MicroBrick Distributed I/O ModulesIntroductionMicroBricks are easy-to-use distributed I/O modules. They can be interconnected withScadaFlex or EtherLogic controllers for I/O expansion, connected to ProgrammableLogic Controllers (PLCs) or PC computers as rugged field I/O, or used with radios orleased-line modems to serve as low-cost Remote Terminal Units (RTUs).MicroBricks go beyond traditional “dumb” I/O modules by providing local intelligentsignal conditioning and data acquisition functions, as well as a local operator interfacethat can eliminate the need for laptop PCs, simulators or display terminals in the field.Modular I/O ExpansionMicroBricks provide a very modular means of adding I/O capacity as needed, withoutthe extra cost, wasted space and constraints of card racks. Need more I/O? Snap on amodule. Want to add some I/O a few hundred yards away? String a single twisted pairof wires and you’re up and running!Operator InterfaceAll MicroBricks come with a built-in alphanumeric operator interface and a simplified4-key keypad. This interface allows analog input and output levels to be displayed (likea panel meter), and allows both analog and discrete inputs and outputs to be forced(local override). The operator interface also supports I/O Module configurationfunctions such as network address, display brightness and power-saver timeout. TheLED display is bright enough for readability outdoors, and rated to withstand the widetemperature extremes that MicroBricks are designed for; -40ºC to 75ºC.Built-in NetworkingMicroBricks come network-ready with an isolated, dual-function (RS-485 and RS-232)serial communications interface. The RS-485 port can be used for low-cost 2-wirenetworking while RS-232 is a simple point-to-point interface to radios and modems aswell as PCs. MicroBricks support “store-and forward” messaging to extend the effectiverange of radio based systems by using the RTU as a digital repeater, withoutadditional radio hardware.Open ArchitectureMicroBricks use the Modbus RTU protocol, one of the most common protocols used incontrol systems. This protocol is supported by thousands of other hardware andsoftware products including all of the common PC-based MMI software packages frommanufacturers such as Wonderware, Intellusion, Iconics, and National Instruments.Peer-To-Peer CommunicationsFor true peer-to-peer operation MAXIO modules support ICL’s BrickNet protocol foruse with ICL EtherLogic and ScadaFlex Plus controller families. Protocol detectionbetween Modbus and BrickNet is automatic.10Copyright 2007 Industrial Control Links, Inc. All Right Reserved
MicroBrick Distributed I/O ModulesBack-To-Back I/O Bridge – Master ModeSome MicroBrick modules support a back-to-back I/O mirroring operation. This“Master mode” feature allows for the inputs on one module to be mirrored as outputson a remote module, and visa versa. This setup is designed to work with only a twounit network.Local I/O ProcessingMicroBricks perform local I/O processing to off-load time-sensitive operations from aHost system.MicroBricks with Discrete Inputs totalize input transitions and on-time (runtime) andcalculate pulse rates for every input. Applications include using digital pulse outputmeters for precise totalized flow and wattage calculations, as well as real-time flow rateand power usage information. Runtime is widely used for wear leveling betweenpumps or motors, and as the basis of an equipment preventive maintenance program.MicroBricks with Analog Inputs totalize the value of every Analog Input at a periodicsampling rate, especially useful for totalized flows and wattage applications usinganalog output type meters.MicroBricks with Discrete Outputs can be commanded to flash individual outputs at aprecise periodic rate independent of communications and I/O scan rates, primarily forvisual alarm annunciation.Wide Power Range and Low Power OperationMicroBricks are designed for use in solar and battery backed applications. Theyoperate over a wide range of DC power (10 to 30Vdc) and have built-in features tominimize their power usage. For example, the bright LED display used for the operatorinterface represents a significant portion of the modules power consumption. A userconfigurable power saver timer turns off the display when there has been no activity atthe keyboard for a while, but automatically turns on the display when any key ispressed.Rugged I/OAll I/O and communications interfaces are isolated and protected against overloads,transients, surges, and reverse polarity. Self resetting polymer fuses are usedthroughout. When the fault condition is corrected, the module automatically resumesnormal operation.Industry Leading WarrantyMicroBricks are backed by an industry leading 3-year factory warranty.Copyright 2007 Industrial Control Links, Inc.
