Soft Bool and Soft Int Registers in the Database
The database provides 1000 1-bit (Boolean) registers and 2100
word (Integer) registers that may be accessed both by a logic
program and by AnaWin3 or third-party software.
Table 5.44 lists the parameter number, range, and first and
last Modbus addresses for each Soft Bool and Soft Int
parameter.
Table 5.44 Soft Bool and Soft Int Parameters
Accessing Soft Bool and Soft Int Registers with Modbus
The Boolean and Integer registers are accessed by Modbus
address. Table 5.46 on page 206 lists first and last Modbus
addresses for the Boolean and Integer registers. Use these
addresses when accessing Boolean and Integer registers with
third-party software or operator interface terminals.
Accessing Soft Bool and Soft Int Registers with LogicPro
When a logic program variable accesses a Boolean or Integer
register, the database offset is used in conjunction with the
LogicPro Soft_Bool or Soft_Int I/O driver. The LogicPro IO
Physical Address is constructed from the database offset only.
See the LogicPro User’s Guide for specific instructions on
addressing Boolean and Integer registers. See Table 5.46 on
page 206 for the LogicPro IO Physical Address of each register.
Soft Bool and Soft Int Registers
Table 5.46 lists the LogicPro IO Physical Address ranges,
database offsets and first and last Modbus addresses for the
Boolean and integer registers. These values are used when
accessing Boolean and Integer registers with third-party
software, operator interface terminals or LogicPro programs.
