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. |

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.

|
|
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: Please fill in the field when it is necessary. Dialing times: 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.

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 |

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 peripheral for long distance connection. The communication function is the same as COM2 except communication interface. Note: PLC will set that COM2 is occupied by RS-422 card and built-in COM2 (RS-485) function will be invalid after inserting this card. Refer to following for system connection.

When two built-in COM1(RS-232) and COM2 (RS-485) are not enough for use, you can add one COM by this card (number is 3 and is called COM3. There are two interfaces, RS-232 and RS-485, for you to use. Its general function is the same as COM1 but communication baud rate is 9600/19200/38400 bps. PLC scan time will be added at least 0.8ms ~ 2ms due to COM3.
Usage limit: PC1 and PC2 can’t execute ladder diagram monitor function simultaneously when COM2 is slave mode and connect to PC1 with executing WPLSoft and COM3 also connects to PC2 with executing WPLSoft. But other communication function is normal. COM1 is out of this limit.
