SIOX Climate Controller Module
T05
General Description
T05
is a general microprocessor controller
with
enhanced PLC programmability and
SIOX
field bus communication. It
comprises
two analog outputs and two
inpu
ts. Analog input 1 handles voltage /
current
or thermistor input. Analog input 2
is
preconnected for thermistor input.
Three
digital inputs, two outputs, two
power
relays and one alarm relay are
included.
T05
can work standalone or together with
other
SIOX I/O modules communicating
over
a common wire pair for climate
control,
energy optimisation and alarm
handling.

Block Diagram
Power Supply
The
T05 is supplied with 18 V - 35 V DC via the two terminals marked “-/+
24VDC”
on the PC board corresponding to terminals 11/12 in the Block
Diagram
above. The supply GND terminal is connected directly to the I/O GN D
terminals
and the Functional Earthing terminals. Alternatively, a 48 V supply
may
be connected between terminals 28 (+) and 27 (-), which renders DI6 un-
usable.
An external
fuse must be provided on the positive supply with a rating of max
1
A, Quick Blow. The contacts of the two power relays can carry max 10 A at
230 V AC each, and must be externally fused with max 10 A,
Time Lag (Anti Surge), HRC (High Rupture Capacity) fuses.
T05 CLIMATE CONTROLLER MODULE p 4
T05-1
can alternatively be powered from 230 V mains v ia a built-in transformer.
This
connection is shown on next page and must use a separate Pg16 cable
gla
nd and include an external power switch and a fuse of max 10 A. The
current
of the two digital outputs are, howev er, limited to some 10 mA each by
the transformer capacity.
Installation and Start-Up
The
T05 is typically wall mounted using the four corner holes. This mounting
does not affect the IP 65 case sealing. Cables must be entered via cable
glands
that are adequately tightened to prohibit the cords from being pushed
into/pulled
out of the unit. The unit is a Class II equipment intended for
Installation
Category II. Please follow the instructions described under “Safety
Precautions” on page 18.
Terminal Blocks
T05 CLIMATE CONTROLLER MODULE p 5
Typically, a two-wire, low capacitance twisted pair is used for the SIOX com-
munication
bus. Shielded cables may be used but unless a correct strategy for
shield
grounding is adopted, it may prove to be of little benefit. The total
resistance of the bus must be low, typically below 2 * 50
.
When
a proper supply and the SIOX bus have been connected, the com-
munication
can be tested and operating modes and application PLC program
entered.
Unless otherwise requested, the module is preset at the factory to
communicate
at 4800 bits/s using address 01. General principles for the SIOX
bus
and communications are described in a separate manual, the "SIOX
System
Description". Changes in operation modes are brought about by
Parameter
Setup Strings communicated over the SIOX bus, described on page
10.
Address Setup
There
are two ways of defining each of the 63 addresses for a T05 module,
either
through jumpers or by the internal EEPROM in the module. If any combi-
nation
of jumpers except all six installed or all six removed is used at power-up,
the module will choose this jumper combination as the correct address.
= 00 : Illegal, will use EEPROM definition.
= 63 : Illegal, will use EEPROM definition.
= 25 : Valid address (16 + 8 + 1 = 25).
The
jumper positions A
0/ - A5 contribute their values 1, 2, 4, 8, 16 and 32 when
the corresponding jumper is
removed
.
All
jumpers installed would generate the invalid address 00, and all jumpers
removed
would be equal to the "reserve" address 63. In this case, the module
checks its internal parameter
0/1 for a valid
address number. Should none be
found, address 63 will be selected.
The
selected address, either from the jumpers or the EEPROM, is finally saved
in
the RAM parameter
0/1
and used for all subsequent communications until this
parameter
is changed or a new power-up is performed. Changing the RAM
address
can be done from the master or from the local PLC program in the
module,
but make absolutely certai n to avoid collision with other modules on
the bus.
T05 CLIMATE CONTROLLER MODULE p 6
A
special feature is added to help recover "lost" modules, i.e. when an unknown
bit
rate and/or address is selected or the PLC runs a program that erroneously
alters
parameters affecting the communication. To recover such a module,
carry out the following steps:
1.
Disconnect power.
2.
Remove
all address jumpers except for A0 and A1 but
rotate
these two
jumpers 90
from their normal position. Please refer to the figure below.
3.
Apply
power. The module will now communicate at 4800 bits/s using
address 63 with the PLC and any options disabled.
4.
Check and reconfigure the module for proper operation.
5.
Restore correct jumper address.
Analog Outputs
The
analog outputs are controlled by values entered in two parameters hex
0/C
and 0/D
and provide pos it i ve voltages between 0 V and 10 V at loads up to 5
mA.
An individual control flag in parameter
0/4/0/
5 changes the range
to 2 - 10
V for either output to suit some types of valves etc.
Analog Output Overrange / Underrange
Normal
12-bit AO control range is hex
0/0/0/0/ - 10/0/0/
= 4097 values within 0 - 10
V
for both AO. AO2, however, being a 10-bit converter will set an output to one
of
1025 values within 0 to 10 V. This means that typically 4 consecutive 12-bit
values,
e.g.
0/0/0/4
- 0/0/0/7, in String Mode or double-byte Data Mode will
generate the same output. (Single-byte Data
Mode permits only 128 different
levels).
Negative
control values, hex 8
0/0/0/ - FFFF (or in Double Data Mode hex 2
/0/0/0 -
3FFF) will set the output to zero (or 2 V if this offset is active).
Positive values hex 1
0/0/0/ - 7FFF will set the output to 10 V.
