Set IOChannel

Set IOChannel Digital Input

Description Sets the Digital input settings for the channel.

User Level Admin

Syntax set iochannel <digital_channel>

[alarm [trigger disabledinactive-inputactive-input] [clear automanual] [email onoff] [syslog onoff] [snmp onoff]]

[description <string>] [invert-signal onoff]

[latch disabledinactive-to-activeactive-to-inactive]

Options digital_channel

Specify the Digital channel number, for example, d2.

alarm

Configures alarm settings when the Digital input trigger is activated.

trigger

When the trigger condition is met, triggers the specified alarm action. Triggers can be:

zDisabled—No alarm settings. This is the default.

zInactive—When the expected Digital input is active, going inactive will trigger an alarm.

zActive—When the expected Digital input is inactive, going active will trigger an alarm.

clear

Specify Manual to manually clear an alarm. Specify Auto to automatically clear the alarm when the trigger condition changes; for example, if the Trigger is Inactive and the alarm is triggered, once the input becomes active again, the alarm will be cleared when Auto is set. The default is Auto.

email

Sends an email alert to an email account(s) set up in the Server settings (the Line Email Alert settings are not used with this feature) when an alarm is triggered or cleared. The email alert data includes the severity level and the value that caused the alarm to trigger or clear. The Email Alert is associated with Level Critical.

syslog

Sends a message to syslog when an alarm is triggered or cleared. The syslog entry includes the severity level and the value that caused the alarm to trigger or clear. The syslog message is associated with Level Critical.

snmp

Sends an SNMP trap when an alarm is triggered or cleared. The trap consists of the severity level and whether the alarm was triggered or cleared.

description

Provide a description of the channel, making it easier to identify. The channel description can be up to 20 characters.

invert-signal

Inverts the actual condition of the I/O signal in the status; therefore, an inactive status will be displayed as active.

latch

Latches (remembers) the activity transition (active-to-inactive or inactive-to-active). The latched status is maintained until it is read. Once it is read, it will revert to the current status. The default is disabled.

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.
