1.Important Notes
Solid state equipment has operational characteristics differing from those of electromechanical equipment.
Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls describes some important
differences between solid state equipment and hard-wired electromechanical devices.
Because of this difference, and also because of the wide variety of uses for solid state equipment, all persons
responsible for applying this equipment must satisfy themselves that each intended application of this equipment is
acceptable.
In no event will CREVIS be responsible or liable for indirect or consequential damages resulting from the use or
application of this equipment.
The examples and diagrams in this manual are included solely for illustrative purposes. Because of the many variables
and requirements associated with any particular installation, CREVIS cannot assume responsibility or liability for actual
use based on the examples and diagrams.
If you don’t follow the directions, it could cause a personal injury, damage to the equipment or explosion
Do not assemble the products and wire with power applied to the system. Else it may cause an electric arc, which
can result into unexpected and potentially dangerous action by field devices. Arching is explosion risk in
hazardous locations. Be sure that the area is non-hazardous or remove system power appropriately before
assembling or wiring the modules.
Do not touch any terminal blocks or IO modules when system is running. Else it may cause the unit to an electric
shock or malfunction.
Keep away from the strange metallic materials not related to the unit and wiring works should be controlled by the
electric expert engineer. Else it may cause the unit to a fire, electric shock or malfunction.
If you disobey the instructions, there may be possibility of personal injury, damage to equipment or
explosion. Please follow below Instructions.
Check the rated voltage and terminal array before wiring. Avoid the circumstances over 50℃ of temperature.
Avoid placing it directly in the sunlight.
Avoid the place under circumstances over 85% of humidity.
Do not place Modules near by the inflammable material. Else it may cause a fire.
Do not permit any vibration approaching it directly.
Go through module specification carefully, ensure inputs, output connections are made with the specifications. Use
standard cables for wiring.
Use Product under pollution degree 2 environment.
Warning!
Caution!

4.Mechanical Setup
4.1. Total Expansion
The number of the module assembly that can be connected is 32. So the maximum length is 426mm Exception.
ST-2748 is excepted to calculate maximum length because that is double width module.
4.2. Plugging and Removal of the Components.
Before work is done on the components, the voltage supply must be turned
off.
As above figure in order to safeguard the FnIO module from jamming, it should be fixed onto the DIN rail with locking
level. To do so, fold on the upper of the locking lever.
To pull out the FnIO module, unfold the locking lever as below figure.

4.3. Internal FnBus/Field Power Contacts
Communication between the NA series and the expansion module as well as system / field power supply of the bus
modules is carried out via the internal bus. It is comprised of 6 data pin and 2 field power pin.
Do not touch data and field power pins in order to avoid soiling and damage
by ESD noise.

5.MODBUS Electrical Interface
5.1. FnBus System
• Network Adapter Module
The Network Adapter Module forms the link between the field bus and the field devices with the Expansion
Modules.
The connection to different field bus systems can be established by each of the corresponding Network Adapter
Module, e.g. for SyncNet, PROFIBUS, CANopen, DeviceNet, Ethernet/IP, CC-Link, MODBUS/Serial,
MODBUS/TCP etc.

MODBUS/TCP IP Address Setup
IP-Address Setup using ARP
A way to change the adapter IP address could be applied using such as Command Windows (only applicable same
subnet). This new IP address remains during power cycle.
DOS Prompt
>ping 192.168.123.236 //current IP address
>arp -a //view Ethernet physical address
>arp -d 192.168.123.236 //delete arp table
>arp -s 192.168.123.237 00-14-F7-00-00-00 //assign static arp table with new IP address
//”00-14-F7-00-00-00” is Ethernet Address
(See Adapter Label)
>ping -n 1 –l 741 192.168.123.237 //assign new IP address
>arp -d * //clear all arp table
>ping 192.168.123.237 //check response of adapter new IP address
After IP-Address setup using ARP.
IP Address = 192.168.123.237
Subnet Mask = 255.255.255.0
Gateway = 192.168.123.254
Note!
The default IP adress are: 192.168.123.1

IP-Address Setup using BOOTP
If the adapter BOOTP enabled, the adapter sends BOOTP request message of 20 times every 5sec.
The following is an example of adapter IP-Address setup that can be used with a third party BOOTP server.
Rockwell Automation’ s BOOTP server
