Set IOChannel

enabled

When enabled, the digital input channel or DSR/DCD/CTS input serial signal pins can be connected to:

zA Digital output or relay (if the I/O model supports relay) channel on the same

IOLAN

zOutput Serial Signal Pins (DTR/RTS)

zA Digital output channel on another IOLAN(s) or output serial signal pins (DTR/RTS) on another IOLAN(s)

zA TCP/IP application(s) running on a host on the network

When enabled, the digital output/relay channel or DTR/RTS output serial signal pins can be associated with a digital input channel or input serial signal pins.

Default: Disabled keepalive

Enables a per-connection TCP keepalive feature. After the configured number of seconds, the connection will send a gratuitous ACK to the network peer, thus either ensuring the connection stays active OR causing a dropped connection condition to be recognized.

This parameter needs to be used in conjunction with server parameter, monitor-connection-every. The interval determines how long the IOLAN will wait during inactivity before "testing" the connection. It should be noted that if a network connection is accidentally dropped, it can take as long as the specified interval before anyone can reconnect to the serial port.

connection-method

The connection-method is one of the following:

zClient-Initiated—When specified, the channel/serial signal pin will wait for connections to be initiated by another I/O channel or a TCP/IP application.

zServer-Initiated—When specified, the channel/serial signal pin initiates communication to another I/O channel or a TCP/IP application.

zLocal-Connection—When specified, the input or output, depending on how the channel or serial signal pin is configured, will be associated with another local IOLAN I/O channel or serial signal pin.

When the channel is configured as digital input or when configuring an input serial signal pin, the Output Channels parameter displays all the local digital output signals or relays that it is associated with.

When the channel is configured as digital output, you must select a local digital input channel or input serial signal pin on the IOLAN.

Note that the Failsafe Action is not compatible with the local-connection option. Default: Client-Initiated

client-initiated tcp-port

The TCP port that the channel/serial signal pin will use to listen for incoming connections.

Default: 2000 for channel 1, then increments by one for each channel

client-initiated multihost

When this option is enabled, multiple I/O channels and/or TCP/IP applications can connect to this channel/serial signal pin. The default is off.

CSS specifications

Perle Systems, a well-established provider of networking and IoT solutions, offers the innovative Perle CSS (ClearSky Services) platform, designed to facilitate efficient and secure device management. This powerful solution aims to address the challenges of managing a diverse range of devices connected to the Internet, particularly in enterprise, industrial, and M2M (Machine-to-Machine) environments.

One of the main features of the Perle CSS is its robust device management capabilities. Administrators can remotely monitor, configure, and control devices in real-time. This means that troubleshooting can be conducted without the need for physical access, significantly reducing operational downtime. Additionally, the platform supports bulk provisioning, allowing organizations to onboard multiple devices simultaneously, which streamlines the deployment process.

Another notable feature is its security architecture. Perle Systems has integrated advanced security protocols to ensure the integrity and confidentiality of data transmitted between devices. The use of virtual private networks (VPNs), secure socket layer (SSL) encryption, and secure shell (SSH) protocols ensures that sensitive information remains protected from unauthorized access while in transit.

The Perle CSS also stands out for its compatibility with various communication protocols, including MQTT, RESTful APIs, and others. This interoperability allows organizations to integrate the CSS platform seamlessly with their existing systems, facilitating efficient data exchange and interoperability between different devices and applications.

Moreover, Perle CSS adopts a cloud-based architecture, which provides users with the flexibility to access device information from any location. This cloud integration enhances scalability, allowing businesses to expand their network capabilities without the need for extensive infrastructure investments.

The platform's user-friendly interface simplifies navigation, allowing users to manage devices effectively without requiring extensive technical expertise. With customizable dashboards and real-time analytics, administrators can gain valuable insights into device performance, network status, and usage patterns.

In summary, Perle Systems' CSS offers a comprehensive solution for managing connected devices in a secure and efficient manner. Its key features, including robust device management, advanced security, protocol compatibility, and a cloud-based architecture make it an ideal choice for enterprises looking to enhance their IoT capabilities and streamline operations in an increasingly connected world.
