12-16 SLC Communication Instructions
Specifies the node number of the target device that is receiving the
message.
Processors running OS Series C, FRN 6 and higher, can execute a
broadcast write MSG command by entering in a target device local node
address of 255 (decimal) using RSLogix 500 version 5.20 or higher. A
broadcast write command is executed simultaneously by every node that
receives it, but no node acknowledges or responds to it. The broadcast
write command is valid for DH-485 and DF1 networks only. Broadcast
is not supported for read commands or any remote messages.
• Ethernet (IP) Address
(1)
Specifies the Ethernet IP address of the target device that is receiving
the message. When using OS501, Series C, FRN 5, or higher firmware
and RSLogix 500 version 5.20, or higher programming software, you
may optionally enter in the device name (as defined on your local
network’s Domain Name System (DNS) servers), in place of the target
device’s Ethernet IP address. (RSLogix 500 versions 6.30 and below
place an additional restriction on the device name that it must start with
an alpha character A to Z.) This device name must be no longer than 41
characters. You must have a Primary Name Server and/or Secondary
Name Server defined in the Channel 1 Ethernet configuration to
successfully use this device name functionality. If you have a Default
Domain Name defined in the Channel 1 Ethernet configuration, then
the Default Domain Name is appended to the device name when
requesting the corresponding IP address from the DNS server.
• MultiHop
(2)
Specifies whether or not the message is either routed to an EtherNet/IP
device, such as a Logix controller or an Ethernet Network interface
(1761-NET-ENI), or through a ControlLogix gateway (1756-ENBT). If
yes, then the target device Ethernet address or MSG route must be
configured in the MultiHop tab of the MSG Setup Screen.
