PCD235A101 Ethernet interface built-in

PCD235A101 hardware requirements and wiring and dial-up connection is basically corresponding, including MODEM, computer, PLC parameter settings are also the same as the above method, the following only explains the private line connection and dial-up connection is different. PCD235A101 settings: PCD235A101 in addition to the requirements of dial-up connection, the most important point is that it must support the leased line. Now on the market for sale in some commercial PCD235A101 does not have a private line function, so the choice of MODEM should be contacted with the manufacturer to confirm its support for private line mode. PCD235A101 parameters according to the previous requirements were set up, in addition to the need to PCD235A101 set to a private line mode, and will be set to one of the calling (Original), the other set to be called (An), the other set to be called (An). In addition, you need to set PCD235A101 to leased line mode, and set one of them as the caller (Original) and the other one as the called (Answer). Some MODEMs supporting leased line can be set on the front panel by pressing keys or other hardware settings. If you can’t set the hardware settings, you need to follow the method described in “Dial-up Connection” to set and store the settings with AT commands through “Hyper Terminal”.

Set up for 2-line leased line PCD235A101 set up is completed, respectively, with the host computer and PLC connected to a telephone line with RG-11 plugs at both ends into the PCD235A101 “LINE” port, and then the equipment will be powered on. CPT and SSS use: After PCD235A101 power on, the calling party (generally connected to the computer) will automatically initiate the call and establish a connection with the called party, you can observe the instructions on the panel of the MODEM (CD light) to PCD235A101 connected successfully. After successful connection, run SSS or CPT software on the computer and communicate with PLC according to HOSTLINK. That is to say, the dedicated connection is just to replace the serial communication cable between the computer and PLC under the HOSTLINK method with two PCD235A101s that can be connected automatically.
