IMPORTANT
The examples use PLC-5 and SLC 5/04 controllers to send DH+ messages. In
each case, the use of these devices is strictly for example purposes and not
an indication of restrictions on the 1756-DHRIO and 1756-DHRIOXT
modules.
Examples using PLC-5 controllers could, in fact, use SLC 5/04 controllers and
examples using SLC 5/04 controllers could use PLC-5 controllers.
