COMMUNICATION

IP:

DHCP client is supported. Manual setting of IP address,

subnet mask, default gateway and DNS server available too.

Modbus/TCP slave:

Remote observation system via SCADA etc.

Number of connections 4

Modbus/TCP master:

I/O expansion with remote I/O, e.g. R3 or R7 series, is

available. Measuring points in multiple locations can be

handled collectively.

SLMP Client:

DL8 allows I/O expansion by connecting with the SLMP-

compatible CPU unit of Mitsubishi programmable-controller

MELSEC; and collectively handles data from measuring

points in multiple locations.

Web server function (Direct):

This unit can be a Web server, and 'Data,' 'Trend' and 'Event

Log' views are available from remote location.

Web server function (Cloud):

This unit can be an FTP client, and upload the Web files to a

cloud server.

Users can browse the cloud server.

Multiple users can access it at once without extra load at

the unit. (only browsing, operation not available.)

Analog input: 32 points

Discrete input: 64 points

Pulse input: 32 points

Diescrete output: 64 points

Analog output: 32 points (firmware version of the unit: 1.4.x

or later)

* For pulse input, only 32 bit data is available. It is not

available for the products using 16 bit data (model: R3-PA16

etc.).

ALARM OUTPUT (Type B, C, D & E)

Event can trigger an alarm contact at a discrete output

module.

•Transition of analog input zone

•Transition of pulse input zone

•Status change of discrete input

•Count up of discrete input

EVENT REPORTING E-MAIL (Type B, C, D & E)

Reporting e-mail function available at event or designated

time.

Encrypted communication is supported. (SMTP over SSL).

The DL8 turns a designated Do ON after transmitting the

report.

· Number of e-mail attention: 32

· Number of event report text: 32

· Number of regular report text: 1

· Channel status: AI, DI, PI, DO, AO status attachable to e-

mail

(DO and AO are available with firmware version of the unit

1.4.x or later)

· Output at transmitting failure: 1 point

LOGGING (Type C, D & E)

Log files in text format are stored into an SD card. The

number of logs depends on the free space of the SD card.

Log file: System log, event log, e-mail report log, channel
