PPX:505–6860 RS-485/RF I/O Channel Converter
Installation
About
this Pr
oduct
These instructions describe the installation of a
PPX:505–6860 RS-485/RF I/O Channel
Converter in the SIMA
controller
The PPX:505–6860 converter allows the use of
coaxial cables in a 505 system (extending the
maximum distance to 4 km) by converting the
RS-485 interface to an RF interface. This also
permits use of dual media from a 545/555 to the
I/O bases.
Installing a PPX:505–6860 converter also
allows you to update an existing 560/565
system, that is already using coaxial cables,
with a 545/555 and 575
advantages of greater speed, dual media, and
greater remote distance.

Installation Procedure
Installing the PPX:505–6860
Use the following procedure to install the
PPX:505–6860:
1.
Remove the power from the base in which
you are installing the PPX:505–6860.
2.
In the case of a 545/555 installation, install
the PPX:505–6860 in the same base as the
CPU and in the first double I/O slot
adjacent to the CPU.
In the case of a 575 installation, the
PPX:505–6860 must be installed in a 505
base within three feet of the 575 base that
is electrically bonded to the 505 base.
3.
Use an RS-485 cable to connect the CPU
and PPX:505–6860 RS-485 I/O ports
together
. The RS-485 cable should be as
short as possible.
The correct wiring for the cable that
connects from the 545/555/575 CPU to the
new PPX:505–6860 RS-485 I/O channel
converter is shown in T
able 1. This is
different from the normal connections for
an RS-485 I/O channel in that a cable with
two twisted, shielded pairs with 9 pin,
subminiature, male D-connectors at each
end is required (instead of the single pair
cable that is normally used). Pair like
named signals 3 and 8, and 4 and 9.
4.
Connect the RF (coaxial) cable to the
PPX:505–6860 port that is labeled:
RF TO I/O BASES
NOTE:
All the remote bases connected to a
.
See Figure 1.
545/555/575 CPU must have RF RBCs. RS-485
bases cannot be connected between the CPU
and the PPX:505–6860.

Upgrading an RF-Based TI560/TI565/TI560T/TI565P to a TI545/TI555/TI575

, including its chassis,
, and all its installed boards
with the 505 base, the 505 power supply
545/555 CPU, and RF/RS-485 converter
upgrade to a 575 system, replace the existing
programmable controller, (including its chassis,
its power supply
with a 575 base, 575 Power Supply
, and all its installed boards)
, 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.
NOTE:
The 545/555 cannot directly replace
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
W
iring 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
Manual
(PPX:575–8101–x) for information
SIMA
TIC 575 System
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.
,
. T
,
3.
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
o
additional 505 modules, if desired.
4.
Modify the controller’s I/O configuration to
reflect the channel number and base
number changes.
5.
Connect the resulting I/O channel to the
545/555 or the 575 system using the
PPX:505–6860 RS-485/RF I/O Channel
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
SF modules and installing them in the 545/555
local base.
If all SF modules cannot be installed in the
local base, consider placing low-activity SF
modules, such as the ASCII, BASIC, or DCP
modules, in a remote base. Place high-activity
modules, such as the NIM or Peerlink, in the
local base.
