range

Specify the temperature range that you want to measure. For RTD, the range is:

z1 (Pt100 a=385 -50 to 150C) This is the default.

z2 (Pt100 a=385 0 to 100C)

z3 (Pt100 a=385 0 to 200C)

z4 (Pt100 a=385 0 to 400C)

z5 (Pt100 a=385 -200 to 200C)

z6 (Pt100 a=392 -50 to 150C)

z7 (Pt100 a=392 0 to 100C)

z8 (Pt100 a=392 0 to 200C)

z9 (Pt100 a=392 0 to 400C)

z10 (Pt100 a=392 -200 to 200C)

z11 (Pt1000 a=385 -40 to 160C)

z12 (NiFe604 a=518 -80 to 100C)

z13 (NiFe604 a=518 0 to 100C)

For thermocouple, the range is:

zb (B 500 to 1800C)

ze (E 0 to 1000C)

zj (J 0 to 760C) This is the default.

zk (K 0 to 1370C)

zr (R 500 to 1750C)

zs (S 500 to 1750C)

zt (T -100 to 400C).

alarm

Configures alarm settings when the Analog input trigger is activated.

level

You can specify up to five alarm trigger/clear severity levels. If the Trigger Type is Low, an alarm is triggered when the input drops below the specified Trigger value; other severity level trigger values must decrease in value with each subsequent level. If the Trigger Type is High, an alarm is triggered when the input is higher than the specified Trigger value; other severity level trigger values must increase in value with each subsequent level. To clear an alarm, the input must drop below the specified value when Trigger Type is High or go above the specified value when Trigger Type is Low.

mode

Enables/disables an alarm level. The default is off.

trigger-type

If the Trigger Type is Low, an alarm is triggered when the input drops below the specified Trigger value; other severity level trigger values must decrease in value with each subsequent level. If the Trigger Type is High, an alarm is triggered when the input is higher than the specified Trigger value; other severity level trigger values must increase in value with each subsequent level.

trigger-level

Specify the value that will trigger an alarm, the measurement is based on the Type and Range that you specify. This value must not fall within the scope of the value used to clear an alarm.

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.
