■B000H to B7FFH (45056 to 47103) Process alarms
For Process alarms of each module, 64 bytes (32 register areas) are reserved. For example, if the mounting position of the
module is the third in order of proximity to the NZ2FT-MT, the third module starts at address B040H and 4 bytes are stored.
If there is a bit that is turned on in register address 101CH to 101FH (4124 to 4127) Collective process alarm message for I/O
modules, Process alarm is checked by reading the corresponding Process alarms. After reading Process alarms, the bits of
the corresponding I/O module with register addresses 101CH to 101FH are turned off.
When all Process alarms are read, the bits of all I/O modules with register addresses 101CH to 101FH are turned off.
For details on how to read Process alarm data and the data structure, refer to the following.

■C000H to FFFFH (49152 to 65535) Module parameters
The parameter data of 256 register areas is allocated for each module.
For example, if the mounting position of the module is the third in order of proximity to the NZ2FT-MT, the third module starts
at register address C200H.
The parameters of each module can be set from the Web server or master station.
One register is assigned to each parameter, and two consecutive registers are assigned to a 32-bit length parameter (such as
the NZ2FTS-D62P2 parameter "End value").
For example, in the third module in order of mounting position proximity to the NZ2FT-MT, the eighth parameter is C207H
(provided that there is no 32-bit length parameter).
When setting 32-bit length parameters, pay attention to the send method (Data format) of communication data. ( Page
