!WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PLC System to the above-mentioned appli- cations.
Page 22: Operating Environment Precautions
• Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. !Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual. The loose screws may result in burning or malfunction.
Page 23 Application Precautions • Always turn OFF the power supply to the CPU Unit, Slaves, and Commu- nications Units before attempting any of the following. Not turning OFF the power supply may result in malfunction or electric shock. • Mounting or dismounting I/O Units, CPU Units, Memory Packs, or Master Units.
Page 24: Conformance To Ec Directives
• Always lay communications cable inside ducts. • Use appropriate communications cables. • Before touching a Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up. Not doing so may result in malfunc- tion or damage.

Another feature of FINS/UDP is that it can be used for broad- casting. On the other hand, with FINS/UDP it is necessary to provide measures, such as retries, for handling communications errors.

1-5-1 FINS Communications Service Basic Functions FINS commands can be sent to or received from other PLCs or computers on the same Ethernet network by executing SEND(090), RECV(098), or CMND(490) instructions in the ladder diagram program. This enables various control operations such as the reading and writing of I/O memory between PLCs, mode changes, and file memory operations.
Page 43: Socket Services
Section 1-5 Overview of Communications Functions • Even if the IP address and UDP port number of the host computer (a DHCP client computer) are changed, it is still possible for the host com- puter to send FINS commands to PLCs on the Ethernet network and to receive responses.
Page 44 Overview of Communications Functions Executing CMND(490) Another way to use socket services is to request a UDP or TCP socket ser- vice by sending a FINS command to the Ethernet Unit by executing CMND(490) from the CPU Unit. When the Ethernet Unit receives the socket service request, it returns a response to the CPU Unit to confirm that it received the request, and then begins the requested processing.

When using this method, always leave the local IP address in the CPU Bus Unit Setup Area set to the default value of 0.0.0.0 If the CPU Bus Unit Setup Area contains any other value, any setting made in the allocated DM words will be overwritten with it.
Page 56: Switch Settings
Note (1) Turn OFF the power supply before setting the unit number. (2) If the unit number is being set for the first time or changed, then I/O tables must be created for the PLC. (3) With CS-series and CJ-series PLCs, words are automatically allocated in the CIO Area and DM Area according to the unit numbers that are set.

Precautions Precautions on Laying Twisted-pair Cable Basic Precautions • Press the cable connector in firmly until it locks into place at both the hub and the Ethernet Unit. • After laying the twisted-pair cable, check the connection with a 10Base-T cable tester.
Page 61 • Connect the hubs using special cables or special racks. • Normally there is no limit to the number of hubs in a stack, and each stack is treated as one hub. Some hubs, however, are limited in the number of hubs per stack.
Page 62: Using Contact Outputs (Common To All Units)
Using Contact Outputs (Common to All Units) Communications errors can occur when Contact Output Units are mounted to the same Rack or connected to the same PLC as an Ethernet Unit due to noise generated by the contact outputs. Use one or more of the following measures when installing Contact Output Units and Ethernet Units on the same Rack.

!Caution Allow enough space for the bending radius of the twisted-pair cable as shown in below. 35 mm 1,2,3... 1. Lay the twisted-pair cable. 2. Connect the cable to the hub. Be sure to press in the cable until it locks into place. Request cable installation from a qualified professional.
Page 64: Creating I/O Tables
2-6-1 I/O Table Overview I/O tables are used to identify Units mounted to the PLC, and to allocate I/O to them. With CS-series and CJ-series PLCs, whenever there is a change to the Unit configuration it is necessary to create I/O tables and register the Units to the CPU Unit.
Page 65: Procedure For Creating I/O Tables
Use the following procedure to create the I/O tables. Note With the CJ Series, it is necessary to create I/O tables only when I/O alloca- tion is performed by the user. With the CS Series, it is always necessary to create I/O tables.

Therefore, when using the FINS/TCP method, FINS/TCP headers must be added at the beginning of FINS frames in order to serve as FINS frame delimiters. The length of the data in the following FINS frame is stored in the header, allowing the frame to be separated out by the remote node.

Page 168: Writing Programs
CPU Units have eight communications ports. Only one instruction can be executed at any given port at one time, however, so the program must not overlap the use of any of the ports. A program example is provided below.
Page 169 Bit 1: Port 1 Bit 0: Port 0 Note With CS/CJ-series PLCs, communications ports 0 to 7 are also used for exe- cuting the PCMR(260) (PROTOCOL MACRO) instruction, so these flags are used in common for SEND(090), RECV(098), CMND(490), and PCMR(260).
Page 170 Completion Codes execution is reflected as a communications port completion code, in one word (two bytes) of data as shown in the following table. (The value is 0000 during instruction execution.) The recorded status is saved until execution of the next instruction.

If the time is read out from a Programming Device, the time will be shown as all ze- ros in the year 2000.

Page 263 Network memory consists of 248K bytes of memory divided into short and long buffers. The use of short and long buffers is determined by the status of the various services when the Ethernet Unit is running. The capacity of all buffers cannot be used due to limits in the mounted memory capacity. The status of the short and long buffers can be accessed by execution the FINS command MEMORY STATUS READ (2763).
