Specifying Network Parameters
Active Data Links
Note
The network parameters can be specified from the Controller Link Support
Software. This section describes only the allowable setting range for each net-
work parameter. Refer to the Controller Link Support Software Operation
Manual (W308) for setting procedures.
The following table shows the setting range and default for network parame-
ters.
The network parameters become valid immediately after being set.
1. The setting range will be 2 to 62 and the default value will be 62 when the
2. Always stop the data link before changing network parameters.
3. Specify a value for the maximum node address that is equal to or greater
4. For the CVM1 and CV-series PLCs, always set the System Protect Key
5. The maximum node address cannot be changed to 32 when the Wired
This section describes how to calculate the communications cycle time.
The following equations are used to calculate the communications cycle time
when data links are operating.
