Explanations:

To set up the Slave IP address for data exchange manually, write “0” into CR#28 first before setting up the destination IP. For example, if the user wants to set the destination IP address to

192.168.0.2, write H’0002 to CR#25 and H’C0A8 to CR#26. (K192 = H’C0, K168 = H’A8, K0 =

H’00, K2 = H’02).

C R # 2 8 :

Destination Slave ID

Explanations:

When you set up the Salve ID (i.e. K1 ~ K255) for data exchange, DVPEN01-SL will automatically search for the corresponding IP address from the Slave IP list. For example, if the

ID is set as “0”, the value in CR#25 and #26 will be regarded as the destination IP.

C R # 2 9 ~ 4 8 :

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).

4.3 Numbering of Left-Side Modules

After DVPEN01-SL is installed properly, you need to compile the PLC program to control the special I/O module. PLC offers FROM instruction (for reading) and TO instruction (for writing) to control the control registers

(CR) in the special I/O module.

Numbering of the modules: Every special I/O module connected to PLC MPU has a No. to allow you to know which module is which when compiling the PLC program. The first special I/O module attached at the left hand side of the PLC MPU is numbered as K100, the second as K101, the third K102, and so on.

7. Time Zone:

A time zone is a region of the Earth that has adopted the same standard time, usually referred to as the local time. Most adjacent time zones are exactly one hour apart, and by convention compute their local time as an offset from Greenwich Mean Time (see also UTC). Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes

(wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighboring zones is then exactly one hour different. However, political and geographical practicalities can result in irregularly shaped zones that follow political boundaries or that change their time seasonally (as with daylight saving time), as well as being subject to occasional redefinition as political conditions change. You should choice the Time zone that you are.

The first step for all the network equipment to connect to the network is to have its own IP address (Internet

Protocol). The IP address is like a number for every network equipment to be identified in the network.

Setting up DVPEN01-SL Network

1. IP configuration:

There are two types of IP, static IP and DHCP.

Static IP: Preset or manually modified by the user.

DHCP: Automatically updated by the server. There has to be a server in the LAN.

IP

Static

DHCP

Explanation

The user enters the IP address, subnet mask and gateway.

DHCP server offers the IP address, subnet mask and gateway.

2. IP address:

IP address is the location of the equipment in the network. Every equipment connected to the network has to have an IP address. Incorrect IP address will result in connection failure on the equipment or even other equipment. Ask your ISP for questions about IP address setup. The default

IP for DVPEN01-SL is 192.168.1.5.

3. Subnet mask:

Subnet mask is an important parameter for setting up the subnet, used for seeing if the destination

IP and the local equipment are in the same subnet. If not, the equipment will send the packet to the gateway, and the gateway will send the packet to another subnet. Incorrect setting may cause the destination equipment unable to communicate with DVPEN01-SL. To see if your setting is correct, conduct bitwise AND operations between your IP and subnet mask and destination IP and subnet mask. If the two values obtained are the same, the two IPs are in the same subnet. The default subnet mask of DVPEN01-SL is 255.255.255.0.

4. Gateway:

Gateway is the gate for two different subnets, allowing the two ends in different subnets to communicate. For example, if the LAN has to be connected to WAN, it will need a gateway to bridge the communication. The IP of the gateway has to be in the same subnet as DVPEN01-SL. The default gateway IP address of DVPEN01-SL is 192.168.1.1.

5.4 Setting up E-Mails

E-mail is the abbreviation of electronic mail, which transmits mails through the network. DVPEN01-SL has

E-Mail functions for the user to pre-save a segment of text messages, which can be a descriptive message or error message, into the subject of the E-Mail. When the E-Mail is triggered, DVPEN01-SL will send the messages to the user by E-Mail.

DVPEN01-SL offers 4 sets of E-Mail information, and you can self-define the register or bit information to be read. When the trigger occurs, DVPEN01-SL will add the set register or bit present value read to the E-Mail.

Every set of E-Mail information is able to contain maximum 100 continuous register data.

IP filter is used for restricting the connection of the network in case some uncertain IP will cause errors. Only the IP set within a certain range can establish a connection. Other IPs will be rejected.

„

Setting up IP filter

1. Enable IP Filter Function:

Check the box to enable IP filter.

2. IP:

IP addresses that are allowed to establish connections. Maximum 8 IPs are allowed.

3. Netmask:

The subnet of the IP is allowed to establish a connection. To see whether the destination IP is allowed, conduct bitwise AND operations between the allowed IP and subnet mask and destination

IP and subnet mask. If the two values obtained are the same, the destination IP is allowed by the IP filter. For example, assume the IP is 192.168.0.1 and subnet mask 255.255.255.255, the only one IP allowed to establish a connection is 192.168.0.1. If the subnet mask is 255.255.255.0, the IPs allowed to establish connections will become 192.168.0.0 ~ 192.168.0.255.

ARP (Address Resolution Protocol) is used for obtaining the MAC address corresponding to the IP address in data transmission. For example, there is a datum to be sent to 172.16.155.250, but you do not know the corresponding MAC address. You can use ARP to look up the MAC address by IP address, and the corresponding MAC address will be saved, so you do not need to look it up again when sending the next datum.

