DVP-256FM

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
on. If this switch is Off, memory card will be invalid. And it is
invalid to change the switch when PLC is power on. All
memory data read/write action will be valid when switch is On.

╳

○

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.

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.

WPL working area memory card [program]

It can copy program that edited by WPL to memory
card or copy PLC program in memory card to WPL
working area.

WPL working area memory card [commentary]

It can copy commentary in WPL to memory card or
read commentary from memory card (commentary
in memory card can be only loaded in WPL working
area. It can’t be loaded in PLC EH MPU and there
is no area for saving commentary in EH MPU.)

Following is the operation for each item and relative cautions:

Data transmission between PLC memory card
Function selection

PLC => 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.

memory card => PLC (PLC must be in STOP mode)

It will compare password in memory to password in PLC before executing. If
passwords are not the same, it can’t read data.

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

Data is transmitted between WPL working area memory card [program]
Function selection

WPL working area => memory card

a) If you don’t input any words in password field (password field is blank),

password in memory card will be clear after pressing Enter button (no
matter it has password or not before).

b) If you input new password in password field, password in memory card

will be protected by this new password.

memory card => WPL working area

If there is password for memory card, you will be asked to input password
when executing this function. If you don’t input password or input error
password, it will have error message and can’t read data.

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

Data transmitted between WPL working area memory card [commentary]
Function selection

WPL working area => memory card

a) You can select devices to save in memory card. Default is all devices.

After you select, all device you select with commentary will save in
memory card.

b) For device M and D, special D(D1000~D1999) and special

M(M1000~M1999) won’t be wrote into memory card.

c) The commentary capacity in memory card is 32KB. It can save 16000

Chinese words or 32000 letters.

Memory card => WPL working area

To upload commentary in memory card to WPL working area for user to edit
or modify.

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

Installation and Maintenance

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.

Function card installation – Please put function card into slot vertically and tighten accessory screws into

correct position.

Remove function card

Backup memory card installation (change switch to On or Off by requirement)

and removal

Removal

Check for finishing installation

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.

Application

All kinds of function card provided by DVP series solve the problem that happened in PLC application.
For example:

Usage timing and application requirement

solution (correspond to

function card model name)

When system specification is modified, there are not enough points for
use. And you need only 1~4 input points or 1~2 output points.

Use DVP-F4IP or
DVP-F2OT

Output point of MPU is relay and you need 1~2 points more with transistor
type.

Use DVP-2OT

There is space limit for installing and need to deal with analog signal.

Use DVP-F2AD or
DVP-F2DA

You need 1~2 analog output points to control AC drive speed.

Use DVP-F2DA

Small control system and need 1~2 analog input points.

Use DVP-F2AD

You need to connect PLC to PC and HMI and also control AC drive.

Use DVP-F232S or
DVP-F485S

There are many PLCs and need to download program quickly. (copy PLC) Use DVP-256FM
When parameters want to set by DIP switch without occupy any input
points.

Use DVP-F8ID

When built-in COM 2 is RS-485, but what you need is RS-232 or RS-422. Use DVP-F232 or

DVP-F422

When remote control PLC is by MODEM.

Use DVP-F232

When there are 3~8 variables needed to modify by requirement very
often.

Use DVP-F6VR
