Hardware revisions and unit versions are used to manage the hardware and software in NX-series
Units and EtherCAT slaves. The hardware revision or unit version is updated each time there is a
change in hardware or software specifications. Even when two Units or EtherCAT slaves have the
same model number, they will have functional or performance differences if they have different hard-
ware revisions or unit versions.

Checking Versions

You can check versions on the ID information indications or with the Sysmac Studio.

Overview of FINS

FINS is a command system for the message service that can be used commonly in OMRON network.
The FINS command system allows to read sent and received data, status etc. between a host comput-
er and an NX-series CPU Unit, and between an NX-series CPU Unit and an OMRON CPU Unit.
FINS provides server and client functions.
For details about the FINS frame format, refer to the SYSMAC CS/CJ/CP/NSJ-series Communications
Commands Reference Manual (Cat. No. W342).

Server Function of FINS

This function allows to receive FIN commands from external devices such as host computers or OM-
RON CPU Units and then to execute requested services.

Client Function of FINS

This function allows NX102 CPU Units to send and receive data to/from OMRON Units which is pro-
vided with Server Function of FINS.

FINS Routing Table Setting
The routing table is a table that is used to find the communication path of the FINS message when the
FINS communication service is in use.
The routing table consists of two types of tables: local network table and relay network table.
Here are the cases, where the setting of FINS routing table is required.
• When the FINS routing table is already set at one or more nodes in the same network and the FINS
message communications are performed, the local network table setting is required.
For details, refer to A-1 Difference Between CS/CJ-series and NX-series in FINS Routing on page
A - 2.
• When the FINS command is issued over the level of the FINS network, the relay network table set-
ting is required.
To set the FINS routing table, select Configurations and Setup - Controller Setup - Operation
Settings - FINS Settings from the Multiview Explorer of the Sysmac Studio.

FINS Write Protection Function

When data is written into the CPU Unit using the FINS command, this data writing can be disabled so
that the data is not written into the memory of the CPU Unit.
This function is called the FINS write protection function.
The models that support the FINS write protection function are NX701-££20 and NX102-££££.
To set whether to use the write protection function select Configurations and Setup - Controller
Setup - Operation Settings - FINS Settings - Security Settings from the Multiview Explorer of the

Even when the FINS write protection function is enabled, the data reading from the CPU Unit is still
possible.

Overview of Client Function

FINS communication instructions is a set of instructions, which allows to control data send/receive,
mode change etc. as required, for various types of units such as CPU Units and CPU Special Units on
the network or CPU Rack.
These instructions are executed over multiple cycles and perform the communication non-synchron-
ized with the cycle.

• During execution of this instruction, set Option.Retry to a value other than 0 by considering the case
when the send message or response is lost due to noise that occurs during communication. If no
response is returned within Option.TimeOut, it is recommended to retry the process.
• When this instruction is written in the ST program, make sure that the instruction is executed for
each task period during execution of this instruction. If this instruction is not executed every task pe-
riod, the normal process may not be performed.
• This instruction cannot be used on the event task. An error occurs during compiling.

Precautions for Correct Use
• This instruction can be executed only when there is an available port. Therefore, use the system-
defined variable _Port_isAvailable
execution condition for the instruction.
• The command is not sent if the value of CmdSize is 0. When the instruction is executed, the value of
Done changes to TRUE.
• During execution of this instruction, set Option.Retry to a value other than 0 by considering the case
when the send message or response is lost due to noise that occurs during communication. If no
response is returned within Option.TimeOut, it is recommended to retry the process.
• When this instruction is written in the ST program, make sure that the instruction is executed for
each task period during execution of this instruction. If this instruction is not executed every task pe-
riod, the normal process may not be performed.
• This instruction cannot be used on the event task. An error occurs during compiling.
• An error occurs in the following cases. Error will change to TRUE.
a) A member of DstNetAdr is outside of its range.
b) CmdSize is outside of its range.
c) The value of CmdSize exceeds the size of CmdDat[].
d) A member of Option is outside of its range.
e) The response size exceeds the size of RespDat[].
f) The value of _Port_isAvailable is FALSE.
g) Communications fail.
Data type
USINT This is the number of ports that are currently used.

Difference Between CS/CJ-series and NX-series in FINS Routing
The FINS routing specification settings in the NX-series CPU Units differ from those in the CS/CJ-ser-
ies CPU Units by the following points:
• Communication when 0 is specified for the destination network address
• Operation of the routing table during Clear All Memory operation.
Communication When 0 Is Specified for the Destination Network Address
The communication may vary depending on the CPU Unit as described below.
CPU Unit Operation
NX-series Routing of the network of the built-in EtherNet/IP port.
CS/CJ-series Routing of the network of the Communications Unit that has the smallest unit number among the
installed CS/CJ-series Special Units.

Additional Information
For the CS/CJ-series CPU Units, the FINS command is issued to the network of the FINS net­work Communications Unit that has the smallest unit number.
A-1 Difference Between CS/CJ-series and NX-series in FINS Routing
*1. When the FINS command specified with network address 0 and node address n is issued to a CPU
Unit with no local network table specified, the FINS command is issued to the FINS network of the lowest unit number.
When the opposite unit is the CS/CJ-series CPU Unit and 0 is specified for the destination net­work address, the communication may or may not be possible as described below.
Communication is possible when network number 0 is specified
• When only one FINS network Communications Unit is connected to the opposite CS/CJ-ser­ies CPU Unit.
• When multiple FINS network Communications Units are connected to the opposite CS/CJ­series CPU Units, and the FINS network Communications Unit is connected to the CS/CJ­series CPU Unit that has the smallest unit number.
In this case, the routing table setting is not required for the NX-series CPU Unit.
A
A-1-1 Communication When 0 Is Specified for the Destination Network Address

Communication is not possible when network number 0 is specified
• When multiple FINS network Communications Units are connected to the opposite CS/CJ­series CPU Units, and the FINS network Communication Unit is connected to a CS/CJ-series CPU Unit other than the unit that has the smallest unit number
. In this case, routing table setting is required for both the NX-series CPU Unit and the CS/CJ­series CPU Unit.
