Introduction
The FR-2053TA/FR-2053HTA module provides a 16-channel isolated sink/source
digital output in the FRnet. The “-T” denotes the screw terminal connector,
allowing users to connect to the DO signals on the module directly. The I/O
data transmission is controlled by the FRnet control chip which was developed
by ICP DAS. It was designed to provide for deterministic high-speed network
communication. The communication mechanism is dominated by the token stream,
which is generated by the network manager located at a specific node (SA0).
This manager provides for fixed scan-time and I/O synchronization capability
without the need of any special communication protocol. Furthermore, special
anti-noise circuitry has also been considered and built into the FRnet control
chip to ensure communication reliability. This distributive digital output
module must be connected to another module or a host controller with a network
manager built in.
However, the effectiveness of the FRnet connection depends on and is then
ensured when the correct hardware configurations for the sender address (SA)
and receiver address (RA) on the host controller and the remote module in the
network have been installed properly. In general, the operating principle is
structured by the strategy of delivering the 16-bit data from the specified
sender address (SAn) to the corresponding receiver address (RAn) via the
broadcasting method controlled by the token stream of the network manager,
SA0. Based on this algorithm, there are some general rules that need to be
followed:
- The sender’s address needs to be unique in order to avoid any communication collisions.
- Each of FRnet needs at least one network manager defined as SA0. It plays an important role of producing the token stream in the network.
- The baud rates of the controller and the remote modules need to be the same as on the front.
- The communication method is controlled by delivering the data of the specified sender address (SA) to the corresponding receiver address (RA) in the sequence of token 0 to N cyclically, as depicted below.
- Due to the broadcasting algorithm adopted, the receiver address is not required to be unique. Therefore, it is easy to build a data delivery from one node (16-bit data) to a multi-node.
An example of the FRnet application structure for delivering data from the
specified sender address (SAn) to the corresponding receiver address (RAn) by
a 4-wire inter module cable, including a 2-wire power supply cable, is shown
in the figure below.
Features
- The Token stream is used to activate data transmission from the specified SA node to the corresponding RA nodes.
- The Network Manager is defined as SA0. Each of the FRnet must have SA0 because it issues the Token stream into the network.
- The Token stream is produced cyclically by the hardware system (SA0) at the fixed time interval, see Figure 1.1. Therefore, the FRnet system can provide for both Isochronous and Deterministic functionalities.
- It can provide data transmission from one node (16-bit) to one node or from one node to multiple nodes at the same time because FRnet uses the principle of delivering the data from the sender address to the receiver address. Therefore, the sender address must be unique, but the receiver address can be different or the same in the network.
- The FRnet system can easily be extended by adding new modules to the network according to the FRnet principle.
- Device Inter-communication: A single device can talk to other devices by setting appropriate SA and RA node configurations.
- No software overhead: All data transmissions are performed automatically via the FRnet control chip. Therefore, there is no need for the CPU or firmware to process transmission protocols.
- It only needs simple RS-485 wiring.
- The DIN-Rail mounting is provided.

- ON(END) : 120R terminating resistor Enable
In additional to these connectors, there is also one switch on the side of the module which can decide to use the internal terminal resistor on the network or not. If you switch it on, it means that the module will provide the terminal resistor on the network. Note that each network needs two modules to be on, which are usually the first and last module on the network.

Address Setting
Receiver address setting :
Since the FR-2053TA is a digital input module, the module can only configure
the sender address (SA) by the dip-switch, as shown in the following figure.
This means that the FR-2053TA can only transmit 16-bit data of the digital
input circuit to the node of the corresponding receiver address. The
configuration method is depicted in the following figure: 
FRnet Application Structure
Within conventional communication methods in the control network system, the
master (host) controller (CPU) must send a command with data to the slave
module. Then it must wait for confirmation from the slave’s response, which is
based on a complicated and fixed transmission protocol. If there are many
devices on the network, all the data transmission within the network must be
controlled by the master (host) controller (CPU). Therefore, the performance
of communication efficiency between the host controller and each of the
devices will usually be deteriorated when more and more devices are added in.
In contrast to this solution, our FRnet provides innovative data transmission
method which adopts the hardware FRnet control chip to do communication
broadcasting and gets rid of the software transmission protocol. It is easy to
set up a reliable network merely by hardware setting both the “Sender Address”
and “Receiver Address” of all the modules.
There are two FRnet host controllers provided by ICPDAS products, the
FRB-100/200/200U and the 7188EF-016. The first one is a PCI interface add-on
card, and the other one is an Ethernet embedded controller. Two possible
application configurations are demonstrated as follows.
Case 1: If the PC-based FRB-200(U)/100 is used as the host controller
Case 2: If the embedded controller i-7188EF-016 is used as the host controller
