Set Line

Set IO Failsafe

Description

Sets the failsafe (watchdog) settings for I/O.

User Level

Admin

Syntax

set io failsafe [mode onoff] [timeout <seconds>]

Options

mode

 

Enables/disables the Failsafe Timer. This is the global setting that must be enabled to

 

set the Failsafe Action on the channel for digital outputs and relays. When this timer

 

expires because of no I/O activity within the specified time interval, the Failsafe Action

 

set for the channel determines the action on the output.

 

timeout

 

The number of seconds that must elapse with no I/O activity before the channel

 

Failsafe Action is triggered. Valid values are 1-9999. The default is 30 seconds.

Set IO Modbus

Description

Enabling the Modbus option makes the IOLAN act as a Modbus Slave, allowing

User Level

Modbus Masters to communicate with the IOLAN to control and/or retrieve I/O data.

Admin

Syntax

set io modbus [mode onoff] [uid <1-255>]

Options

mode

 

Enables/disables Modbus as the communication protocol for all the I/O channels.

 

uid

 

This is the UID you are assigning to the IOLAN, which is acting as a Modbus slave.

Set IO Temperature-Scale

Description

Sets the temperature scale that will be used for all I/O temperature readings.

User Level

Admin

Syntax

set io temperature-scale celsiusfahrenheit

Option

temperature-scale

 

Select the temperature scale that will be used to display temperature data, either

 

Fahrenheit or Celsius. The default is Celsius.

Set Line

Set Line Service

Description Sets the Line Service settings for signal I/O. When the line service is set to signal-io, you also have the option of enabling the I/O extension for the serial singal pins. See Set IOChannel IOExtension on page 152 for more information.

User Level Admin

Syntax set line <number> service signal-io

Option signal-io

Sets the line to use signal I/O. You still need to define the serial pins for digital input (CTS, DSR, or DCD) or digital output (RTS or DTR). See Set IOChannel Digital Input (Serial Pins) on page 145 or Set IOChannel Digital Output (Serial Pins) on page 147 for configuration options.

SDS, MDC specifications

Perle Systems is a leading provider of connectivity solutions, renowned for its robustness and reliability in networking hardware. Among its expansive product offerings, the MDC (Multiport Device Converter) and SDS (Serial Device Server) stand out as pivotal solutions for industries requiring seamless data communication and device management.

The Perle MDC serves as a powerful multi-port device converter, providing the ability to connect multiple serial devices to a computer network without needing a separate connection for each device. This is particularly useful in environments with limited computing resources or high device density, such as railways, manufacturing plants, or remote field operations. It is designed to convert serial communication, which is commonly used in legacy devices, into Ethernet/IP or TCP/IP protocols, ensuring that older devices can integrate into modern networks.

Main features of the MDC include its robust design for industrial environments, support for a variety of serial protocols, and multiple device connections. It supports data rates of up to 115200 bps and provides easy monitoring and configuration via a web-based interface. Additionally, the MDC incorporates advanced security features including SSL and SSH encryption, ensuring data integrity and protection against unauthorized access.

On the other hand, the Perle SDS model exemplifies advanced serial device hosting capabilities, allowing users to connect Ethernet networks to serial devices. It acts as a bridge, enabling remote devices to be configured and managed over IP networks. The SDS series is known for its versatility, supporting a range of serial communication protocols, including RS-232, RS-422, and RS-485, making it suitable for various applications such as point-of-sale systems, industrial automation, and remote monitoring.

The SDS boasts several characteristics that enhance its functionality, such as automatic device discovery, real-time monitoring, and local or cloud-based management options. Its feature set also includes traffic management capabilities, allowing the optimization of device communication by controlling the flow of data, which is critical for applications requiring high reliability and low latency.

Both the MDC and SDS benefit from a strong emphasis on ease of deployment and management. They support a range of network topologies, facilitating seamless integration into existing infrastructures. Furthermore, these devices are backed by Perle Systems' reputation for customer support and a commitment to ongoing innovation, ensuring that organizations can rely on these solutions for future growth and technological advancement.
