Instruction Sheet

Warning

 This Instruction Sheet only provides descriptions for electrical specifications, general specifications, installation and

wiring.

 DVPDNET-SL is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust,

humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required for opening the enclosure) in case danger and damage on the device may occur. Do NOT tough any terminal when the power is switched on.

message response.

Step A: PLC transfers the explicit message data to DNET scanner.

Step B: DNET scanner sends the explicit request to target devices.

Step C: The target devices process the request and send the response to DNET scanner.

Step D: PLC receives the explicit response data.

Explicit Message Structure

The explicit message is controlled by explicit message program request area and explicit message program

response area. The two areas are mapped to D registers in PLC.

The user can move the data of explicit request message to D6250 – D6281 and DNET scanner will fill the

response data into D6000 – D6031. The explicit message request format is shown in the table below.

 ReqID: When sending every explicit message, the user has to assign a Request ID for this explicit message.

DNET scanner identifies the response message by this ID. Therefore, the user has to change the ID value

when completing an explicit message communication for the next transmission.

1. Make sure the scanner is powered.

2. Make sure at least 1 node or more are

communicating in the network.

E2 Salve device in scan list does not exist.

E3 Module fails to transmit a message

Error detected in sequence of fragmented I/O

messages from device.

Slave device returns error response when the

scanner attempts to communicate with it.

E6 Data size returned is bigger than expected.

The desired slave device does not exist in the

network. Add device to the network.

Make sure that the connection is valid and check if
