Ethernet Communication Module DVPEN01-SL
DVP-PLC Application Manual
10
Storing the data to be transmitted to the remote MPU.
C R # 4 9 ~ 6 8 :
Data Receiving Buffer
Explanations:
Storing the data received from the remote MPU.
C R # 8 1 :
Read Address for Data Exchange
Explanations:
Setting up manually the Modbus address of the register for Slave data exchange. Only register
address is allowed (e.g. D0 = H’1000).
C R # 8 2 :
Read Length for Data Exchange
Explanations:
The number of receiving registers (K1 ~ K128) in data exchange.
C R # 8 3 :
Read Length for Data Exchange
Explanations:
Setting up the Modbus address of the register for Master data exchange.
C R # 8 4 :
Written-in Address for Data Exchange
Explanations:
Setting up manually the Modbus address of the register for Slave data exchange.
C R # 8 5 :
Written-in Address for Data Exchange
Explanations:
The number of transmission registers (K1 ~ K128) in data exchange.
C R # 8 6 :
Transmission Address for Data Exchange
Explanations:
1. Setting up the Modbus address of the register for Master data exchange.
2. Example: Write H’1000 (D0) into CR#81, K1 into CR#82, and H’1064 (D100) into CR#83. If
the data exchange is successful, the value in D0 of the Slave will be written into D100 of the
MPU. Or write H’1002 (D2) into CR#84, K4 into CR#85, and H’1008 (D8) into CR#86. If the
data exchange is successful, the value in D8 ~ D11 of the Master will be written into D2 ~ D5
of the Slave. Both sending and receiving can be executed at the same time. When the values
in CR#82 and #85 are both “0”, DVPEN01-SL will use the default registers (CR#29 ~ CR#68)
and number of registers (K20).
Network Settings
C R # 6 9 :
DHCP/Static IP
Explanations:
You can select either DHCP or Static IP. When the CR value is set as “0”
Æ
Static IP; When the
CR value is set as “1”
Æ
DHCP (dynamic IP).
