More Information

Overview Manuals Serial Drivers Frame Buffer RS422/485 Link Module Diagnostics

Features:

  • An isolated RS422/485 channel adds point-to-point communication to an S7-300 station.
  • A dedicated protocol processor handles serial framing separately from the CPU program.
  • Transmit, receive and system-fault LEDs distinguish data activity from diagnostic conditions.
Siemens 6ES7341-1CH01-0AE0 is a SIMATIC S7-300 CP 341 communication processor that links the PLC CPU with serial RS422 or RS485 equipment.

Protocol processing inside 6ES7341-1CH01-0AE0 controls serial framing and acknowledgment while program data moves between the communication processor and the S7-300 CPU.

Front indicators on 6ES7341-1CH01-0AE0 separate transmitted characters, received characters and module faults so communication activity can be distinguished from diagnostic events.

The Siemens 6ES7341-1CH01-0AE0 CP 341 RS422/485 Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Selecting the serial procedure

  • 3964(R) Link: The integrated procedure controls acknowledged serial transfer.
  • RK512 Link: The processor supports the documented computer-link procedure.
  • ASCII and Printer: Character-oriented and printer procedures are available for compatible devices.
  • Protocol Parameters: Framing, character timing and acknowledgment behavior are configured independently of the CPU program.

Moving serial frames to the CPU

  • Receive Storage: A 4096-byte buffer holds incoming serial frames for CPU access.
  • Input Transfer: Each program cycle moves up to 32 bytes from the processor to the S7-300 CPU.
  • Output Transfer: Each program cycle moves up to 32 bytes from the CPU to the processor.
  • Queue Selection: Buffer configuration retains one frame or as many as 250 frames.

Matching the RS422 or RS485 wiring

  • Connector: One isolated 15-pin Sub-D connector carries the serial signals.
  • RS422 Path: Separate transmit and receive pairs provide full-duplex communication.
  • RS485 Path: A shared pair provides half-duplex bus communication.
  • Cable Boundary: The selected bit rate and interface mode determine cable length and termination.

Distinguishing traffic from faults

  • Transmit Indicator: TXD follows characters sent through the serial interface.
  • Receive Indicator: RXD follows characters accepted from the connected device.
  • Fault Indicator: SF identifies parameter, interface or module diagnostic conditions.
  • CPU Reporting: A diagnostic interrupt passes the processor condition to the S7-300 CPU.
Description
Siemens 6ES7341-1CH01-0AE0 is an S7-300 CP 341 communication processor that gives the controller an isolated RS422/485 point-to-point interface for serial devices.

Protocol handling inside 6ES7341-1CH01-0AE0 separates serial framing from the CPU program. The processor can run 3964(R), RK512, ASCII or printer procedures, with loadable drivers available for additional supported protocols.

A 4096-byte receive buffer lets 6ES7341-1CH01-0AE0 hold complete serial frames while the S7-300 exchanges data with the module in blocks of up to 32 bytes per program cycle. Buffer settings determine whether one or multiple received frames remain queued for the CPU.

The 15-pin Sub-D interface on 6ES7341-1CH01-0AE0 carries either RS422 or RS485 signals, and cable length depends on the selected transmission rate. TXD, RXD and SF indicators separate traffic activity from module faults, while the external 24

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Should Siemens 6ES7341-1CH01-0AE0 be wired for RS422 or RS485?
Choose RS422 for a four-wire point-to-point link or RS485 for the documented two-wire half-duplex arrangement, then match the parameter assignment in Siemens 6ES7341-1CH01-0AE0.
Why can a long frame take several PLC cycles with Siemens 6ES7341-1CH01-0AE0?
Siemens 6ES7341-1CH01-0AE0 transfers up to 32 bytes in each direction per S7-300 program cycle, while its serial frame can be much longer.
What should be checked when the receive buffer on Siemens 6ES7341-1CH01-0AE0 fills?
Verify the CPU reads frames fast enough and confirm the configured buffered-frame count on Siemens 6ES7341-1CH01-0AE0 before increasing serial traffic.
Which protocol should be selected for a connected device on Siemens 6ES7341-1CH01-0AE0?
Use the procedure required by the serial device: Siemens 6ES7341-1CH01-0AE0 includes 3964(R), RK512, ASCII and printer procedures, with supported loadable drivers for other cases.
How are traffic and fault indications separated on Siemens 6ES7341-1CH01-0AE0?
TXD and RXD LEDs on Siemens 6ES7341-1CH01-0AE0 show transmitted and received characters, while SF identifies a module or parameter diagnostic condition.
