IMPORTANT
The examples use PLC-5s and SLC-5/04s 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
module. Examples using PLC-5s could, in fact, use
SLC-5/04s and examples using SLC-5/04s could use
PLC-5s.
