    Introduction to Modbus - Automation

    Note: Some Modbus software will misinterpret "no parity" as equivalent to "no bit transmitted". According to the Modbus standard, no parity will add an additional stop bit (maintaining an 11 bit data frame in RTU mode). To prevent potential incompatibilities, Acromag 900MB modules are designed to accept messages with no parity and 1 or 2 stop bits. Understanding the differences between Modbus and Modbus Plus are very important. Modbus is based on the RS232C serial standard communications that define the cabling, connector pinouts, signal levels, parity checking, and transmission baud rates. It’s a master slave protocol that uses the Modicon controllers through a common language.
