3. Creating of PLC Ladder
You must create PLC Ladder routime for communication setting in order to communicate with your computer and FUJI ETHERNET module.
a) Please transfer parameters data to FFU170B or NC1L-ET1 ethernet module from CPU.
This parameters should be transferred from registers to CPU to File No.0 in FFU170B or NC1L-ET1 module with a MSGT instruction.
b) Initialize the FFU170B or NC1L-ET1 ethernnet module.
Module initialization should be 'On' B70 memory area of PLC. (When ethernet module installed slot 1)
initialization success : B30 = On, initialization failure : B30 = Off. (When FFU170B or NC1L-ET1 ethernet module installed slot 1)
c) Please set Open Connection.
Please set to On Open Connection request relay(Connection 1 ~ 8 : B58 ~ B5F).
The Open Connection is completed, B18 (Connection 1) ~ B1F (Connection 8) relay set to On.(When FFU170B or NC1L-ET1 ethernet module installed slot 1)
* Example of Ladder program)
Setting value) protocol : TCP, service port number : computer(PC) - 2000, PLC - 2000
IP Address: computer(PC) - 192.168.0.15, PLC - 192.168.0.2
TCP transmission timeout value : 300 (30 second)
Max TCP end time value : 600 (60 second)
Response monitor timer value : 300 (30 second)
Server FTP command monitor timer value : 3000 (300 second)
Client FTP data connection monitor timer value : 30 (3 second)
Subnet mask : 255.255.255.0
Example of Ladder program)
<Figure 1> is example of Ladder program for TCP connection.

4. The method of TCP/IP communication speed problem
When you communicate with Fuji PLC after creating the PLC Ladder program such as chapter 3, one send/receive packet data take aboub 0.5 second or more.
You can fix this proble as follows.
Open 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Afd\Parameters\IgnorePushbitOnReceives' at Registry of Windows.
Please set this 'DWORD' value to '1'. (previous value = 0)
Setting example of Registry problem)
Run 'regedit' at ' ¡®Start|Execution¡¯ of Windows, then open window 'Registry editor' such as <Figure 2>.
Normally 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Afd' key made by Ladder program, but part of 'Parameters\IgnorePushbitOnReceives' key will be don't exist.
So you have to creat this key.

Note) When you using UDP/IP for FUJI MICREX-F ENET, generally don't happen registry problem.
