FIELDBUS FEATURES

• 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)
