W&T OPC data transfer
22�3�3 Structuring the serial data
In order to be able to represent the received RS232 data for
OPC as string variables, the data must first be broken down
into packets. Packet limits are recognized here either based
on pauses or by the occurrence of special character se-
quences. Character sequences are always indicated indirectly
as decimal numbers.
Examples:
1.) End string: +++ r Input: 43,43,43
2.) End string: CRLF r Input: 13, 10
