HS (Handle Switch)
[Configuration]
DESCRIPTION:
The HS command is used to switch the handle assignments between two handles. Handles are assigned
explicitly with the
IH (Internet Handle) command, or automatically if a remote device initiates the
connection. Should those assignments need modifications, the HS command allows the handles to be
reassigned. This is very useful if using the
MB (Modbus) , MG (Message) , or SA (Send Command)
commands, which expect a certain device to be present on a specific handle.
ARGUMENTS: HS a=b where
a = the first handle of the switch (A - H)
b = the second handle of the switch (A - H)
USAGE:
RELATED COMMANDS:
IH (Internet Handle)
EXAMPLES:
This example demonstrates a master controller, M2, searching for other controllers on each handle and
forcing them to communicate at a specific handle. This is necessary when using the
@IN (Input) , SB (Set
Bit) , CB (Clear Bit) , SA (Send Command) or MB (Modbus) commands, because they reference specific
handles.
The Jump condition logic below ((_IHA0+4)<>_IA)|(_IHA2<>2) is basically running the SH (Servo
Here) command on the given line if the IP address is not equal to the controller own IP address + 4 and if
the connection type is not TCP/IP.
