ODOT-PNM02

Product catalog summary

Product Description

Function: The ODOT-PNM02 is a protocol converter that enables data conversion between Modbus-RTU/ASCII and Profinet protocols, supporting devices with RS485/RS232/RS422 connectors.
Technical Parameters: It operates on 9-36VDC, supports Profinet I/O Device V2.3, with a data area of up to 1440 bytes for both input and output, and supports up to 50 slots and dual serial ports.

Hardware Description

Appearance: Includes two Profinet ports with switch functions for device access.
Indicators: Six LED indicators display power, device fault, system fault, network status, and data transmission status for serial ports.
Terminal Definition: A 10-pin terminal is used for RS485, RS232, and RS422 connections, with specific wiring definitions.
External Terminal Resistance: A 120Ω resistor is required for RS485 and RS422 modes to prevent signal reflection.

Using the Gateway in Siemens TIA V14

Configuration: Provides detailed steps for configuring the gateway in Siemens TIA V14, including network setup, GSD file installation, and module parameter configuration.
Module Parameters: Parameters are categorized into general, serial port 1, and serial port 2 settings, with options for baud rate, parity, stop bits, etc.
Diagnostic Modules: Optional modules for monitoring gateway and slave station status, including error codes for troubleshooting.

Error Codes and Troubleshooting:

Illegal Function Code (0x01): Unsupported function code by the slave station. Refer to the manual for the correct function code module.
Illegal Data Address (0x02): Data address is out of range. Modify the data starting address or length as per the manual.
Illegal Data Value (0x03): Data length exceeds the maximum allowable value. Adjust accordingly.
Slave Device Failure (0x04): Check the status of the slave device.
Slave Device Busy (0x06): Check the status of the slave device.
Parity Error (0x07): Verify parity, baud rate, stop bit, and hardware connection.
CRC Check Error (0x09): CRC calculation error in the slave response message. Check the working status of the slave station.
Unsolicited Slave Reply (0x0A): Increase timeout time and check hardware connection and communication parameters.
Slave Device Response Timeout (0x0B): Increase timeout time and verify hardware connection and communication parameters.
Response Message Length Error (0x0E): Increase the received character interval.
Write Slave Device Response Error (0x0F): Check hardware connection status.
Frame Format Error (0x31): Check communication parameters.
ASCII Length Error (0x32): Slave reply length error.
ASCII Value Error (0x33): Data contains non-hexadecimal ASCII codes.

Modbus Master and Slave Configuration:

Polling Time: Monitor the polling time of the serial port. Serial ports 1 and 2 are independent.
Module Control Output: Optional 8~48 channels. When enabled, the Module Control Output command is effective for reading and writing channels.
Modbus Function Codes Supported: 01/02/03/04/15/16 for both Master and Slave modes.
Read/Write Commands: Add commands to the hardware catalog and set module parameters such as serial port number, slave station ID, and data start address.
Hardware Configuration: Save and compile the project. Check for errors before downloading.
Modbus Slave Mode: Set gateway mode to Modbus Slave, configure serial port parameters, and add diagnostic modules if needed.
Device Name Modification: Use TIA software to update accessible devices and assign a new PROFINET device name for the gateway.
