Ethernet Setup for the S2T  
Ethernet communications with the S2T CPU is done through the GEN651A Ethernet module.  
Prior to using this module, it must be configured using the EtherSetup_E setup software. The  
EtherSetup_E software is used to configure the network parameters (IP Address, Subnet  
Mask, and Multicast Addresses) in the GEN651A Ethernet module. When all the following  
setup steps described below are completed, Ethernet connection to the S2T through the  
GEN651A Ethernet module will be possible. There are two methods of connection:  
T-PDS (Toshiba Program Development Software). UDP/IP Socket Interface.  
Setup GEN651 Ethernet Module  
This module must be setup 1st before either of the connections methods are possible.  
1, Install the EtherSetup_E software on an MS Windows computer. See the installation  
instructions in the User’s Guide for the Ethernet Module Parameter Setting Tool, 6F8C1103.  
2, Set the network parameters in the GEN651A module.  
2.1 Set the DIP switches on the front of the EN6651A to enable setting the network  
parameters from the EtherSet_E. Set DIP Switches 7 & 8 to ON (Note: 7 & 8 are the top  
two switches).  
2.2 Mount the EN651A on the S2T rack, then turn on power.  
2.3 Connect PC and EN6651A with the V-Tool cable (standard RS232C cross cable).  
2.4 Run the EtherSet_E software on the PC.  
2.5 Click the Read button on the EtherSetup_E screen. The current settings are read from  
the GEN651A and are displayed on the screen.  
On reading a module for the  
1st time, settings will appear as  
shown to the left.  
 
Computer Ethernet Card Setup: The computer’s Ethernet card must be setup first. Go to  
the Control Panel and double click on Network Connections. Find the Ethernet card, alternate  
click on it and then click on Properties.  
Note that the IP Address and Subnet Mast must be the same as set in T-PDS & the GEN651A  
(the last digit of the IP Address must be different however, it cannot be .1  
The address  
of the GEN651A module is 172. 16.64.1 ). Click OK. In case of difficulty setting up the  
computer Ethernet card, contact the company MIS/IT Department.

T-PDS Setup: In T-PDS under the Option Menu, select Communications. Set as follows:  
Using T-PDS, set the following in special register SW63:  
This setting can also be made  
in the ladder logic with a MOV  
instruction.  
This completes the T-PDS setup. T-PDS can now be connected to the S2E via Ethernet  
through the GEN651A Ethernet module.  
Note: If an attempt is made to assign an IP address in T-PDS before the computer’s Ethernet  
card is assigned a corresponding IP address, then T-PDS will return a Win Socket error.

UDP/IP Socket Interface:  
To use UDP/IP transmission, it is necessary to create a small program in the S2T. The  
program will utilize the SEND and RECV instructions. The general procedure is as follows:  
1. Execute UDP socket open: The Specified Port number must be different from the Port  
number for T-PDS connection. If the Port number for T-PDS is 2000, the Port number for  
UDP socket must be other than 2000 to 2002. It is recommended that 2 UDP sockets be  
opened. One for data send and one for data receive respectively.  
2. Execute UDP send and/or UDP receive to exchange data via Ethernet.  
3. UDP socket close.  
The instruction information on these functions is shown as follows.  
UDP Socket Open: SEND instruction is used. [ A SEND B ].  
A: H3100 (fixed)  
B: Result status  
A+1: UDP open command (H0031)  
A+2: Socket number (1 to 12)  
A+3: UDP Port number  
B+1: Error code  
Sample Program  
12544 = H3100  
49 = H0031  
Socket number =1  
Port number = 4000  
When R0620 is set to ON, the UDP open operation is executed. When the operation is finished  
R0620 is reset to OFF automatically.

UDP Send: SEND instruction is used. [ A SEND B ]▬  
A: H3100 (fixed)  
B: Result status  
A+1: UDP send command (H0032)  
A+2: Socket number (1 to 12)  
A+3: Receiver IP address (note 1)  
A+4: Ditto  
B+1: Error code  
A+5: Receiver Port number  
A+6: Transmit data word size (1 to 1000)  
A+7: Source data table register type (note 2)  
A+8: Source data table register starting address  
Note 1  
If receiver IP address is 192.0.0.5 (HC0.0.0.5), set as follows.  
A+3 = H0005  
A+4 = HC000  
Note 2  
RW register = 3  
D register = 4  
Sample Program  
12544 = H3100  
50 = H0032  
Socket number = 1  
Receiver IP address = 192.0.0.5 (-16384 = HC000)  
Receiver Port number = 4000  
Transmit ward size = 200  
Source data table is D1000 and after  
When R0622 is set to ON, 200 data words D1000 to D1199 are transmitted to the destination  
(IP address = 192.0.0.5, Port number = 4000). When the operation is finished, R0622 is reset  
to OFF automatically.

A+2: Socket number (1 to 12)  
A+3: Sender IP address (note 1)  
A+4: Ditto  
A+5: Sender Port number  
A+6: Receive data word size (1 to 1000)  
A+7: Destination data table register type (note 2)  
A+8: Destination data table register starting address  
A+9: Timeout setting (0.1s units, see note 3)  
Note 1: If sender IP address is 192.0.0.5 (HC0.0.0.5), set as follows.  
A+3 = H0005  
A+4 = HC000  
For broadcast receiving, set 0.0.0.0.  
Note 2:  
RW register = 3  
D register = 4  
Note 3: If A+9 = 0, there is no timeout.  
Sample program  
12544 = H3100  
51 = H0033  
Socket number = 2  
Sender IP address = 192.0.0.5 (-16384 = HC000)  
Sender Port number = 5000  
Receive word size = 100  
Destination data table is D2000 and after, no timeout setting  
Page 7  
 
When R0621 is set to ON, 100 data words are received from the sender (IP address =  
192.0.0.5, Port number = 5000) and are stored in D2000 to D2099. When the operation is  
finished, R0621 is reset to OFF automatically.

reset to OFF automatically.
