Access to Process Data

The I/O data of the I/O module is stored in Process data of the NZ2FT-PN and data communication is performed with the
RJ71PN92.

Data configuration

For each IO device, Process data and Status word are placed in Output data and Input data.
Status word is data indicating the status of the NZ2FT-PN. ( Page 223 Confirmation by status information (Status word))

Output data
• In Process data (Output) of each I/O device ID, Process data of each I/O module is arranged in order of mounting position
proximity to the NZ2FT-PN and with no clearance.
• The size of Process data (Output) depends on the type and number of I/O modules. ( Page 212 Data width used by the
I/O module)
Input data
• Whether to add Status word to Input data is set in advance with GX Configurator-PN. ( Page 201 Device Library)
• In Input data of each I/O device ID, Status word is placed at the start followed by Process data (Input) of each I/O module,
in order of mounting position proximity to the NZ2FT-PN and with no clearance.
• The size of Process data (Input) depends on the type and number of I/O modules. ( Page 212 Data width used by the
I/O module)
• Process data can 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.
