The MOSCAD-L CPU module is the brain of the MOSCAD-L product line. It has a Motorola 68LC302 16/32-bit CMOS processor, RAM and Flash memory, plus the interfaces to the I/O and communication aspects of the RTU; time functions are supported by a software clock in the operating system. The CPU module plugs into the module rack immediately adjacent to the power supply module. The CPU module may be programmed by ladder-logic, using the MOSCAD-L Programming ToolBox, to provide it with the capabilities expected of a PLC. Compiled functions written in “C” may be downloaded into the CPU module. Each CPU module contains three data ports with different capabilities. Port 1 provides either RS-485 (2-wire multidrop) or async RS-232 (data but no RTS, CTS, DTR, etc.) communications to the Programming ToolBox or sync RS-232 communications to CPU modules in other MOSCAD or MOSCAD-L RTUs. Port 2 provides async RS-232 communications and may be configured as either DTE or DCE for data connectivity under the control of the loaded application or configured as a system port for local ToolBox use. Port 3 is normally the communication port and contains a plug-in communication interface appropriate to the medium used. The port may also be provided with a full RS-232 plug-in when required. The CPU module includes 20 LEDs that provide information regarding the operation of the CPU and I/O modules. The LEDs indicate the availability of a configuration and application in Flash memory, communication status via the ports, state of I/O module connections, etc. Availability: Usually ships in 6-8 weeks.
