Checking Warning Output (Process Alarm) - Mitsubishi Electric NZ2FTGN User Manual

Checking warning output (Process alarm)

Checks whether Process alarm has occurred from the I/O module corresponding to the warning output, and reads Process
alarm data of the content.
The I/O modules that support the warning output and their details are as follows.
• NZ2FTS-60RD4: Page 504 Warning output (Process alarm)
• NZ2FTS-60TD4: Page 516 Warning output (Process alarm)
• NZ2FTS-D62P2: Page 535 Warning output (Process alarm)
Process alarm cannot be checked from the Web server.
Setting the NZ2FT-EIP parameter "Process alarm" to "Enabled" allows detection of Process alarm of I/O modules.
The following describes assignment to the buffer memory, data configuration, and referring method of Process alarm data of I/
O modules.
Assignment to the buffer memory
Process alarm data is read in the same way as Diagnostic data. There is no assignment to the memory buffer.
How to check with the EtherNet/IP Configuration Tool for RJ71EIP91
Process alarm data of I/O modules can be checked by specifying the following items with the UCMM/Class3 communication
command of EtherNet/IP Configuration Tool for RJ71EIP91. ( MELSEC iQ-R EtherNet/IP Network Interface Module User's
Manual (Application))
• Class: 65H (101)
• Instance: I/O module mounting position value (the mounting position in order of proximity to the NZ2FT-EIP)
• Attribute: 75H (117)
How to check Process alarm
The following describes how to check Process alarm.
■Checking procedure
1.
Check that Unacknowledged process alarm (b5) of Status word ( Page 410 Status word) is set to 1.
2.
Set the following of Output data.
• Control word (b0) = 1 (Process alarm data)
• Diagnostic data control word = 0
3.
Check the I/O module that has detected Process alarm with Diagnostic data of Input data.
4.
Set the value of the mounting position of the I/O module that has detected Process alarm to Diagnostic data control word
of Output data.
5.
Check Process alarm data (4 bytes) of the specified I/O module with Diagnostic data of Input data. For the data
configuration of Process alarm data, refer to Process alarm data of each I/O module.
6.
When Unacknowledged process alarm (b5) is 1, there is an unacknowledged Process alarm, so repeat the procedure
from step 1.
