Block Transfers with the 1756-DHRIO or 1756-DHRIOXT Module Chapter 12
Block Transfers to Remote
FLEX I/O Modules through
a 1756-DHRIO or
1756-DHRIOXT Module in a
Local Chassis
This application enables a ControlLogix controller to initiate block transfers to
remote FLEX I/O modules through a 1756-DHRIO or 1756-DHRIOXT
module in the local chassis.
The following figure illustrates the steps you must use in this example.
Configure the Module Switches
Channel B on the 1756-DHRIO or 1756-DHRIOXT module must be set for
RIO. Channel A can be used for remote I/O or DH+, regardless of the usage
assigned to channel B.
Configure the 1756-DHRIO or 1756-DHRIOXT Module
Use the Studio 5000 environment to configure the 1756-DHRIO or
1756-DHRIOXT module. The following figure shows some sample
configuration dialog boxes for the 1756-DHRIO or 1756-DHRIOXT module
in this example.
