The SPX Pro-V2 includes a trap receiver supporting both v1 and v2c
traps. The template driven trap receiver provides multiple algorithms for
recognizing traps, and can easily place trap information into holding registers
for Modbus access. If more complex treatment of trap information
is needed, such as character string interpretation, Script Basic can be used
to process traps and place resulting data into Modbus registers.
The SPX Pro-V2 allows the user to create the Modbus register set. The
“registers” can be 16, 32, or 64 bit (with any registers greater than 16 bits
being automatically treated as a series of Modbus registers). Holding registers
can be integer, unsigned integer, or IEEE 754 fl oating point, single
or double precision. The SPX Pro-V2 also supports character strings as a
series of registers having two ASCII characters per register. These character
registers can be read and written from Script Basic as a single string
variable. Although all local registers are allocated as holding registers,
they can also be accessed as input registers, discrete inputs, or coils.
