Telegram time
The telegram always contains the time information for the "next" second for periodical
telegram output. The telegram content is valid at the send time of the first character.
The send time of the telegram can be shifted with the parameter TC (e.g. the standard
IF 482 telegram valid at the end of the telegram).
The transmission time of a time telegram can be calculated with the following table.
According to the transmission format set, the transmission time in ms for one character
is read from the table and multiplied by the number of telegram characters:
Example:
9600 Bit/s, 8 data bits, none, 1 stop bit, the telegram has 20 characters.
Transmission time for the entire telegram:
20 x 1.04 ms = 20.8 ms
Name of the telegram file
The telegram file name is limited to 8 characters and its extension has to be TEL, Tel
or tel, e.g. IF482Std.tel.
