MOSCAD (MOtorola SCADa) is the Motorola product specifically designed to the requirements of Fixed Data systems. At the core of MOSCAD is the 68000-based CPU module, complete with RAM, ROM, real-time clock, RS-232 and RS-485 data ports, and a communication port. Plug-in specialized I/O modules provide the connectivity to digital (binary) and analog (value) sensors, and provide relay (to control devices) and analog (to change process setpoint) outputs. Modularity permits the MOSCAD configuration at every site to be optimized to the specific requirements of the site. Connectivity via the RS-232 and RS-485 ports to devices capable of serial data communication is also available.

		MOSCAD-L is the mid-sized and less-costly member of the overall MOSCAD family. MOSCAD-L retains the RS-232, RS-485, etc. capabilities of MOSCAD and provides the I/O capabilities most commonly used. Its smaller size limits the I/O module quantity and restricts the radios to low-power VHF, UHF, and 800 MHz choices.

MOSCAD is available in the large NEMA-4 enclosure shown in the picture, in a NEMA-4 enclosure that is half the size and accommodates half as many I/O modules, or on 19" rackmount panels. The rackmount configuration may be expanded to accommodate up to 67 I/O modules. Stainless steel and plastic enclosures are also available. MOSCAD-L is available in a fiberglass-reinforced lexan enclosure that accommodates 3 plug-in I/O modules. A steel NEMA-4 enclosure is also available.

MOSCAD commonly uses two-way radio for the communication channel. Models with high and low power VHF, UHF, and 800 MHz radios are available.

The MOSCAD RTU provides the features of both a Remote Terminal Unit (RTU) and a Programmable Logic Controller (PLC). If the application program loaded into the CPU module is simple, then MOSCAD functions as an RTU; if the application program implements decision-making code, then MOSCAD functions as a PLC. Either type of application program is created using the MOSCAD Programming Toolbox and/or the MOSCAD "C" ToolKit. The created code is compiled and downloaded into the CPU module.

The application resident within any local or remote MOSCAD RTU may be monitored via the Programming Toolbox. When monitoring a local unit, the Toolbox plugs into an available RS-232 port on that CPU module. When monitoring a remote unit, the Toolbox connects to an RS-232 port on any local unit and utilizes the communication network to access the desired remote unit. New or revised application codes may be downloaded to the local or remote MOSCAD CPU; current or historical data may be uploaded from the CPU; the contents of the CPU's error logger may be retrieved.
