PROCEDURES BEFORE OPERATION
This chapter describes the procedures before operation.
1.
Self-diagnostics test
Turn on the power and perform the self-diagnostics test on the RJ71PB91V alone. ( MELSEC iQ-R PROFIBUS-DP
Module User's Manual (Application))
When no errors are detected, the LEDs and the relevant buffer memory areas behave as follows.
• ERR LED: Off
• Test results are stored in 'Offline test status area' (Un\G2258).
2.
Network configuration
Configure the system and set the parameters which are required for start-up.
• Wiring ( Page 32 WIRING)
• Parameter setting ( MELSEC iQ-R PROFIBUS-DP Module User's Manual (Application))
3.
Start of I/O data exchanges
Start I/O data exchanges of the PROFIBUS-DP network using either of the following procedures.
• Turn on 'Data exchange start request signal' (Y0) on the DP-Master.
• Click "Start/Stop PROFIBUS" of PROFIBUS Configuration Tool. ( MELSEC iQ-R PROFIBUS-DP Module User's Manual
(Application))
4.
Network diagnostics
Check that communications are performed normally. When communications are performed normally, the LEDs and the bits
corresponding to the relevant buffer memory areas on the DP-Master behave as follows.
• RUN LED: On
• ERR LED: Off
• BF LED: Off
• Bit corresponding to 'Slave status area (Normal communication detection)' (Un\G23040 to Un\G23047): ON
• Bit corresponding to 'Slave status area (Diagnostic information detection)' (Un\G23056 to Un\G23064): OFF
5.
Programming
Create a program. ( Page 35 COMMUNICATION EXAMPLE)
Precautions for starting up redundant system
For procedure to start up the redundant system, refer to the following.
 MELSEC iQ-R CPU Module User's Manual (Application)
■Self-diagnostics test
• Before performing the self-diagnostics test, change the operation mode of the redundant system to the separate mode (The
operation mode at the startup is the backup mode.), and stop the tracking transfer. ( MELSEC iQ-R CPU Module User's
Manual (Application))
• Perform self-diagnostics test for each DP-Master of both systems.
■Network configuration
• Set the FDL address of the DP-Master of the control system using "FDL address" in the "Master settings" window of
PROFIBUS Configuration Tool.
• Set the refresh using "CPU Device Access" in the "Master Settings" window of PROFIBUS Configuration Tool.
• Set the FDL address of the DP-Master of the standby system using "Standby System Master FDL Address" in the "Module
Parameter" window of the engineering tool.
Write the parameter settings including the above settings to the DP-Masters of both systems.
