1.1 Features
The TI545/TI555 CPUs and support equipment comprise a
computer -controlled system that is capable of controlling complex
manufacturing systems. This system performs the same functions as relays,
static control, or card logic control systems. It can detect the change in state
of input signals from such devices as pushbuttons, limit switches, and
analog sensors.
Acting on this information and executing a Relay Ladder Logic (RLL)
program stored in memory , the TI545/TI555 CPU produces output signals to
drive motor starters, solenoids, pilot lights, modulating control valves, etc.
These signals are used to regulate the operation of various pieces of
equipment.
The TI545/TI555 systems offer the following features:

System Overview
TI545/TI555 System Manual
The TI545/TI555 controller system uses individual Series 505 or Series 500
I/O modules for I/O interfaces. A full line of discrete, analog, word, and
intelligent I/O modules are available for handling almost any input or
output specification. These I/O modules are rugged, plug-in devices capable
of functioning in harsh environments within the operating specifications.
The controllers can also communicate with other devices through the
SINECr H1 or SIMA TICrTIWAY Local Area Networks. See documents
listed in the Preface of this manual for information on these systems.

1.2 Hardware Description
The CPUs are housed in a Series 505 base assembly. A base assembly has
slots for the CPU or remote base controller (RBC), a power supply , and the
I/O modules. Three base assembly models are currently available. Each has
the following number of slots for I/O modules.
• Model PPX:505–6504, 4 slots.
• Model PPX:505–6508, 8 slots.
• Model PPX:505–651 1, 1 1 slots (redundant). Power supply and media.
• Model PPX:505–6516, 16 slots.
Any base assembly may be used at any point in the system, depending upon
the number of I/O points required.
I/O modules are grouped into local and remote I/O categories depending
upon their physical location. The local I/O comprises those modules located
in the same base assembly as the CPU. If you install the CPU in base
assembly Model PPX:505–6516, the local I/O may consist of as many as 16
I/O modules. The base assembly containing the local I/O is designated 0.
Y ou can connect up to 15 additional base assemblies to the system,
numbered 1–15. The I/O modules in these bases make up the remote I/O as
shown in Figure 1-2.
Individual I/O modules in the remote bases communicate with the CPU
through RBCs. The RBC in each remote base transmits information from
the I/O modules in that base directly to the CPU.
The power supply provides up to 55 W at +5 VDC and 3.75 W at –5 VDC for
use by the CPU and the I/O modules. The PPX:505–6660 power supply
operates at either 1 10 V AC or 220 VAC on user -supplied power . A jumper on
the inside of the back of the module is used to select voltage. The model
PPX:505–6663 power supply operates on 24 VDC user -supplied power .
