Introduction
This document describes the installation and operation of the Fieldbus Interface card. This card
permits a MICRO 4000 NET control system to communicate with a remote PLC or computer
through a fieldbus network.
Interface cards are available for the most popul
ar fieldbus protocols, including DeviceNet,
Profibus, ControlNet, Modbus Plus, Modbus/TCP, and Ethernet TCP/IP.
The fieldbus interface provides full control of operating mode, guide point position, servo gain,
and a
ctuator speed limit; and permits monitoring of actuator position, end-of-travel status, and
web position.
The fieldbus interface may be used in conjunction with other control inputs. These include the
front-p
anel switchpad, discrete isolated inputs, and remote operator station. When receiving
commands from multiple sources, the MICRO 4000 NET obeys the last command received.
The Fieldbus Interface card is compatible only
with the MICRO 4000 NET Controller. It is not
compatible with the MICRO 1000 Controller.
Installation
To install the fieldbus interface card in the MICRO 4000 NET controller, follow the steps below:
1. Field installation of the fieldbus inter
face card in the MICRO 4000 NET Controller:
f) Verify that the power source is off
and locked out.
g) Install the fieldbus interface card by pushing it firmly onto header P2 on the MICRO 4000
NET
controller assembly.
h) Secure the fieldbus interface card to the stand
offs with three #4-40, 0.25” long machine
screws and three #4 internal tooth star washers provided.
Note: If the
control system is ordered with the fieldbus interface card, these components
will be factory installed and tested prior to shipment.
2. Connections and settings:
a) Install the fieldbus interface cable through an available cord grip.
b) Connect the interface cable to the plug for the fieldbus interface card. Configure the card
with the co
rrect network address and baud rate (if required).
c) Insert the plug back into its mating con
nector on the interface card.
i) Make sure the circuit board is
free of metallic debris such as screws, lockwashers, and
wire strands.
d) If any of the cables have been removed, shorte
ned, or modified in any way, make sure
the connections agree with the appropriate connection diagram.
