Setting of Port Device

 

When you select button( rear of Device setting area) of 'Edit Port File' dialog box, the dialog box is shown such as <Figure 1>.

'Port Device' menu use for setting Device Type and parameters.

<Figure 1>  Example of Port Device dialog box

Setting parameters of Port Device are as follows : 

Device Type = selection of device type for communication.

None : direct connection or internal control device at communication driver.

example) ISA, PCI card, OPC, ...

Com Port : RS232C, RS-422, RS-485 communication.

use Tx Flow and Rx Flow, RTS/DTR Delay when half duplex RS-422, RS-485, etc.

Modem : dialup modem communication. ( set Com Port, Baud rate,Parity, Data Bit, Stop Bit )

TCP/IP : TCP/IP network communication.

UDP/IP : UDP/IP network communication.

TeleDevice : type of Modem device.

NetClient : device for 'NetClnt.exe' program. ( get Server data with NetServ.exe program )

SharedMemory:device for 'OpcClientMain.exe' program to communicate with OPC Server.  

Com Port  = com port number, can select COM1~COM256.

Com Baud = selection of baud rate, 300 ~ 256000 bps (bits per second ).

Parity Bit = selection of parity bit among None, 1Bit Odd, 2Bit Even.

Data Bit = selection of data bit between 8 Bit, 7 Bit.

Stop Bit = selection of stop bit between 1 Bit, 2 Bit.

Tx Flow =transmit flow control( handshaking ) method selection of Tx Flow among TxON, TxRTS, TxDTR for serial communication(RS-232C, RS-422/485, etc).

TxON : always open Tx Gate, full duplex(RS-422/485) serial communication.

TxRTS : RTS On when data sending, RTS Off after data sending. ( normally half duplex serial communication )

TxDTR : DTR On when data sending, DTR Off after data sending. ( normally half duplex serial communication ) 

Rx Flow = transmit flow control( handshaking ) method selection of Rx Flow between RxON, RxECHO for serial communication(RS-232C, RS-422/485, etc).

RxON : always open Rx Gate, full duplex(RS-422/485) serial communication.

RxECHO : sending code that has been received to Rx.

RTS Toggle = selection auto RTS signal flow control(handshaking).

RTS/DTR End Delay = RTS, DTR On waiting time after sending data when using Tx Flow( TxRTS, TxDTR ).

unit : operation time of computer, differ according CPU speed.

example) when Pentium III 450Mhz P : 10000 = about 10 milli second.

Read : waiting time for reading routine.

Write  waiting time for writing routine. 

RTS/DTR Start Delay = RTS, DTR On waiting time previous sending data when using Tx Flow( TxRTS, TxDTR ).

unit : operation time of computer, differ according CPU speed.

example) when Pentium III 450Mhz P : 10000 = about 10 milli second. 

Read : waiting time for reading routine.

Write  waiting time for writing routine. 

TCP/IP, UDP/IP = IP Address and Service Port setting of PLC or controller.

IP  Address : IP Address of PLC or controller.

Service Port : TCP/IP or UDP/IP Service Port of PLC or controller.

example) 2004 for TCP/IP of GLOFA PLC,

2005 for UDP/IP of GLOFA PLC.

TeleDevice = setting when selecting 'TeleDevice'.

Please select 'Option' botton for TeleDevice setting.
