Upgrading an RF-Based TI560/TI565/TI560T/TI565P to a TI545/TI555/TI575
To upgrade an existing RF-based 560, 560T,
565, 565P

system, replace the existing
programmable controller, including its chassis,
its power supply, and all its installed boards
with the 505 base, the 505 power supply,
545/555 CPU, and RF/RS-485 converter. To
upgrade to a 575 system, replace the existing
programmable controller, (including its chassis,
its power supply, and all its installed boards)
with a 575 base, 575 Power Supply, 575 CPU,
575 Remote I/O Annex, 505 base, the 505 power
supply, and RF/RS-485 converter. The upgrade
to a 545/555 is shown in Figure 2, and the
upgrade to a 575 is shown in Figure 3.

either a hot backup (HBU) configuration or a
system with more than 15 bases.

1.
If the Series 500
remote I/O installation
consists of more than one coaxial (RF)
remote I/O channel, combine these
channels into a single remote I/O channel.
Refer to the section entitled, “Cabling and
Wiring the System,” in the your system
manual for information about installation
of a coaxial remote I/O channel.

2.
If the system has more than 15 bases,
multiple VME 575 CPUs can be used.
(Each 575 controller has its own I/O
channel. Refer to the SIMATIC 575 System
Manual (PPX:575–8101–x) for information
on installation and operation of the 575.)
However, using multiple CPUs may
require significant program modifications
in order to divide the 565 program and
redistribute the program among the 575
CPUs.

Re-number your bases between 1 and 15 so
that no two bases have the same number.

Base number 0 is the local base where the
CPU resides and may be used for
additional 505 modules, if desired.

Connect the resulting I/O channel to the

Converter.
6.
When using a 545/555 controller, connect a
120 ohm resistor between pins 3 and 8 on
the RS-485 I/O connector of your CPU, in
order to properly terminate the I/O
channel data lines. When using a 575
controller, set jumper E8 on the Remote
Annex from the “U” position to the “T”
position to activate termination.

Update time for a special function (SF) module
is significantly faster when you install the
module in the local base, rather than a remote
base. You can improve both SF module
performance and scan performance by replacing
the Series 500 SF modules with Series 505

If all SF modules cannot be installed in the

modules, such as the ASCII, BASIC, or DCP
modules, in a remote base. Place high-activity
