PN1-S25 Module de raccordement de passerelle Profinet vers Modbus Prise en charge du protocole ProfiNet vers ModBus Configuration TIA Portal/STEP 7
[Interface de communication]：TTL
[Tension de fonctionnement]：3,3 V
[Dimensions]： 24 x 19 mm
[Poids]：3 ± 1 g
[Introduction]：Le module sans fil PN1-S25 est une passerelle Profinet vers Modbus RTU conçue pour la communication industrielle. Il permet de mapper les données Modbus vers Profinet. Il utilise des fichiers GSD pour l'intégration et peut lire et écrire des données sur les appareils Modbus sans code. Les données peuvent être rapidement configurées et transférées vers l'automate. Toutes les commandes Modbus sont chargées sous forme de modules. Le mappage mémoire entre Profinet et Modbus est intuitif et peut être interrogé via STEP 7 ou TIA Portal. L'octet d'état peut être chargé pour interroger l'état de connexion de l'appareil Modbus et le surveiller en temps réel. Il prend en charge le protocole Modbus RTU (maître/esclave).

| Serial number | Pin silk screen | describe |
| 1 | NC | Dangling |
| 2 | TXD2 | The serial port sends data, and the TTL level communication voltage only supports 3.3V |
| 3 | RXD2 | The serial port receives data, and the TTL level communication voltage only supports 3.3V |
| 4 | RXD2_LED | The output is flipped when serial port 2 receives data. The default output is high level. When receiving data, it outputs 25Hz square wave. |
| 5 | TX2_EN | Serial port 2 sends indication pin, which is set high when the serial port sends data and low normally; this pin can be used as RS485 chip enable control pin |
| 6 | TXD2_LED | The output of serial port 2 is flipped when there is data to send, the default output is high level, and the output is 25Hz square wave when receiving data |
| 7 | RXD1_LED | The output flips when serial port 1 receives data. The default output is high level. When receiving data, it outputs 25Hz square wave. |
| 8 | TXD1_LED | The output flips when serial port 1 has data to send, and the default output is high level. When receiving data, it outputs a 25Hz square wave |
| 9 | ERR_LED | (Modbus) Communication error indication, pull low: Modbus communication abnormal; set high: Modbus communication normal; when the configuration software controls the flashing indicator light, the level flips at the same time as SYS |
| 10 | SYS_LED | System (PN connection), pull low: PROFINET connection established, set high: PROFINET connection not established; when the configuration software controls the flashing indicator light, the level is flipped at the same time as ERR |
| 11 | NC | Dangling |
| 12 | GND | Common ground terminal, negative power input |
| 13 | GND | Common ground terminal, negative power input |
| 14 | VCC | Power positive input, supports 3.3V input |
| 15 | VCC | Power positive input, supports 3.3V input |
| 16 | NC | Dangling |
| 17 | NC | Dangling |
| 18 | NRST | By default, the internal pull-up is set to high, and the module will restart if the pull-down is set to low (about 100ms). |
| 19 | RELOAD | The factory reset pin has an internal weak pull-up and can be connected to an external reset button. A low level of about 5 to 10 seconds can restore the factory settings; a low level of 0.5 to 2 seconds can restart the module; pull low in the power-off state and then power on, and the device enters the upgrade mode; |

| 21 | LINK_LED | 10M PHY indicator light, pulled low after successful PHY negotiation, flashes when data is being sent or received; |
| 22 | SPD_LED | 100M PHY indicator light, pulled low after PHY negotiation is successful, flashes when data is being sent or received; |
| 23 | GND | Common ground terminal, negative power input |
| 24 | GND | Common ground terminal, negative power input |
| 25 | RX_N | Ethernet receiving RX-signal |
| 26 | RX_P | Ethernet receives RX+ signal |
| 27 | TX_N | Ethernet sends TX-signal |
| 28 | TX_P | Ethernet sends TX+ signal |
| 29 | NC | Dangling |
| 30 | WDI | Module working indication. This pin will continuously output square wave (1K-1MHZ) after the module is working normally. |
| 31 | TXD1 | The serial port sends data, and the TTL level communication voltage only supports 3.3V |
| 32 | RXD1 | The serial port receives data, and the TTL level communication voltage only supports 3.3V |
| 33 | NC | Dangling |
| 34 | TX1_EN | Serial port 1 sends indication pin, which is set high when the serial port sends data and low normally; this pin can be used as RS485 chip enable control pin |
