Overview of the Functional Changes
Below is an overview of the main functional changes.
• Improvement to the Operability on the Historical Trend Display
When changing to the all data display, the DX loads as much of the continuous data
as the display memory can hold and shows the data.
• Alarm Output Relay Action When the Alarm ACK Operation Is Executed
You can select the mode in which the alarm output relay is turned OFF when alarm
ACK is executed and remains OFF until the next alarm occurs.
• Addition of the Media FIFO Function
If not enough free space is available when saving a new data file to the CF card, files
are deleted in order from the oldest data update date/time to save the new file.
• Function That Automatically Assigns MW100s to Modbus Clients
When connecting MW100s to the DX using the Modbus/TCP communications, the
MW100 channels can be assigned automatically to the DX external input channels.
* Only on DX2000s with the external input channels (/MC1 option).
• NEMA4 Compliance (Only the Waterproof Construction)
The waterproof construction of the DX front panel complies with the NEMA4 standard.
