2.3 Configure ModBus™ Device ID
Two BCD switches are provided to allow external definition of 0 to 247
ModBus addresses. Prior to operation the user must set the desired
Device ID number for the ModBus communications. Each address must
be unique. To set the Device ID remove the Black hole plug from the
bottom of the unit. Locate the LSB and MSB rotary switches. Set the
binary address by rotating the switches to the desired address. The
Switch is Binary encoded and has a range of “0 - F”. Reinstall the hole
plug after setting the Device ID number. The maximum Device ID is
restricted to 247 as specified by the ModBus Protocol standard. See
Appendix D for Device ID MSB and LSB Decode Table.
