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 smaller 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. It's smaller size limits the I/O module quantity and restricts the radios to low-power VHF, UHF, and 800 MHz choices.
MOSCAD 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 by the Programming Toolbox, the created code compiled, and later downloaded into the CPU module.
The application resident within any local or remote MOSCAD unit may be monitored via the Programming Toolbox. When monitoring the local MOSCAD unit, the Toolbox plugs into an available RS-232 port on that CPU module. When monitoring a remote MOSCAD unit, the Toolbox connects to an RS-232 port on any local MOSCAD unit and utilizes the communication network to access the desired remote MOSCAD unit. When operating over an Ethernet (INTRANET) LAN, the Toolbox may connect directly to the LAN and communicate with the remote MOSCAD units at 10baseT data speeds. New application codes may be downloaded to the MOSCAD CPU; current or historical data may be uploaded from the CPU; the contents of the CPU's error logger may be retrieved.
