REDUNDANT SYSTEM NETWORKS
(3) Line redundant system
The line redundant system allows the system configuration using 2 lines, and either of
the lines is used for slave station control. When an error occurs at the controlling line,
the control is inherited to another line.
(4) Station number setting
Set the station number of the PROFIBUS-DP master module with GX Developer and
GX Configurator-DP.
For details of setting method, refer to the following manual.
PROFIBUS-DP Master Module User's Manual
(5) Startup order of system A and system B
When using the PROFIBUS-DP master module, startup order of system A and system
B is unrestricted.
After the both system is started up and assigned their system (Control system/
standby system), data link is started.
(6) Precautions when using the PROFIBUS-DP master modules in
redundant system
(a) Function version of the PROFIBUS-DP master modules
Use the PROFIBUS-DP master modules of function version D or later.
(b) GX Developer version
Use GX Developer version 8.17T or later.
(c) At redundant system startup
• Check for an error of the PROFIBUS-DP master module at local station error
information area (Un\G23071).
For local station error information area, refer to the following manual.
PROFIBUS-DP Master Module User's Manual
• When there is an error, clear the error to perform system switching.
(d) Continuing each function of the PROFIBUS-DP master module
For precautions to continue each function of the PROFIBUS-DP master module,
refer to the following manual.
