A great function of the 140CPU43412A is the 1.2 Ah Lithium 7 µA 210 µA battery. With it’s 10 year battery life this module lasts long and is very efficient within this time. It has 2 remotes networks and 3 distributed networks allowing a wide range of connection. It has 3 ports including 1 Modbus plus, 2 Modbus RS232.This module is functionally identical to the non-A version. However, If you are using the module in a Hot Standby topology, then you need to use two non-”A”models or two A models. The A version has a unique flash executive. The “A” version and non-”A” flash executives are not interchangeable

Another feature 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.

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 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.
