Access To Process Data; Data Width Used By The I/O Module - Mitsubishi Electric NZ2FTGN User Manual

12.7

Access to Process Data

I/O data of the I/O module is stored in Process data, and data communication with the buffer memory of the RJ71EIP91 is
performed.
Data configuration
Process data consists of Input data and Output data.
In NZ2FT-EIP, Process data is included in each of Input data and Output data.
Item Data size
Input data Variable length
(byte)
Output data Variable length
(byte)
• Process data can also be checked from the Web server. ( Page 72 "Process data").
• The communication data format can be changed to little-endian or big-endian by setting the parameter.

12.7 Access to Process Data
Description
Input data of the I/O modules connected to the NZ2FT-EIP.
The data size varies depending on the connected I/O modules and the number of them. ( Page 392 Data width used by
the I/O module)
A Status word that indicates the status information of the NZ2FT-EIP and Diagnostic data stored by Process alarm data of the
I/O modules are assigned before and after Process data. ( Page 394 Input data)
Output data of the I/O modules connected to the NZ2FT-EIP.
The data size varies depending on the connected I/O modules and the number of them. ( Page 392 Data width used by
the I/O module)
Control word and Diagnostic data control word used when Process alarm data of the I/O modules is read from the NZ2FT-
EIP are assigned before and after Process data. ( Page 394 Output data)
