SCADAPack 334E

SCADAPack™ Smart RTUs combine the communication and monitoring capabilities of an RTU with the processing and data-logging power of a PLC. They are ideal for remote processes that require automatic supervision and autonomous control. They are designed for the harsh conditions associated with remote sites in applications such as oil and gas and water and wastewater facilities.

**SCADAPack 334 E Series is obsolete and being replaced with SCADAPack 400 Series

SCADAPack™ 334 E is built on native DNP3 architecture and features high-performance 32-bit processing, high-speed LAN, USB and serial communications, advanced power management, integrated power supply and a wide range of analog and digital I/O. The level 4 compliant DNP3 protocol comes with optional Secure Authentication and/or AGA-12 Encryption to improve message security for critical operations and support for the open protocols of Modbus and IEC60870-5 is also offered. The SCADAPack 334 E can be programmed locally or remotely using the IEC61131-3 programming language and is optionally configurable directly from ClearSCADA host software. The compact design enables mounting in enclosures where space is at a premium.

SCADA: Learning the Basics

Supervisory Control and Data Acquisition (SCADA) systems are a combination of both hardware and software that allows monitoring of various devices that provide information about specific environments or processes. This information is transmitted through logic controllers, or other smart devices, and is sent to software interfaces known as an HMI, where the information is displayed in a way that individuals can read and interpret the data. SCADA is not only used for monitoring, it is also used for control. Through SCADA, it is possible to manipulate, move, or change the state of certain devices on the network. For example, it is possible to initiate a command through the HMI software that will energize or de-energize a solenoid valve, thus changing its state. In most scenarios, there are dozens, hundreds, or even thousands of points throughout a location or multiple locations that are being monitored and controlled through SCADA. SCADA systems can be found in many different industries such as telecommunications, water and wastewater, energy, oil and gas refining and transportation. These systems can be used to monitor and control only a few simple points, or can be used in massive energy plants where tens of thousands of data points are being interpreted and controlled every minute.

Hardware used in SCADA systems include:

PLCs, which can act as a bridge between the hardware and software, as well as providing data transmission and network communications.
Field monitoring and control devices, such as limit switches, temperature transmitters, pressure transmitters, solenoid valves, chemical monitoring devices and motor starters.

Software used in SCADA systems include:

HMI or Human Machine Interface software receives data throughout the system and organizes it in a way that can be easily interpreted. It can also provide control based on the information it receives.
