Data Sheet
IQ204/ADL
STRATEGY
The strategy processes inputs according to a set of instructions and then outputs signals which can be used to control equipment.
Configuration: The IQ204/ADL uses the standard IQ
configuration mode which enables configuration using the
network, or using the supervisor port (either using modem or by
local PC). SET can be used to create a strategy data file (.IQ2)
which can then be downloaded to the controller if connected to
the controller directly or using the network. The strategy file can
be uploaded using the modem for backup purposes.
Modules: The strategy consists of a number of individual
functional blocks known as configuration modules. These blocks
can be linked in various combinations to enable equipment to be
controlled in accordance with the building’s requirements. The
table lists the different types of configuration modules and the
number of each type available with IQ204/ADL.

Full details of the modules are given in the IQ Configuration
Manual and Addendum. The IQ204/ADL also contains the
standard IQ2 features as described in IQ Configuration Manual
Addendum: Engineers Journal (J), I/O Summary (i/o) Loader
Issue (R(c), ’c’ lower case), Serial Number (R(s), ‘s’ lower case),
Supply Frequency Option, Enhanced Logging, Module position,
and Strategy Cleardown.
Differences between the modules covered in the manuals and
the IQ204’s modules are described below.
Line Sharing: As explained in the manuals, changing modem
initialisation string 2 in the modem module (to ATS0=0) enables
the modem to share a line; the modem can dial out with alarms,
but it will ignore incoming calls, so cannot be accessed from a
supervisor.
Dual Strategy Backup: Two strategy files may be stored in nonvolatile
memory (i.e. retention is independent of controller's
battery). The strategy backup modules can be accessed in
configuration mode by character '#'. There are two modules (#1
or #2). Since the controller will load the strategy from module 1
if it detects a corrupted memory condition, it is recommended to
keep module 1 as the current strategy backup.

Entering 'S1' will cause the controller to respond with the following
message while it suspends strategy operation and saves the
strategy to the relevant strategy backup module in non-volatile
memory:
'Please wait saving strategy to location 1'
Entering 'R1' will cause the controller to respond with the following
message while it suspends strategy operation and restores the
strategy from the relevant strategy backup module in non-volatile
memory:
'Please wait restoring strategy from location
1'
The instructions can be given by text comms commands e.g.
'#1(S=1)' causes a save to module 1, and '#2'(R=1) causes a
restore from module 2. IQ system software tools can implement
these commands by text comms or configuration mode; the GDP+
can be programmed to execute the commands using text comms.
It is recommended that the running strategy is backed up in
strategy backup module 1 so that it will be restored after a strategy
cleardown due to a faulty battery. Backup module 2 may then be
used to store a default or alternative strategy.
Strategy Cleardown: The IQ204 has a modified version of IQ2v3
strategy cleardown because it is able to restore the strategy from
a strategy backup module. If there is a strategy file backed up in
module 1, it will restore the file after loss of data during power
down due to a faulty battery (i.e. checksum error or checksum
invalid). If there isn't a strategy file backed up in module 1, it will
null down the memory, set the address module ID and attributes
to indicate 'Strategy Erased', and enter a CONL condition
(Controller on line - restart).
Note that the time, date, and day of week will need to be set up;
this can be done automatically by a timemaster.
Other methods of strategy cleardown act as normal and leave
the controller with a null strategy and any strategies backed up
will still be set up in the strategy backup modules; however, a
firmware upgrade will clear down the strategy backup modules.
