1.2. ERROR DETECTION
There are two types of errors which may occur in a communications system: transmission errors and programming or operation errors.
The Modbus system has specific methods for dealing with either type of error. Communications errors usually consist of a changed bit or bits within a message. For example, 0001 0100 may become 0001 0110, changing the decimal value from 20 to 22. It is much less common to have a bit added to or deleted from a message. The most frequent cause of communications errors is noise: unwanted electrical signals in a communications channel. These signals occur because of electrical interference from machinery, damage to the communications channel, impulse noise (spikes), etc. Communications errors are detected by
character framing, a parity check, and a redundancy check.
