Frequently Asked Questions
Q: What communication networks does the 140CPU43412UC support?
A: It has integrated Modbus Plus and Modbus interfaces. Additional communication options include Ethernet, Profibus DP, Sy/Max and other supported modules, subject to the configured hardware and connection limits.
Q: Does the 140CPU43412UC support Ethernet remote I/O?
A: The supplied specifications list zero Ethernet remote I/O stations. Although Ethernet TCP/IP connections are listed as supported locally, this should not be interpreted as native Ethernet remote I/O station support.
Q: What is the significance of the UC configuration?
A: The complete reference identifies the conformal-coated Unity processor configuration. Schneider Electric identifies this product as a 1056 kB, 66 MHz coated Modicon Quantum Unity processor. Retain the complete 140CPU43412UC reference when checking replacement or procurement requirements.
Q: Is the 140CPU43412UC discontinued?
A: Yes. Schneider Electric lists this reference as discontinued. Its published service status and end-of-service dates vary across regional product pages, so confirm regional support availability before planning maintenance or replacement. The manufacturer lists BMEP581020H as a recommended replacement, but this should be treated as a migration candidate rather than an automatically interchangeable module.
