9.3 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 “EXP” can read or
write to several consecutive data locations, the maximum number
for each type of data is indicated in the column “Max number
bit/word read/written consecutively”.
