  • Page 18: Indication And Settings

    MAC ID duplication error or BUS OFF error (serious communication error) ∗: EX250-SDN1 disconnects the I/O connection when the solenoid valve power supply decreases or when the input block fuse is detected to be broken (EX250-SDN1-X102 does not disconnect the I/O connection).
  • Page 19 ○Switch setting Open the protective cover, and set the switches with a small flat blade screwdriver. Note 1. The power supply should be off while setting the switches. 2. Be sure to set the switches before use. 3. After setting the switches, close the switch cover and tighten the screw to the specified torque. (Tightening torque: 0.6 N•m) Address setting -18-...
  • Page 20 DIP switch position Caution •The default settings are MAC ID 63 and communication speed 125 kbps (Hardware setting mode). •The MAC ID and communication speed set in SW setting mode are maintained even when the SI unit power supply is turned off. When the power supply is applied in HW setting mode, the MAC ID and communication speed set in SW mode are deleted, and the MAC ID and communication speed set by the switches are memorized.
  • Page 21 ○Settings via DeviceNet ® network ® It is possible to set the node address (MAC_ID), DeviceNet communication speed and output condition when a communication error is generated, via the network, in accordance with the procedure below. •Node address setting, communication speed setting 1) Turn SW1-10 on the SI unit ON (SW mode).
