78 Procedures for installing I/O modules in the controller rack and I/O expansion
racks, and for wiring field devices to the terminal block associated with each
I/O module.
Communications
Installation
127 Guidelines for installing RS-232, RS-485 to USB cable, RS-485, and Ethernet
cabling and associated components.
Operating
Characteristics
155 Characteristics of the HC900 Process Controller as they relate to configuration of
a control strategy, and to operation of an installed and running system.
Redundant
Operating
Characteristics
165 Characteristics of redundant operation.
Diagnostics and
Troubleshooting
173 Mechanisms that detect and react to faults in the operation of HC900 Process
Controller hardware and/or software components.
Analog Calibration 191 Hardware configuration required for calibrating AI and AO modules from the
configuration software.
Removal and
Replacement
Procedures
196 Guidelines for replacing system components; includes Cautions and Warnings as
applicable.

Appendix -
Installation of
Remote
Termination Panels
(RTPs)
217 The Remote Termination Panel (RTP) provides an easy way to connect the
HC900 controller to the field wiring. The RTP integrates some of the typical
externally connected components, reducing wiring and setup time. It also
minimizes the need for multiple wires under a single screw connection by
expanding the connectivity of the shared terminals of the I/O modules.
