The 140CPU43412A firmware supports up to six network modules (i.e., Modbus Plus, Ethernet, and Multi-Axis Motion option modules) using the option module interface technique. However, only two Modbus Plus modules can have full functionality, including Quantum DIO support.

One of the advantages of the 140CPU43412A is the single slide switch. The single slide switch is used to select the comm parameter settings for Modbus (RS-232) Ports. It also has a key switch which is used to protect memory from programming changes while the controller is in operation. This enables the 140CPU43412A module to be safe and secure while operating.

One more function is the address switch. The address switch, which is comprised of two rotary switches, is located on the rear panel of the Quantum CPUs. The address switch is used for setting Modbus Plus node and Modbus port addresses. This is a great plus for users as it keeps things organized. The 140CPU43412A’s processor supports up to six network modules (i.e., Modbus Plus, Ethernet, and Multi-Axis Motion option modules)  using the option module interface technique allowing flexibility and variety.. However, only two Modbus Plus modules can have full functionality, including Quantum DIO support.
