The IE-GW-MB-2TX-1RS232/485 serves as a direct upgrade path for older serial-to-Ethernet converters. It is fully compatible with standard Modbus TCP client drivers found in modern PLC platforms (such as Siemens S7, Rockwell ControlLogix, and Schneider Modicon) without requiring custom driver blocks.
When configuring RS-485 2-wire communication, ensure that the appropriate termination resistors (typically 120 ohms) are installed at both physical ends of the serial bus. Failure to terminate the line can result in signal reflection, leading to intermittent CRC errors and communication timeouts, especially at baud rates exceeding 19200 bps.
Initial setup is performed via the integrated web-based management interface. Ensure your commissioning PC is configured on the same subnet as the gateway's default factory IP address. Always ground the functional earth pin (Pin 3) to the central cabinet ground plane to safeguard the internal transceiver components against transient voltage spikes.
CRITICAL WARNING
Isolate all power sources before mounting, wiring, or servicing the gateway. Do not insert or remove the 7-pole terminal block while the circuits are energized to prevent electrical arcing and potential damage to the internal electronics.
Snap the gateway securely onto a standard TS 35 DIN rail, ensuring the metal grounding spring on the rear makes firm contact with the rail.
Connect the serial communication lines (RS-232 or RS-485) to the designated serial port interface using shielded cabling.
Wire the redundant 24 V DC power supplies to the 7-pole terminal block, ensuring correct polarity before plugging the connector into the unit.
Connect the RJ45 Ethernet cables to the 2TX ports to integrate the gateway into your local industrial Ethernet network.
