FIELDBUSFEATURES

4hfNETLOGIC

•no input & output cabling to PLC

•each slave node needs to be addressed

•communications diagnostic available

•easy network plug & play expansibility

•high number of I/O through a single PLC

•guaranteed transmission speed

•PLC is always isolated from the field (PLC supplies the field-bus only)
