3.2.17. WRITING THE DATE AND TIME OR RESET THE ENABLED TOTALIZERS
Codice comando: 03
Formato comando: ADDRESS TO
+ ADDRESS FROM
+ 03H
+ 04H
+ 32 bits long integer containing the date and time expressed in minutes starting from 01-01-
1992, or the value FFFFFFFFH to reset the totalizers
the most significant byte must be sent first.
+ CRC CHECKSUM
Reply data format: the same block is returned containing the current clock value in minutes. If the value sent is
outside the limits, (date beyond 31-12-2091), the clock restarts from 01-01-1992. In case
of totalizers reset, the same value FFFFFFFFH is returned.
3.2.18. SEND / RECEVE BATCH PROCESS DATA ML210 /ML 3F1
The batch data can be read or written with the command described below. Th command contains an OPCODE byte
specifying the operation type to be done on the selected batch data. With these commands one of the 16 batch
memories can be written, read or it can be set as active batch process. Once set a selected batch memory, it will be
possible start, stop or reset the batch process. To set a batch memory as active batch process, a write or read
command can be used indifferently, but the bit 6 of the OPCODE must be set to 1
– Command for reading a batch data memory:
Command code: 08
Command format: ADDRESS TO
+ ADDRESS FROM
+ 08H
+ 01H (1 DECIMALE)
+ OPCODE byte, operation code:
bits 0..4 = number of the batch memory to be read (0..15)
bit 5 = must be set to zero
bit 6 = 1 if this batch memory must be set as active batch process, 0 if this batch
memory is to be read only.
bit 7 = must be set to zero
+ CRC CHECKSUM
Format of the returned data: 16 bytes containing the batch data for the selected memory:
bytes 0-7: (8 bytes ASCII) memory batch 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 safety batch 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.
