Warning/Caution Notations
WARNING:
Personal injury/loss of life may occur if you
do not follow the procedures as specified.
CAUTION:
Equipment damage or loss of data may
occur if you do not follow the procedures
as specified.
Expected Installation Times
30 minutes.
Required Tools and Materials
• Flat-blade screwdriver (1/8-inch blade width).
• Wire strippers.
• Cabling and connectors. See the Connecting
the Driver to the Vendor’s Modbus Master or
Modbus Slave Device section.
CAUTION:
Always wear an electro-static discharge
wrist strap and discharge accumulated
static before touching field panel
components.
Prerequisites
• Driver hardware is installed according to its
respective installation instructions.
• FLN Termination blocks installed, if any.
• One AC power receptacle for each
communication interface adapter or device.
Depending on the type of installation, other
prerequisites may have to be completed.
Connecting the Driver to the
Vendor’s Modbus Master or
Modbus Slave Device
Follow these steps to connect the driver to the vendor
system:
1. Make cables per diagram in Figure 1, Figure 2,
or Figure 3.
2. If applicable, install the Trunk/RS-422 or Trunk
Interface II per diagram in Figure 1 or Figure 2.
3. Connect cables per diagram in Figure 1, Figure 2,
or Figure 3.
4. If applicable, plug in power supply for the
Trunk/RS-422 or Trunk Interface II per diagram
in Figure 1 or Figure 2.
For Modbus TCP and Modbus RTU
over Ethernet, use IEEE 802.3 standard
Ethernet connections and cabling to
complete your network infrastructure.
