Product Description:
The XPC is a general purpose building automation translator with custom programmable functionality,
designed for communicating through multiple protocols. Modbus registers are spawned within the device
as a result of downloading graphical control programs. The XPC translator speaks the Modicon Modbus
RTU Protocol as described in the Modicon Modbus Protocol Reference Guide, PI-MBUS-300 Rev.J, and
acts as a Modbus Master or Slave. Further details on the Modbus supported implementation are
described below.
