Discrete data handling capability in the generic channel blocks

The generic blocks are configured with the necessary parameters to specify the particular byte and bit necessary to convert discrete I/O data from/to integer format.

Application Constraints

The data representation of various PROFIBUS DP devices was considered in the design of the generic blocks. As a result, these blocks can interface with most, but not all, PROFIBUS DP devices. The following constraints bound the scope of application: · · The generic blocks provide the CEE with I/O data of FLOAT64 and BOOLEAN data types only, for analog and discrete devices, respectively. Note that I/O parameters can be connected to blocks such as the TypeConvert block in order to effectively interpret other data types. Although analog/numeric data is exposed to the control process in the FLOAT64 data type, as described above, the generic blocks interpret/package all numerical data in integer format for transport from/to PROFIBUS. The following integer formats are supported for data transport by the generic channel blocks: o Signed or unsigned 16 bit integer (most commonly used) o Signed or unsigned 8 bit integer o Signed 32 bit integer Experion LS I/O Specifications and Technical Data, EP03-110-400, V2, January 2012 67 · · ·
