For example, the parameter number for setpoint, found in
, is 95. The database offset for channel
parameters is channel number. So using the Database IO
Driver supplied with
LogicPro
the IO Physical Address for the
setpoint of channel 23 is 95.23.
Refer to the LogicPro User’s Guide for detailed instructions on
using the IO Drivers and creating logic programs. Refer to this
chapter of this manual for specific LogicPro IO Physical
Addresses, and parameter numbers.
Analog and Counter Input Parameters in the
Database
Analog input parameters determine how measurements of
signals from sensors attached to modules are read and scaled
into engineering units for use by closed-loop control channels,
monitor channels and logic programs. These parameters can be
read and set by Modbus devices and logic programs.
Accessing Analog and Counter Input Parameters with
Modbus
To access analog and counter input parameters, use the
database offset as the Modbus address offset. See
database offsets and Modbus addresses corresponding to the
analog and counter inputs.
lists first and last Modbus addresses for
each input parameter. Use these addresses when accessing
analog or counter input parameters with third-party software
or operator interface terminals.
Accessing Analog and Counter Input Parameters with
LogicPro
To access counts, frequencies, and analog input values
measured by the modules, use the appropriate IO Driver in
LogicPro
. There are separate drivers for each type of module.
The driver requires an IO Physical Address to determine which
analog input to read on the module. See
through
LogicPro
IO
Physical Address.
The
LogicPro
IO Physical Addresses are listed by input
according to the default Input names as seen in
AnaWin3
. To
correlate the
AnaWin3
name with the hardware connection see
Table 2.10 on page 39, Table 2.12 on page 47, Table 2.15 on
page 56, Table 2.16 on page 56, and Table 2.19 on page 60
When a logic program variable accesses an analog input
parameter, the parameter number (#) and the Database Offset
are used in conjunction with
LogicPro’s
Database IO Driver.
