Data Object
A message generated by a device to indicate that something has happened.
A text file containing information generated by a error condition when running the Settings module. For example, when a device is not connected or is not responding.
FramingFraming determines how many bits there are in a character and what the bits are used for. This includes the number of start bits, the number of data bits, the number and type of parity bits (none, odd or even) and the number of stop bits. Character framing is only used for data transmission on IEC870 connections. A 10 bit frame contains 1 start bit, 8 data bits and 1 stop bit. An 11 bit frame contains 1 start bit, 8 data bits, 1 even parity bit and 1 stop bit. determines how many bits there are in a character and what the bits are used for.
