Real-time monitor (NEC)
Interpreter-type multitasking BASIC and machine language (V25)
16 (can be executed in parallel)
Message transfer by SEND and RECEIVE instructions. Data sharing by global variable
Notification of event occurrence by SENDSIG, ON SIGNAL GUSOB, and TWAIT instructions
Started by TASK instruction, and stopped by END, STOP, or EXIT instruction
Tracing by TRON instruction, one-instruction execution by STEP instruction, pause and
resumption by STOP, BREAK, and CONT instructions
RAM Source code area: 63K bytes
Variable area + executable code area: Approx. 110K bytes
32K bytes of variable area reserved for non-volatile variables.
EEPROM To save source program: 63K bytes (BSC21, 41, and 61 only)
The number of times the program can be written to the EEPROM is limited
to 5,000. Do not exceed this limit.
Cyclic Total of 384 I/O words possible
Default: 10 input words and 15 output words (via CPU Unit's I/O refresh)
CPU bus Default: No CPU bus link. To link CPU bus, CPU bus link must be set with
link the CVSS.
Number of words read from CPU Unit: 128 max.
Number of words read between CPU Bus Units: 8 max
(The CPU Bus Link Area is refreshed by CPU Unit at 10-ms intervals.)
Event When PC READ or PC WRITE instruction is executed:
512 bytes max. each for read and write

When the memory is backed up with no power applied, the life expectancy depends on the
ambient temperature. When the BAT LOW indicator on the front panel of the Unit is lit,
replace the old battery with a new one within 1 week.
