Vlinx MESR9xx Modbus Gateway

Modbus ASCII

The Modbus ASCII message protocol is a human readable version of the Modbus message, and is one of the three Modbus formats supported by the MESR9xx Modbus Gateway.

A major advantage of Modbus ASCII is it allows up to a 1 second gap between bytes. It uses a Longitudinal Redundancy Check (LRC) checksum to verify message accuracy.

Modbus Message Buffering

The MESR9xx has two Modbus serial buffers, one for each serial port. Each will buffer up to 32 Modbus messages. These buffers help ensure messages don’t get lost in a data traffic jam, and are part of what makes Modbus such an outstandingly reliable serial protocol.

Modbus Message Timeout

Message timeout is supported by the MESR9xx. This is the maximum amount of time before a response to a message is expected.

Modbus RTU Message

The Modbus RTU message is broken into 4 different parts. The address field, the function code, this is copied directly over from the Modbus TCP message, the data and the error check, a 16 bit cyclic redundancy check or CRC.

Modbus Serial Control

Message Timeout

The message timeout is the maximum time the gateway allows for a response from the slave device. The default is 1000ms.
