Analog Output Parameters in the Database
Analog Output Value is the only analog output parameter. The
analog output registers determine the levels of signals output
by the analog outputs on the Encoder In Analog Out modules.
Accessing Analog Outputs with Modbus
The Modbus address offsets for Analog Output Value correspond
to the analog output. See Table 5.42 on page 203 and Table 5.43
on page 204 for a list of the analog outputs and the
corresponding Modbus addresses.
The table lists first and last Modbus addresses for each module
with analog outputs. Use these addresses when accessing
analog output values with third-party software or operator
interface terminals.
Accessing Analog Outputs with LogicPro
When a logic program variable accesses an Analog Output Value,
the LogicPro IO Physical Address is used in conjunction with
the LogicPro IO driver for the corresponding module type.
The LogicPro IO Physical Addresses are listed by output
according to the default output names as seen in AnaWin3. To
correlate the AnaWin3 name with the hardware connection see
Table 2.20 on page 60 and Table 2.22 on page 67.
See the LogicPro User’s Guide for specific instructions on
addressing analog outputs. See Table 5.42 and Table 5.43 for a
list of the LogicPro IO Physical Addresses corresponding to the
analog outputs.
Analog Outputs and Modbus Addresses
Table 5.42 and Table 5.43 list the LogicPro I/O physical
address and Modbus address for each Analog Output Value
corresponding to the modules, module addresses and module
output numbers of each analog output.
