SECTION 1 Features and System Configuration This section provides basic information on Controller Link Networks, and will give the reader an overview of what Controller Link Networks can do and how best to use them. Overview ........... . . 1-1-1 What Is the Controller Link? .
Page 18: Overview
What Is the Controller Link? The Controller Link is an FA network that can send and receive large data packets flexibly and easily among the OMRON C200HX/HG/HE Programma- ble Controllers (PCs), CS-series PCs, CJ-series PCs, CVM1 PCs, CV-series PCs, CQM1H-series PCs, and IBM PC/AT or compatible computers.
Page 19 CMND The CMND instruction issues a command to read or write data of other nodes, control, or read error logs. With the Controller LInk Unit, OMRON’s command protocol called “FINS commands” is used.
Page 20: Features
Overview Section 1-1 Note Since the C200HX/HG/HE PCs do not support the CMND instructions, arbi- trary commands cannot be issued. RAS performs real-time monitoring of the network status. If an error occurs in the network, RAS records and displays the time and contents of the error. Status Area Data Link Status Area When the data link function is used, the data link status is reflected in the data...
Page 21 Section 1-1 Overview function enables users to receive only the required data, thereby increasing data link efficiency. Message Service The message service can send and receive up to 2,012 bytes of data (includ- ing the FINS header), allowing high volumes of data to be sent and received without having to split it up.

Manual Setting Options The following options can be set when manually setting data links. Offsets Data of the only the specified number of words can be received starting from the specified word position.
Page 86 Section 5-1 What Are Data Links? Note The Controller Link Support Software contains a function called “Easy Setting” that can be used within the manual data link mode to register the same data links as automatic setting. The “Easy Setting” can be used first, and then the send size of each node and other set- tings can be changed as required.
Page 87: Data Link Specifications
What Are Data Links? Section 5-1 Application Example of In the following example, the send data from node 1 is split into three parts Using Offsets and each part is received by a different node, i.e., each of the other nodes receives only part of the send data from node 1.

It is always possible that the mes- sage may be lost in transit due to noise or some other condition. When using the message service, it is advisable to prevent this situation from oc- curring by performing resend processing at the node where instructions are issued.

Page 207 SECTION 8 Communications Timing This section explains details on Controller Link Network communications. Refer to this section for network communications that require accurate communications timing. Communications Mechanism ........8-1-1 Data Transmissions over the Network .
Page 208: Communications Mechanism
Section 8-1 Communications Mechanism Communications Mechanism 8-1-1 Data Transmissions over the Network Controller Link Token (right to send) In a Controller Link Network, token passing is used to control network access. The right to send, called a “token,” circulates around the network. A node that receives the token is allowed to send data.
Page 209: Setting The Polling And Polled Nodes
Section 8-1 Communications Mechanism Check Check Token circulation Polling cycle Token circulation Polling cycle cycle cycle Communications cycle time Communications cycle time Polling Node Each Controller Link Network always has a Unit that controls communications within the network. This Unit is called the “polling node.” Normally, the node that has the smallest node address in the network is the polling node (see note).
Page 210: Network Parameters
Section 8-1 Communications Mechanism If the node is always to be connected as a polled node when the power is turned on, set it as a polled node. If the node can become a polling node when the power is turned on, set it as a polling node. One of the nodes set as a polling node will serve as the actual polling node.
Page 211: Communications Cycle Time
Section 8-2 Communications Cycle Time The network parameters become valid immediately after being set. Note 1. Always stop the data link before changing network parameters. 2. Specify a value for the maximum node address that is equal to or greater than the maximum node address in the Controller Link Network.
Page 212: Inactive Data Links
Section 8-2 Communications Cycle Time In this example, A to E in the equation have the following values. 8,000 4,024 The communications cycle time is thus as follows: 10 × 8,000 + 600 × 4 + 290 × 8 + 320 × 2 + 4 × 4,024 + 3,290 = 104,746 (µs) ≅...

Page 220 Section 8-3 Data Link I/O Response Time Note If the total number of data link words is greater than the maximum number of words that can be exchanged per data exchange, the maximum data link I/O response time will be cycle time of PC at node #7 × 4. In case of the CQM1H, however, the cycle time will be incremented by the value obtained from dividing the total number of data link words by the maxi- mum number of words (1,200 words) per time.
Page 221 Section 8-3 Data Link I/O Response Time 3. The data transferred in data link processing arrives at the PC at node #7 while data exchange is taking place, so the data will not be read into the PC until the next data exchange, causing a delay of up to one cycle. The maximum number of words that can be exchanged in a single data ex- change is approx.
