Byte 5 in the routing path (DNDE_LO) is determined as follows:
The station address of the remote bridge is 240 octal (10100000).
The station address of the final Data Highway Plus station is 4
(00000100).
DNDE combines the upper two bits of the remote bridge station
address with the lower six bits of the final Data Highway Plus station
address (10000100). This is equivalent to 84h.
4.2.6.2 Example of Bridging the DH+ Link to a ControlNet Network
Using AutoMax and its 57C442 Data Highway Plus interface module to
send and receive data file values to a Control Net PLC5 through a
ControlLogix gateway. Knowledge Base Document 10628 defined the
network layout and network routing table set-ups. This document will
show the network and which parameters relate to the AutoMax.
Network Configuration
The 57C442 AutoMax Data Highway Plus module has the ability to
perform “Off-Link Routing”. This routing is used to move data from one
network to another network. This is covered as a separate subject in
the modules instruction manual. Twelve bytes of data are required in
order to program this function in the AutoMax. For the network
configuration shown above, they are:
