Establishing Communication for Networked Controllers
The following describes the procedure for PIMikroMove and for PITerminal.
INFORMATION
If you are establishing communication with a networked controller via PITerminal, the address
of the controller to be addressed is required in every command line. See "Target and Sender
Address" (p. 117) for details.
➢
Use PITerminal to test communication with networked controllers.
INFORMATION
The RS-232 output lines of some PCs are not adapted for the maximum number of 16
controllers in a network. If you have connected a daisy chain network to such a PC via the RS-
232 interface, communication malfunctions may occur (e.g., timeout). In case of
communication malfunctions:
1.
Disconnect the null-modem cable from the
RS-232 In
socket of the controller which is
connected to the PC.
2.
Connect the daisy chain network to the PC via the USB interface of this controller.
