Communications Cycle Time

Section 8-2

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.

3.

For the CVM1 and CV-series PCs, always set the System Protect Key
Switch on the CPU Unit to NORMAL. Otherwise, the network parameter
settings will not be stored normally.

Communications Cycle Time

This section describes how to calculate the communications cycle time.

8-2-1

Active Data Links

The following equations are used to calculate the communications cycle time
when data links are operating.

Wired Systems

Note A: Total number of data link words within the network 

(total number of words in send areas of all nodes)

B: Number of polled nodes per comm cycle

(value specified in the network parameters)

C: Number of nodes connected to the network
D: Number of nodes that send messages during the 

communications cycle

E: Total number of bytes in messages transmitted during the 

communications cycle

The number of bytes in each message differs according to the instruction
being issued.

Calculation Example

Communications conditions are as follows:

Transmission medium:

Twisted-pair cable

Baud rate: 

2 Mbps

Network parameters: 

Defaults

Max node address: 

32

Polled nodes per comm cycle: 

4

Event-frames per comm cycle: 

35

Network configuration:

8 nodes

Total number of data link words:

8,000 words

Nodes that send messages: 

2 nodes

Bytes in all messages sent: 

2,012
