CJ-series PROFIBUS Master Unit Operation Manual for NJ-series CPU Unit (W509)
The PROFIBUS network allows to connect and disconnect devices while in operation.
 Connecting / Disconnecting Devices
Connecting/disconnecting any device in a PROFIBUS network is liable to result in a temporary
increase of the communication cycle time. An existing slave device can only be replaced by the
same type of device with the same configuration. Any change to this configuration is likely to require
a new configuration. Changing a device with a different device (type and/or configuration) will have a
significant influence on the performance on the PROFIBUS network.
 Adding a Device
The addition of a new device to an existing configuration will require a new configuration file to be
downloaded in the PROFIBUS Master Unit, which will temporarily disable all communication by this
Unit on PROFIBUS.
