Communication Considerations

About Communication IntervalData UpdateThe DX data is updated in a scan interval. Even if a PLC accesses the data at shorter intervals than the DX scan intervals, the data is updated only at scan intervals.

Communication IntervalA PLC should access the DX at intervals of 125 ms or longer.

* This is required to maintain compatibility with other protocols supported by the DX than EtherNet/IP.

Access to Non-existent DataIf non-existent data is accessed, either of the following operations occur.• 0 is read if non-existent data is read.• Nothing is done if non-existent data is written.

When the DX Data Type Differs from the Data Type Specified in a CommandEach data on the DX has a fixed data type.Data on the DX which includes special data accessed using the same data type is transmitted unchanged. Data on the DX accessed using a different data has its data type converted. The following explains the conversion rules:

Reading Data on the DXDX Data type to be specified in a commandType Data type INT16 INT32 FLOATMeasurement channel

INT16 The data is read without change.

The data is converted into INT32 (including special data).

The data is computed based on the decimal point information set in each channel.*1

The data is read without change.

The data is converted to INT32. The data is read without change.

External input channel (for reading)

INT16 The data is read without change.

The data is converted into INT32 (including special data).

The data is computed based on the decimal point information set in each channel.*1