DVP-PLC Operation Manual

27

Ethernet Communication Module DVPEN01-SL

Therefore, if you do not know the MAC address, you will have to spend some time looking up the MAC address.

If you want to enhance the transmission efficiency, use static ARP table to save time. For example, assume IP:

192.168.0.1 and MAC: 00:14:22:56:0F:7F. As long as there are data sent to 192.168.0.1, you will get the MAC address from the table.

Explanations:

The data exchange will be executed every one second.

Write “0” into CR#28, and PLC_B will use CR#25 ~ CR#26 as the IP address of the destination

PLC.

Write the IP address of PLC_A into CR#25 and CR#26. The first two IP codes (192.168 =

H’C0A8) should be written into CR#26, and the last two IP codes (0.4 = H’0004) into CR#25.

Write the data in RTC into CR#29 ~ CR#35.

Write “1” into CR#13 to start the data exchange.

CR#14 = 2 refers to successful execution. CR#14 = 3 refers to failed execution.

2. Compile the ladder diagram for PLC_A and download it to PLC_A.

Write “0” into CR#28, and PLC_B will use CR#25 ~ CR#26 as the IP address of the destination

PLC.

Write the IP address of PLC_A into CR#25 and CR#26. The first two IP codes (192.168 =

H’C0A8) should be written into CR#26, and the last two IP codes (0.4 = H’0004) into CR#25.

Write the Modbus address of D0 (H’1000) in PLC_A into CR#81 and CR#84.

Write the Modbus address of D100 (register of RTC) (H’1064) into CR#86.

Write the number of registers K7 into CR#85.

Write “1” into CR#13 to start the data exchange.

CR#14 = 2 refers to successful execution. CR#14 = 3 refers to failed execution.

Once the data exchange is successful, the values in D1313 ~ D1318 in PLC_B will be written into

D0 ~ D6 of PLC_A.

Application

Network requirement

Compiling Modbus instruction by PLC_B, making Y0 of PLC_A flashing

(1) Adopt static IP.

(2) IP of PLC_A: 192.168.0.4

(3) IP of PLC_B: 192.168.0.5

(4) Update from PLC_B to PLC_A

(5) Use Modbus instruction 050500FF00 to set “On” Y0.

(6) Use Modbus instruction 0505000000 to set “Off” Y0.

(7) Y0 goes between On/Off once every one second.

1. See 6.1 for how to set up the communication.

2. Compile the ladder diagram in the MPU and download it to PLC_B. See below for the program design.

We do not need to write any corresponding ladder diagram into PLC_A.

Explanations:

The data exchange will be executed every one second.

Write the IP address of PLC_A into CR#117 and CR#118. The first two IP codes (192.168 =

H’C0A8) should be written into CR#118, and the last two IP codes (0.4 = H’0004) into CR#117.

Set CR#111 as “1” to enable the 8-bit mode. The Modbus instruction is stored in the low byte of

CR#120 ~ CR#247.

Write Modbus instruction into CR#120 ~ CR#125. CR#120 is the Modbus address.

Write the length of the instruction into CR#119.

Write “1” into CR#115 to start the execution of Modbus TCP instruction.

CR#116 = 2 refers to successful execution. CR#116 = 3 refers to failed execution.

If the execution is successful, Y0 on PLC_A will go between On and Off every one second.

6.14 RTU Mapping

Application

Network requirement

Using RTU mapping to read/write the remote digital I/O and analog I/O registers.

DVP28SV+DVPEN01-SL Æ RTU-EN01+DVP06XA+DVP16SP

(1) Adopt static IP.

(2) IP of DVPEN01-SL: 192.168.1.90

(3) IP of RTU-EN01: 92.168.1.91

(4) Use DCISoft for RTU-EN01and check 10 mapping data for read and 10 mapping data for write.

(5) Set up the mapping start address and number of data for RX, RY, RCR (read) and RCR

(write) at DVPEN01-SL.

(6) Enable the mapping function in DVP-SV PLC at DVPEN01-SL. Use M2000 and D2000 in DVP-SV to read and M3000 and D3000 to write the value in the remote RTU-EN01.

54

DVP-PLC Operation Manual

Ethernet Communication Module DVPEN01-SL

1. See 6.1 for how to set up the communication.

2. Use DCISoft for RTU-EN01 to set up the mapping CR for read/write.

3. Use DCISoft for DVPEN01-SL to set up the mapping start address and number of data. RX: M2000 ~

M2009, RY: M3000 ~ M3009, RCR Read: D2000 ~ D20009, RCR Write: D3000 ~ D3009

4. Edit the ladder diagram in the MPU and download it to DVPEN01-SL. See the program design as shown below:

DVP-PLC Operation Manual

55

Ethernet Communication Module DVPEN01-SL

Explanations:

1. Enable mapping: CR15 = 1

2. Disable mapping: CR15 = 0

3. Once CR#15 is enabled, M2000 ~M2009 and D2000 ~ D2009 will read the data, and M3000 ~ M3009 and D3000 ~ D3009 will read the present value before starting to write.

4. During the execution of mapping, other devices are not allowed to modify the value in the mapped register.
