2.2.21 Function serial communication COM and EXP
Communication functions COM and EXP enable the programming of the
serial ports (COM1-RS485 and EXP1-RS232) for reading/writing of data
from connected slave devices using the master protocol selected in the
project. These functions are active only when in the project a master
communication protocol has been selected for the relevant serial port. A
Master protocol means a protocol which enables the PL260 to control the
serial line communication, controlling the data flow towards slave devices.
The two functions are similar, they only refer to a different serial port.
Instruction COM operates with interface RS485, allowing to connect more
devices on the same line, while instruction EXP operates with interface
RS232 allowing to connect one single device to PL260. Instructions are
active while the relevant coil is active. Consider also that, according to
