■Array specification
Specify the details of arrays for number of arrays specified to array points.
Specify the following items for each array.
• Label name length, label name: Specify the label name and label length of a global label. (Page 125 Labels)
• Unit specification: For the bit type labels, specify the unit specification in bit units (0). As for other than bit type label, specify
the unit specification in byte units (1).
• Array data length: Specify the data size of array in the unit specified with "Unit specification." (Page 133 Data length,
unit specification)
• Fixed value: Fixed to '0'
Data stored in response data
■Array points
The same data as request data are stored.
■Array data
The read array data is stored for number of arrays which are specified with array point.
The following items are stored for each array.
• Data type ID: The data type of the label name is stored with the defined ID. (Page 132 Data type ID)
• Unit specification: For the bit type labels, specify the unit specification in bit units (0). As for other than bit type label, specify
the unit specification in byte units (1).
• Array data length: Specify the data size of array in the unit specified with "Unit specification." (Page 133 Data length,
unit specification)
• Read data: The value of the read label is stored. (Page 135 Read data, write data)
When unit specification is bit specification, read data are stored in 16-bit (2-byte) units.
