Description

The Siemens 6ES7341-1CH02-0AE0 (CP 341) is a specialized communication processor designed for the SIMATIC S7-300 PLC series. It provides a high-performance serial link for point-to-point communication, acting as a bridge between the S7-300 CPU and external peripheral devices such as printers, barcode readers, or third-party controllers. The module features an isolated RS422/485 (X.27) interface and supports standard protocols like ASCII and 3964(R), with the capability to support specialized protocols such as Modbus RTU via loadable drivers.

Features

• Isolated RS422/485 (X.27) interface for robust communication
• Supports loadable drivers for protocol flexibility (e.g., Modbus RTU)
• High-speed data transmission up to 115.2 kbit/s
• Integrated diagnostics for simplified troubleshooting
• Seamless integration into TIA Portal and SIMATIC Manager environments
• Galvanic isolation protects internal PLC circuitry from electrical interference

Applications

• Point-to-point serial data exchange in automation systems
• Integration of third-party devices into S7-300 architectures
• Data logging and reporting via serial printers or external terminals
• Barcode scanning and identification systems in manufacturing

Installation Guidelines

• Ensure the S7-300 CPU is powered down before inserting or removing the CP 341 module from the rack.
• Mount the module on the standard S7-300 DIN rail and secure it using the integrated locking mechanism.
• Use shielded twisted-pair cabling for RS422/485 connections to minimize EMI in industrial environments.
• Ensure proper grounding of the cable shield at the connector housing to prevent ground loops.
• Configure the module via the hardware configuration tool in STEP 7 or TIA Portal; ensure the correct driver is loaded for the intended protocol.
• Verify that the 24V DC power supply is stable and within the specified operating range.
