7.4 Remote connection
7.4.1 Summary of remote connection
If XG5000 executed PC is located far from XGT-PLC, remote PLC program can be controlled for download, upload,
debugging, monitoring, etc. through remote connection function of Cnet I/F module. Especially in case that XG5000 is located
far away from PLC, PLC CPU can be conveniently accessible through remote function of XG5000. The remote connection
via Cnet module is available for both 2 cases of remote connection between Cnet modules where XG5000 and PLC are
directly connected via RS-232C and modem connection between XG5000 and PLC. For information about remote
connection through modem, refer to the Ch.7.5.
7.4.2 Limit of remote connection between Cnet I/F modules
Limit of remote connection between Cnet I/F modules is as follows.
(1) Communication type should be set as RS-232C, RS-422
note1)
.
(2) In case of remote connection, maximum supported remote connection stage is two.
(3) Standard setting of Cnet I/F modules should be same for remote connection.
(4) In case of XGR, remote connection is available when station number of extension drive module is set within 1~15.
[Figure 7.4.1] Remote connection between Cnet I/F modules
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.
