In this example, the controller reads 10 elements from the target's N7 file,
starting at word N7:50 using 500CPU Read command. The 10 words are
placed in the controller's integer file starting at word N7:0. If 33 seconds
elapse before the message completes, error bit MG11:0/ER is set,
indicating that the message timed out.
If the target device is another MicroLogix 1400, a SLC 5/05, a PLC-5E or a
controller connected to Ethernet via a 1761-NET-ENI, then simply enter in
the device’s IP address in the “To Address” column as shown below under
the MultiHop tab.
