FAQ

Q：What Modbus Communication modes and physical interfaces does the ODOT-PNM02 V2.1 support?

A：The gateway supports both Modbus RTU and ASCII protocols and can be configured as either a Modbus master or slave. It features two serial ports that can be flexibly configured as dual RS485/RS232 or a single RS422 interface, accommodating diverse field device connectivity requirements.

Q：How many Modbus devices can this gateway connect to on the PROFINET side, and what is its data throughput capacity?

A：It can manage up to 60 Modbus slave devices with support for 200 read/write commands. On the PROFINET side, it offers up to 1440 bytes of input and 1440 bytes of output data area, with up to 50 configurable slots in TIA Portal for efficient data mapping and exchange.

Q：Is this gateway suitable for harsh industrial environments, and does it support quick recovery?

A：Yes, it operates reliably in extreme conditions with a wide temperature range of -40°C to +85°C. It also features a “one-key reset” function for rapid restoration to factory defaults, significantly simplifying on-site commissioning and maintenance.
