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 construction
Configure the system and set the parameters which are required for start-up.
• Wiring ( Page 28 WIRING)
• Parameter setting ( MELSEC iQ-R PROFIBUS-DP Module User's Manual (Application))
3.
Start of data exchange
Start the data exchange of the PROFIBUS-DP network using either of the following procedures.
• Turn on 'Data exchange start request signal' (Y0).
• 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 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 31 COMMUNICATION EXAMPLE)
