6.3 Protocol NAIS Matsushita Master
This is the protocol that permits the reading and writing of data (bit
of word) of the PLC Nais Matsushita.
Generally, the communications interface is RS232, the velocity is
9600 baud (bits/sec), the format of communications 8,O,1 (8 bits
of data, odd parity, 1 stop bit).
The following table indicates all of the elements that can be
read/written from the PLC. The address of the bit o of the word to
read or write is obtained by adding the real address of the bit/word
(between Min and Max) to the value indicated in the column
Offset. Each instruction “COM” or “EXP” can read or write to
several consecutive data locations, the maximum number for each
