The Model 4101 ModBus Multivariable Transmitter integrates proven multivariable sensor technology with the implementation of industry-standard ModBus. Any ModBus master can access and control up to 32 Model 4101-MMTs that are multi-dropped on the RS-485 bus. The Model 4101-MMT is the ideal sensor for use with controllers in oil and natural gas flow measurement applications. Likewise, any DCS, PLC, RTU, or gas flow computer that can act as a ModBus master is compatible with the Model 4101-MMT.

The Model 4101-MMT measures process temperature, process pressure and differential pressure. By replacing three process transmitters with a single device, the Model 4101-MMT simplifies installation, reduces the likelihood of leaks, and significantly reduces installed cost. The Model 4101-MMT is more cost effective, more accurate and more rugged than competitive devices. The Model 4101-MMT is immune to atmospheric pressure variations and tolerates massive over-pressure without degradation of the sensor element or zero shift.

Typical applications of the Model 4101-MMT include natural gas flow measurement, and measurement of level, pressure and temperature within storage vessels and pipelines. The Model 4101-MMT's hazardous area certification makes it an ideal candidate for use in industrial, petrochemical and below-grade municipal applications

The Control Microsystems SCADAPackLP is one of five available models in the SCADAPack series of programmable logic controllers. The LP model is a low power controller complete with integrated power supply, analog and digital I/O, serial communications and turbine flow meter counter inputs. The product uses ModBus RTU, ModBus ASCII and DNP3 as native protocols and is remotely programmable, as a master or slave, through a choice of flexible programming languages. As with all SCADAPack products the SCADAPackLP is based on a multiprocessor architecture with a co-processor used for handling on-board input/output channels.

Features:

• Less than 400mW operating power required
• 3 counter inputs, including 2 turbine flow meter
• 6 analog inputs and 8 digital I/O points
• 2 RS-232, 1 RS-232/485 serial ports
• Optional integrated spread spectrum radio
• Class 1, Division 2 Hazardous Area Rating
• 3 year warranty on parts and labor

Overview:

Compact and Powerful - The Control Microsystems SCADAPackLP PLC provides Remote Terminal Unit (RTU) functionality with flexible programming options.

The unit is programmable in Relay Ladder Logic, IEC 61131-3 and multitasking C languages and provides an unlimited number of PID controllers for use in feedback control applications. The central processing unit includes a 16-bit CMOS microprocessor with 1 MB of CMOS RAM and 512 kB Flash ROM for use in firmware and application programming. Special

power saving features includes a Sleep Mode, 24V power shutdown and serial port power control. With 6 analog inputs, 8 digital I/O and 3 high-speed counter inputs, including two turbine meter inputs, the SCADAPackLP provides for a wide variety of process control and metering connections.

Flexible Communications - The SCADAPackLP provides two RS-232 and one RS-232/485 serial communication ports offering both ModBus RTU and ModBus ASCII communication protocols. For applications using an Ethernet LAN or WAN, a fully integrated Ethernet module is available. For those challenging remote applications a fully integrated, license-free spread spectrum wireless module is available at 900 MHz and 2.4 GHz. The SCADAPackLP also supports external radios and modems using Hayes AT commands, and can be programmed using powerful C tools for application specific protocols.

Applications:

With a special design focus on power efficiency the SCADAPackLP controller is a natural choice for applications that require low power along with a mix of analog and digital I/O and multiple communication ports. Coupled with real time communications using industry standard ModBus protocols, the SCADAPackLP integrates easily with a wide range of SCADA software, MMIs, DCS systems, intelligent instrumentation and remote I/O control applications. The SCADAPackLP is a flexible controller that can be used in both master and slave configurations. Special

features include report-by-exception and store and forward capabilities. With its mix of functions and features the SCADAPackLP is ideal for use in gas well optimization, plunger lift and oil field production applications. Using the optional Control Microsystems RealFLO software the unit is also ideal as a low power gas flow computer using AGA-3, 7 and V-Cone with AGA-8, NX-

19 calculations. In the water and wastewater sector the SCADAPackLP is well suited for use in dam control systems and environmental monitoring solutions.

In solar panel powered applications the SCADAPackLP offers further cost reduction by allowing smaller solar panels and batteries to be used. The integrated DC/DC converter and overall small footprint also enables the use of compact mounting enclosures for those applications

where space is at a premium. Similar in design to all other SCADAPack products, the

SCADAPack is fabricated with conformal coatings, gold plated machined sockets and zinc plated steel system components. Regardless of the specific need, the SCADAPack can provide reliable and compact standalone performance in the hazardous environments so often found in SCADA applications.
