Serial Signals
Serial signals are much like analog signals, in that they, too, contain 16 bits of
information. However, whereas the value of an analog signal is used directly–to
control volume or temperature, for instance–the value of the serial signal is used as a
pointer to a location in memory that contains a string of characters. When a serial
signal is routed to a symbol, that symbol can identify the signal as serial rather than
analog and it will automatically look at the data to which it points.
Thus, serial signals are used to facilitate the transmission of serial data (strings of
characters). These signals can be generated by incoming data on a COM port or by a
symbol that has a serial output.
STX-1700CXPW Input/Output Signals
The STX-1700CXPW symbol provides up to 4000 digital joins, up to 1024 analog
joins, and up to 127 serial output joins and 255 serial input joins. The programmer
selects the signal types by clicking on the appropriate button at the top of the Symbol
Detail view when programming the panel.
The following tables list functional descriptions for touchpanel outputs and inputs.
