Index Compatibilitatis

• Use this Y-coupler within the specified redundant-controller Y-Link arrangement; verify the installed bus module.
• Check that the bus-module supply remains within 20.4–28.8 V DC and that the lower-level PROFIBUS DP segment is terminated correctly.
• Count the connected DP devices: up to 31 without repeaters, or up to 64 with the documented RS 485 repeaters or OLM/OBT.
• Match the lower-level DP transmission rate to the documented 45.45 kbit/s–12 Mbit/s range and provide an enclosure suitable for IP20 equipment.
