1 WARNING

Always read this manual thoroughly before using Function Extension Card.

This instruction provides electrical specification, function specification, wiring and basic program

design. For detail program design and instruction explanation information refer to PLC Application

Manual (programming).

This is an OPEN-TYPE. When installing, you should turn MPU power off and have static

electricity protection, such as wear antistatic gloves, to avoid damage those components on

function extension card caused by statics.

This instruction is for DVP series function extension card. Please find out your order model in the

following for correct usage.

Thank you for choosing DELTA’s PLC extension card of DVP-EP/EH Series. There are analog

input/output card (AI/AO), digital input/output card (DI/DO), extension card for communication port and

memory card. Refer to following table for detail.

 Application example for connecting in Master mode

After inserting DVP-F232 card into MPU, you can use WPL to monitor or upload or download via MODEM connection. First, you should connect PC and PLC to MODEM separately at the two end of network and turn MODEM power on to operate by following steps.

WPLSoft is executing

MODEM

MPU built in COM1(RS-232) and COM2(RS-485). When connecting RS-232 to PC or other peripheral, such as MODEM, by using COM2, you can use this extension card. The communication function is the same as COM2 except communication interface, i.e. there are Slave mode and Master mode for you to choose. Note: PLC will set that COM2 is occupied by RS-232 card and built-in COM2 (RS-232) function will be invalid after inserting this card. Refer to following for system connection.

STEP 1: Setting M1184=On on PLC side (start-up MODEM) STEP 2: Setting M1185=On (start-up PLC’s MODEM initialization) STEP 3: Check the result of MODEM initialization: M1186=On means succeed to initial. M1187=On

means fail to initial.

STEP 4: After initialing successful, WPL software can be ready for connection on remote PC side. WPL

connection method: setting -> modem connection (you need to install modem’s driver first) -> to get dial connection dialog box and then fill in dial information as following.

If you dial a number to access an outside line, what is it? Please fill in this field when it is necessary.

Telephone number

: if there is any area code or city code, you don’t need to put anything for distinction. Only key the figure one by one directly. For example: 88633626301

Extension number:

Dialing times:

Please fill in the field when it is necessary.

setting redial times when it is fail to connect.

After finishing input, execute dialing to start connection.

After dialing connection successfully, dial connection dialog box will disappear automatically. Now, you can monitor remote PLC via WPL. If there is remote control signal detected on PLC side, M1188 will be On and user can know if PLC is monitored by remote control via this special M.

Note:

1. Communication baud rate can’t be changed during MODEM connection. MODEM connection baud rate on PLC side is fixed to 9600bps and can’t be modified.

2. The MODEM that connected to PLC must provide Auto Answer (AA) function. Communication baud rate for MODEM at two end should be 9600bps and higher.

3. EP/EH series special M definition for MODEM connection: (following special M is valid when PLC is RUN/STOP.

Device Function Explanation Remark M1184 Start-up MODEM When M1184=On, following actions are valid.

M1185 Start-up MODEM initialization This flag will be Off after finishing initialization. M1186 Fail to initial MODEM When M1185=On, M1186=Off. M1187 Succeed to initial MODEM When M1185=On,M1187=Off. M1188 Display if MODEM is connected or not On means in connection

4. Additional explanation on PLC side:

a) It must use with RS-232 card when connecting MODEM on PLC side. If not, above special M

are invalid.

b) You must set M1185=On to initial MODEM after MODEM start-up (M1184=On). If not, it can’t

start-up MODEM auto dial function on PLC side. c) MODEM will enter auto dial mode after initialization. d) MODEM will enter to ready for dial mode on PLC side after remote PC stops connection. If user

turn MODEM power off now, it should need to initial at the next time when turning on MODEM. e) The initial format that used to MODEM on PLC side are ATZ and ATS0=1.

User can use COM2 to connect RS-422 and HMI or other

256FM is a data backup memory card. There is a switch on it and PLC will check the state of this switch when PLC is power

DVP-256FM

It will check password during date copy. If there is password in memory card, it will also be copied to PLC and PLC will be locked. See flowchart at the right side.

There are several sections for copy data in memory to PLC as shown in the following.

Therefore, 256FM card can be used for data backup and PLC copy. It can write PLC major data block (according to left table) into memory card according to following two steps. Step 1: finish setting program parameters, file register parameters or other relative latched parameters by using WPLSoft or HPP02. Step 2: choose communication -> communication for memory card in WPLSoft software. You can insert this memory card into other EH MPU to finish PLC copy function quickly. After this PLC MPU is power on, the data in memory card will upload to PLC relative data area. (only for DVP-EH MPU (32 points and more))

Those data in 256FM card can be read/wrote by using WPLSoft or HPP02 but there is limit for editing or read/write data. For HPP02, it can only read/write the DATA in program area and file register area.

When inserting memory card in PLC, you can read/write data in memory card by using WPL. The operations are in the following: (please confirm that switch on memory card is On before PLC is power on. And also confirm that connection is successful to read/write data in memory card.

Using WPLSoft to select communication -> communication for memory card

There are three modes:  PLC memorymemory card

You can copy data in memory card to PLC or copy data in PLC to memory card.

a) If password in PLC is unlocked but password in memory card is locked,

data will be wrote into memory card and password in memory card will be disable after executing PLC => memory card.

b) If password in PLC is locked and no matter password in memory card is

locked or not, data and password in PLC will be wrote into memory card after executing PLC => memory card.

3 Installation and Maintenance

Note: “Lock state” means password in memory card is locked.

Please make sure that PLC is power off and open extension slot cover before installing or removing function card or memory card. The installed position of function card and memory card are shown at the right side. Please attach terminal

label shipped with package on correct terminal to avoid error wiring.

After PLC is power on, connect PLC to WPLSoft at PC side. In WPLSoft, select view -> working area and then select connected model to connect. At this time, WPLSoft will detect configuration of PLC MPU system and show the result, including categories of function card and state of memory card (On or Off), in working area. Refer to WPLSoft user manual for detail.
