Bridge your Siemens S7‑200/SMART‑200 PLC’s serial port to Ethernet (S7‑TCP & Modbus‑TCP)—ideal for industrial control and SCADA systems.
Product Overview
The ETH‑200‑2P is an industrial‑grade Ethernet communication module designed for Siemens S7‑200 and SMART‑200 PLCs. As a “bridge” type Ethernet extension, it connects via RS‑232/RS‑485 serial (PPI/MPI/DP) without occupying the PLC’s programming port. It supports Siemens S7‑TCP and Modbus‑TCP protocols, allows up to 6 simultaneous clients, and supports auto‑adjusting baud rates up to 187 500 baud. Built‑in WEB‑server configuration and support for SCADA and touch‑screen master stations make it highly flexible in automation setups. Its power input includes anti‑reverse protection for reliable industrial use.
How to Use
- Mount the ETH‑200‑2P next to your S7‑200 PLC and connect to the serial expansion port (DB9 female) — PPI/MPI/DP cable, no programming port needed.
- Power it up (observe correct polarity; anti‑reverse protection in place).
- Access module’s WEB‑based setup by entering its default IP in a browser. Configure network (IP, gateway), baud rate, station number, and protocol (S7‑TCP or Modbus‑TCP).
- Connect your SCADA system or HMI panels over Ethernet (up to 6 masters supported).
- For reset, press and hold the Reset button for ~5 seconds; the SYS LED will stay on then reboot.
Frequently Asked Questions (FAQ)

User Review Summary
Few public reviews are available online. A known Amazon listing shows the module at approx. USD 263.86 but no customer ratings are displayed. No verified user feedback is evident; likely due to niche industrial use.
Comparison with Competing Products
ETH‑200‑2P vs Siemens CP‑243‑1 module:
- ETH‑200‑2P is third‑party, more affordable (≈USD 105–135 vs CP‑243 pricing), supports only S7‑200 series and Modbus‑TCP.
- Siemens CP‑243‑1 is official OEM, supports wider compatibility, seamless integration with Siemens software.
