Binary Data - Sony MG40 Series Command Reference Manual

5-3. Binary data

Th e binary data format is used in the cases below.
• When the function for continuous data transfer via Ethernet, which uses the TCP or UDP protocol, is
used
• When data is requested using CC-Link
Under the binary data format, any unit (a main unit or hub unit) to which even one valid axis is connected
is considered as valid, and 32-byte fi xed-length data is used for each unit.
All zeros are used for the status and data of an axis which is not connected.
When Ethernet is used:
Minimum data size: 1 valid unit (with 1 to 4 valid axes): 32 bytes
Hub unit
ID02 data
32 bytes
Maximum data size: 25 valid units (with 25 to 100 valid axes): 800 bytes
Main unit
ID00 data
32 bytes
Hub unit
ID01 data
32 Bytes
Hub unit
ID02 data
32 Bytes
|
Hub unit
ID31 data
32 Bytes
When CC-Link is used:
Since the size of the remote registers is 32 bytes, the data of a single designated unit is always designated
and acquired.
To acquire the data of a multiple number of units, issue the commands in sequence from the PLC to
acquire it.
Hub unit
ID05 data
32 Bytes
In order to synchronize the data of a multiple number of units, use the latch command, and then collect
the data of each unit using the memory data output command.
