QUICKDESIGNER Reliance AutoMate
201
Destination Slot
The Destination Slot is the default slot number.
Gateway ON
This option informs the target display that the AutoMate Gateway will be in use. When the Gateway is
ON, there are two more menu options that require entries. They are "Gateway Max Nodes" and
"Gateway Config'', which are discussed in the next two sections.
Gateway Max Nodes
Each unit connected to a R-Net network must have a unique node number. The node number is the
address used in the communications protocol. Node numbers range from 0 to 31 decimal for a
maximum of 32 nodes on a network. For maximum throughput, node numbers should be assigned
beginning with node zero and be assigned consecutive numbers. Gaps in the node number assignment
causes a 10 millisecond increase in the amount of time required for information to be passed around the
network. The Max number causes the Gateway to restart with the first assigned node when the
maximum node number is reached. This number should be one higher than the highest node number on
the network.
Gateway Configure
If the Gateway loses power, the target display will reset the Gateway parameters after receiving a error
message. The Gateway response delay parameters as follows:
00 = 0.2 sec. 10 = 2.6 sec.
01 = 0.5 sec. 11 = 2.9 sec.
02 = 0.8 sec. 12 = 3.2 sec.
03= 1.1 sec. 13 = 3.5 sec.
04 = 1.4 sec. 14 = 3.8 sec.
05 = 1.7 sec. 15 = 4.1 sec.
06 = 2.0 sec. 16 = 4.4 sec.
07 = 2.3 sec. 17 = 4.7 sec.
The target display will configure the Gateway with the node number, the maximum number of nodes,
and the config value of the response delay.
