SLC 5/04 Controllers
This chapter describes how to use DH+ messaging between PLC-5 and
SLC 5/04 controllers.

DH+ Messaging: PLC-5 to PLC-5/C Controllers on the

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.
