– Comando per scrivere i dati su una memoria di dosaggio:
Command code: 08
Command format: ADDRESS TO
+ ADDRESS FROM
+ 08H
+ 11H (17 DECIMAL)
+ OPCODE byte, operation code:
bits 0..4 = number of the batch memory to be written (0..15)
bit 5 = must be set to one
bit 6 = 1 if this batch memory must be set as active batch process, 0 if this batch
memory is to be written only.
bit 7 = must be set to zero
+ 16 bytes of data to be written on the batch memory:
bytes 0-7: (8 bytes ASCII) batch memory name (allowed characters: 0..9, a..z, A..Z, space
(32 DEC, 20 HEX))
bytes 8-9: (2 bytes 16 bit unsigned integer, MSB first) number of batch processes done for
this batch memory.
bytes 10-11: (2 bytes 16 bit unsigned integer, MSB first) value of the batch safety timer
expressed in tenths of seconds.
bytes 12-15: (4 bytes 32 bits unsigned long integer, MSB first) batch quantity value
expressed in the same units and with the same decimal digits of the volume
counters.
+ CRC CHECKSUM
Format of the returned data: 16 bytes containing the same batch data for the selected memory sent (if there were any
characters or values not allowed, they are corrected to the right values). The data format are the same of the
precedent function.
c) - Command for reading the current batch process state:
Command code: 08
Command format: ADDRESS TO
+ ADDRESS FROM
+ 08H
+ 01H (1 DECIMAL)
+ OPCODE byte = 80H (128 DECIMAL)
+ CRC CHECKSUM
Format of the returned data: 1 byte containing the batch process state:
0 = batch process is correctly terminated (pre-set quantity reached).
1 = batch process is running (the valve is opened and the counters are running).
2 = batch process is suspended (the valve is closed before the pre-set quantity is reached).
d) - Command for starting or suspending the current batch process:
Command code: 08
Command format: ADDRESS TO
+ ADDRESS FROM
+ 08H
+ 01H (1 DECIMAL)
+ OPCODE byte = 81H (129 DECIMAL)
+ CRC CHECKSUM
Format of the returned data: 1 byte containing the batch process state as described above.
