SIMATIC TI505 Redundant I/O System User Manual
Standard CA TV taps and splitters combine I/O channels from the remote
channel controllers (RCCs) to form two separate trunks (redundant I/O).
Each trunk leads to one of two RBCs located in a chassis that can house two
power supplies, although only one power supply is necessary . When the
active RCC transmits, the dual tap and splitter arrangement splits the
signal three ways:
•T o the stand-by RCC
•T o T runk A
•T o T runk B
When the active RBC transmits, the dual tap and splitter arrangement
splits the transmitted signal from either T runk A or T runk B two ways:
•T o the stand-by RCC
•T o the active RCC
Each redundant RCC, RBC, or power supply can detect internal operating
faults. During normal operation, the RCC detects trunk faults and
recognizes the appearance or disappearance of redundant RBCs and power
supplies. When a fault is detected in the unit designated as active, the
corresponding backup unit automatically assumes control with minimal
process interruption and without operator intervention.
All input, output and SF message transactions occur between the active
RCC and the active RBC. The active RCC directs configuration messages to
both the active and stand-by RBCs, and the addressed RBC is responsible
for acknowledging the message. A “status request” command goes to the
active RBC to determine dual power supply status and to the stand-by RBC
to determine the condition of the stand-by transmitters. If the stand-by does
not respond to this request, the RCC directs the active RBC to command the
stand-by to assume a failed state. When communication problems develop
between the RCC and the active RBC, the RCC directs a “role swap”
command to the stand-by RBC.
The SIMATICTI560T/TI565T System Manual (PPX:560/565–8105–x)
contains detailed instructions for installing remote I/O and for developing a
power budget. The SIMA TIC TI560/TI565 Hot Backup Installation Manual
(PPX:560/565–8103–x) provides details about the additional signal losses
with the Hot Backup Unit. Consult these manuals for installing the overall
I/O system.

SIMATIC TI505 Redundant I/O System User Manual
The user -commanded role swap feature of the Redundant I/O system allows
an orderly transition of the active unit to a stand-by status. The original
stand-by unit then assumes the active role. This feature is accessed using a
task code formatted as follows:
TC = 43FE + LAR + 0310 + RCC + RBC
where LAR = two hex digits,
F1 for role swaps on bases on channels 0 and 1
F2 for role swaps on bases on channels 2 and 3
F4 for role swaps on bases on channels 4 and 5
F6 for role swaps on bases on channels 6 and 7
RCC = single hex digit corresponding to channel number (0 – 7)
RBC = single hex digit corresponding to base number (0 – F)
This task code is transmitted either directly to the Redundant I/O system as
formatted above, or as the body of a native primitive “01” to a TIW AY Host
Adapter.
For example, to command base 0 on channel 1 to do a role swap, send either:
43FEF0031010 task code
or
0143FEF0031010 TIWA Y command
T o command base 15 on channel 7 to conduct a role swap, send either:

SIMATIC TI505 Redundant I/O System User Manual
The Series 500 and 505 Redundant I/O systems each use two power supply
modules, and two RBCs installed in the appropriated dual medial base. The
following power supplies are available:
• PPX:500–2151A and PPX:505–6660A accept 1 10/220 V AC inputs
• PPX:500–2153 and PPX:505–6663 accept 24 VDC inputs
All models provide regulated +5 V and –5 V power to the base. All power
supplies are normally active during dual media operation with each sharing
a portion of the load current. If one power supply fails, the other power
supply provides the full load current and the RBC provides a status
indication that one supply has failed.
Each power supply module provides output overvoltage, overcurrent and
undervoltage protection. The indicator labeled DC GOOD is on when the
module is producing the correct DC power . The indicator is off when
overvoltage, undervoltage, or overcurrent faults are detected.
NOTE: T o allow replacement of a unit without taking down the entire base,
power to each power supply must come from separate sources, and you must
provide a means of disconnecting power from each power supply .
T o install the dual RBCs and power supplies, use either the PPX:500–5864,
8-slot base or the PPX:500–5825 16-slot base with the PPX:500–9940
Redundant Controller Adapter Chassis. The adapter chassis attaches to the
right side of the I/O base and provides slots for the two power supplies and
the two RBCs.
In planning the installation of the I/O bases for the Redundant I/O system,
follow the guidelines in the manual that comes with the bases. T o mount the
PPX:500–9940 Adapter Chassis, see Figure 1-5 for template dimensions,
and follow these steps.
1. When preparing the mounting panel, position the base and adapter for
proper contact of the connectors.
2. Partially insert the two top screws in the panel.
3. Fit the screws into the holes in the adapter base (see Figure 1-5). Slide
the assembly down and to the left until the screws support the adapter
chassis and the base connectors are fully seated.
4. Attach the lower portion of the assembly to the panel with two #10
screws.
5. T ighten all screws.

• Semi-rigid coaxial cable (two sizes) to use for trunk line(s) and for drop
lines
•CA
TV taps to insert in the trunk distribution cable to provide drops
from the active and stand-by controllers to the RBCs
•T aps and splitters to distribute the signal from the active RBC (either
T runk A or B) to the stand-by RCC and the active RCC
• Semi-rigid coaxial cable fittings to connect trunk distribution cable to
tap housing
• F-type connectors to connect drop cable to tap housing
•T erminators to install on all unused terminals on a multi-drop tap
To help avoid potential damage to equipment and/or personal
injury, install redundant I/O components in a non-hazardous
location. For example, ensure that flammable gases are not present
before inserting or removing RBCs or power supplies.
In order to prevent disruption of the I/O channel, disconnect the
coaxial cable before removing or installing an RBC.
To install the Redundant I/O components:
1. Plug an RBC into each of the two designated slots and tighten the top
and bottom screws on each unit. The RBC in the right slot assumes the
active role when the base is powered up.
2. Connect a coaxial cable to each RBC.
3. Plug the power supplies into the designated slots. Be certain the
module is fully seated.
4. After the power supply is inserted, attach the power and ground wires
as shown in Figure 1-8.
