subnet.
• Insert Analog Input module (short) in slot 1 of the instrument. Change input address to I4 ... 8.
• Insert EMPTY_MODULE module in slot 2 of the instrument.
• Repeat the above procedure for all pressure and temperature transmitters in the list.
• Select FY303 in the catalog and drag it to the Profibus_Caldeira_Campo subnet. Set the address to 7. Link the Profibus-PA slave to the Profibus_Caldeira_Campo subnet.
• Insert eSP + RB + POS_D + CB module in slot 1 of the instrument. Change input address to I14...28 and output address to Q14...18.
