1.2 Characteristics
The XGT Cnet I/F module is serial communication device supporting the RS-232C and RS-422(485) protocol and has the following
characteristics.
(1) Since the user can write directly, it is easy to connect with other company’s products
(2) Because communication speed and communication mode (protocol) are directly specified by user using XG5000 operative in
Windows environment, connection with other company’s products is easy.
(3) 3 types of Cnet I/F modules are available: RS-232C 2Port, RS-422(485) 2Port, RS-232C 1Port/ RS-422 1Port.
(4) With the separate operation based on each channel, the protocol data specified by user is controlled by CPU module, which
allows the replaced communication module directly to be applied without additional setting or downloading.
(5) Read/Write is available by using the dedicated protocol.
(6) Dedicated communication function suitable to multi-drop configuration connectable up to 32 units is provided if RS-422/485
channel used.
(7) With modem communication function built-in, remote PLC can be controlled by XG5000 connection, dedicated communication,
and user defined communication.
(8) Various communication speeds can be set
- RS-232C : 300bps ~ 115,200bps / RS-422 : 300bps ~ 115,200bps.
(9) 1:1/1:N/N:M communication(if RS-422 channel used) is available.
(10) Communication types of full-duplex (RS-422/RS-232C) and half-duplex (RS-485) are supported.
(11) With satisfactory self-diagnosis function and Loop-Back diagnosis function, diagnosis of errors is easy to make.
(12) Dedicated communication and Modbus Server/Client functions are available.
(13) Remote connection during communication between XGT Cnet I/F modules is available.
Note1)
Note
Note1) Remote connection during communication between XGT Cnet I/F modules is supported when O/S version of
XGT Cnet I/F module is 2.5 or above. Features are as follows.
(1) For communication type, only RS-232C, RS-422 method is supported. In case of remote connection using
RS-485, remote connection is only available when the P2P link on the online menu of XG5000 is disabled.
(2) Remote connection is supported regardless of active mode.
(3) Remote connection during communication is affected according to TRX period and an amount of data
- In case TRX period is short or amount of data is huge, disconnection may occur.
