101 (hex0065) = Scale 1, Block 101 Write “Batch” data of Scale 1,
#2 –FIRST REGISTER NUMBER
Registers in the groups are numbered from 0 to n, and the master has the
possibility to write only a portion of the registers composing the group.
This parameter specifies the first register to write; 0 means the first
register of the group.
#3 –NUMBER OF REGISTERS
This parameter specifies the number of register to write.
#4 –STAMP
In the PROFIBUS protocol, data is transmitted continuously, so the same
telegram is sent by the master to the slave several times. To avoid the
slave interpreting the same data continuously (it would create problems;
for example, with the commands), the element called “stamp” is used.
The slave interprets received data only if the stamp is different from the
stamp received in the previous telegram. The master has only to change
the stamp value when it creates a new telegram. The stamp of the last
interpreted telegram is re-transmitted by the Micro-Tech in the read
buffer.
The Data section contains the data to write in the order MSB – LSB (Most
Significant Bit – Least Significant Bit).
When the Micro-Tech processes the package, before writing the received
data in the registers, it checks that all the parameters are correct (example:
Block identifiers refers to an existing block).
The data to write does not overlap specified maximum and minimum
limits (each writeable register has its own maximum and minimum limit
according to the Type, Limits, Format Table, Table C–1); If it detects
errors, the write operation fails and a DIAGNOSTICS message will be
activated.
REMARK: In a write operation, if the block identifier refers to a read
block (0,1,2,3) only the header of the telegram is interpreted. The data are
ignored.
