Module label of buffer memory areas
The names of the module labels of the buffer memory areas are defined with the following configuration.
• "Module name"_"Module number"."Data type"_D"."Data format""Label name"_D
• "Module name"_"Module number"."Data type"_D"."Data format""Label name"_D.[Bit No.]
• "Module name"_"Module number"."Data type"_D"."Data format""Label name"_"Axis_D[ax]"
• "Module name"_"Module number"."Data type"_"Axis_D[ax]"."Data type""Label name"_D
■Module name
The module name indicates the model of the module.
■Module number
The module number starts from one and increments for identifying modules with the same module name.
■Data type
The data type indicates the type of a buffer memory area. The following shows the classification.
Data type
stnParameter
stnAxisMonitorData
stnAxisControlData
stSystemControlData
stInterruptSettingData
■Label name
The label name is unique for each module.
■Axis [ax]
Axis [ax] indicates the axis number corresponding to the module label. A numerical value from 0 to 1 is used for [ax] according
to the axis from 1 to 2. (Axis 1: 0, axis 2: 1)
■Data type
The data type indicates the size of a buffer memory area. The following shows the classification.
