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.
