	Using a Quantum 984 HSBY System

Controlling the	If you are upgrading from a 984 Hot Standby system to a Quantum system, you may
Hot Standby	port your ladder logic program by first deleting the HSBY block, then relocating the
System by CHS	program, and then inserting a CHS instruction. This requires the CHS loadable to be
instruction	installed into your application.
