8.5.2 Transmitting Characters
There are two modes available:
a) Unformatted output: The Transmit command transmits data from a
PLC transmit buffer (DM, DF, DB) without conversion by the serial inter-
face. Reformatting is not implemented, i.e., a 0FFH in the memory causes
a 0FFH in the line.
Using this procedure, the user can easily output self-formulated request
and acknowledgement information. For example, if the connected device
at the start of the communication requires an STX control character, this
can be edited as a hex word (STX = 02H) combined with a text character
in the memory which is to be transmitted. This control character is then
transmitted with the other data.
b) Formatted output: In some applications (e.g. printer..) texts or texts
with variables must be output according to the following display types
- Hex
- Decimal
- ASCII characters
- Floating point
The Formatted Output command, described on Page 71, fulfils these re-
quirements.
