Local versus Remote type
Message
Local Message
A Local MSG is used to transmit data from one processor to another on the
same network. If two processors are connected together a Local type message
is used to transfer information from one to the other.
Remote Message
A Remote MSG is used to exchange information to a device that is not
connected on the local network. A device (another processor or an actual
bridging device) on the local network will act as a bridge or gateway to the
destination network.
IMPORTANT
Refer to the SLC 500 Modular Hardware Style User
Manual, publication 1747-UM011, for the setup of
DH-485, DH+, and Ethernet networks, as well as DF1
