①: DVP-SV MPU sends out explicit request message to DVPDNET-SL according to WPL program.
②: DVPDNET-SL sends out request message to the target equipment.
③: The target equipment processes the request message and responds DVPDNET-SL.
④: DVP-SV MPU stores the response message from DVPDNET-SL to D register. One explicit message
transmission is therefore completed.

5.2 Structure of Explicit Message
You can edit explicit messages in “explicit request message editing area” and “explicit response message
editing area”. See the table below for the corresponding relation between the two areas and PLC devices. If
you transmit the request message to be sent out to D6250 ~ D6281, DVPDNET-SL will fill the response
message to D6000 ~ D6031.
PLC device Mapping area Mapping length
D6000 ~ D6031 Explicit response message editing area 64 bytes
D6250 ~ D6281 Explicit request message editing area 64 bytes

Command: Fixed to “01Hex”.
ReqID: The request ID. Whenever an explicit message is sent out, the message will be given a ReqID
for DVPDNET-SL to identify. For the next explicit message to be sent out, you have to change the ID
number. ReqID = 0 indicates that DVPDNET-SL will not send out explicit message. Range of ReqID:
00Hex ~ FFHex.
Size: The length of the message, starting from D6253. The high bytes of D6255 are reserved. When
the data length is being calculated, D6255 is counted as 1 byte. The maximum data length is 58 bytes.
Errors will occur when the length is longer than 58 bytes. Unit: byte.

length is longer than 58 bytes. Unit: byte.
See the table below for the meanings of Status (status codes):
Status Explanation
0 No explicit message is sent out.
1 The communication of explicit message is successful.
2 The explicit message is being sent out.
3 Error: No response from the target equipment.
4 Error: Command is invalid.
5 Error: Size of request message is invalid.

3) Notes:
DVPDNET-SL can only send out 1 explicit message at a time.
Before sending explicit message by using WPL program, we suggest you clear the request message
editing area and response message editing area to 0.
If the slave responds with standard error code, and DVPDNET-SL also consider the communication
being successful, “The communication of explicit message is successful.” will indicate that the
communication has been completed successfully.

6 Bit-Strobe Command
6.1 Principle of Bit-Strobe
Bit-strobe is one of the standard I/O transmission methods for DeviceNet. The length of command is fixed to 8
bytes (i.e. 64 bits), and every bit corresponds to a slave.
PLC
device
D6282 Node 15 Node 14 Node 13 … Node 1 Node 0
D6283 Node 31 Node 30 Node 29 … Node 17 Node 16
D6284 Node 47 Node 46 Node 45 … Node 33 Node 32
D6285 Node 63 Node 62 Node 61 … Node 49 Node 48
When b0 of D6282 = 0, the node 0 equipment will be selected, and it will need to respond with a message to
the master. When b0 and b1 of D6282 = 0, the node 0 and node 1 equipment will be selected, and they will be
to respond with a message to the master.
In the bit-strobe mode, the master will not send control data to the slave node. However, when its

7 Display of Node Status on Network
7.1 Display of Node Status in Scan List
This function is to monitor if DeviceNet slave is offline or not. DVPDNET-SL does read-time monitoring to the
nodes in the scan list and maps the status of every node to a bit. You can acquire the node status by
monitoring D6032 ~ D6035. See the table below for the corresponding relation between PLC devices and the
nodes on the network:
PLC
device
D6032 Node 15 Node 14 Node 13 … Node 1 Node 0
D6033 Node 31 Node 30 Node 29 … Node 17 Node 16
D6034 Node 47 Node 46 Node 45 … Node 33 Node 32
D6035 Node 63 Node 62 Node 61 … Node 49 Node 48
When the node in the scan list is normal, the corresponding bit will be off. If the node occurs with abnormality,
its corresponding bit will be On.
b15 b14 b13 … b1 b0
7.2 Status of DVPDNET-SL
You can acquire the real-time status of DVPDNET-SL by monitoring D6036. When DVPDNET-SL runs
normally, D6036 = 0. When DVPDNET-SL is being initialized, the high byte of D6036 = 1 and the low byte = 0.
When error occurs in DVPDNET-SL, the high byte of D6036 = 2. For detailed error information, please refer
to the error codes, i.e. the low byte of D6036.
