6.6 Simulation Dip Switch
Simulation dip switch
A simulation parameter in the AO block is used to aid in system ‘debug’ if the process is not running.
A hardware dip switch is provided to enable or disable the simulate parameter. See Section 10.8 for
details on setting the simulation dip switch. (See Figure 10.1.)
6.7 Establishing Communications
Starting Communications
Once the Logix 3400IQ digital positioner is connected to the fieldbus network and powered up, the
user is ready to start communicating with the device.
The procedure in Table 6.3 outlines the steps to initiate communications with a Logix 3400IQ digital
positioner using the NI-FBUS Configurator.
Table 6.3 Starting Communications with Logix 3400IQ Digital Positioner
Step Action
1. Check that the fieldbus is powered up. Verify that the power supply is on and connected
with the proper polarity. See Table 4.2, Logix 3400IQ
Digital Positioner Power Requirements for proper
voltage levels.
2. Verify that the operator interface is loaded with
the NI-FBUS Configurator or other configuration
application. Start the application on the computer.
3. View the active devices connected to the network. Start the NI-FBUS fieldbus driver and Configurator.
NOTE: Network guidelines as out lined in AG-181
have been followed
4. Access the Logix 3400IQ digital positioner’s blocks
and parameters. Start the NI-FBUS Configurator application.
Tag Name Assignments
If device or block tags have not been assigned to a device, the NI-FBUS Configurator will automati-
cally assign a default device tag name. This is done so that the devices are visible on the network. The
user can then change tag names according to the process requirements.
6.8 Making Initial Checks
Identifying the Logix 3400 Digital Positioner
Before proceeding, verify the following to make sure that the user is communicating with the correct
Logix 3400IQ digital positioner:
Device type = 0 x 0202
Device ID = 464C530202-FLS-LX3400-00nnnnnnnn
Device tag, (tag description of the Logix 3400IQ digital positioner)
Firmware revision level (revision level of the firmware elements)
Table 6.4 lists the block parameters for quickly identifying the Logix 3400IQ digital positioner.
