4.3.22 OPTIONS (Cont.)
TRIAL MODE
Enabling ‘Trial Mode’ allows the user to enable, temporarily, the various software options that are availa-
ble. Once the user has made the required choices, the ‘Set Trial Options’ key at the bottom of the screen,
must be operated, followed by an ‘Autoconfi gure’ procedure.
Initially, the trial mode is set to expire 30 days after enabling (whether the recorder is powered or not).
Any change in confi guration results in a pop-up message stating how much of the 30 days period re-
mains. Once Trial mode is disabled by the user, the remaining Trial Time Remaining’ value is retained
until Trial Mode is re-enabled.
Notes:
1. Trial mode enables/disables all options or features (except ‘Simulation’ and ‘History Mainte-
nance’) which are not fi tted or enabled in the recorder. The number and distribution of virtual
channels reverts to that confi gured before Trial mode was invoked.
2. When disabling Trial mode, all confi guration for the trial features is lost. Should the user decide
to purchase a trial feature, then it is recommended that the trial confi guration be saved (see
section 4.2) so that it may be restored once the purchased trial feature is fi tted and enabled
(keycodes cannot be entered in Trial Mode).
3. Trial mode can be enabled only by users with ‘Perform upgrades’ permission (
section 4.4.1
).
VIRTUAL CHANNELS
Virtual channels are Maths channels, Totalisers and Counters. The total number of virtual channels is as
specifi ed at time of order. A maximum of 128 virtual channels is possible (as a chargeable option). The
user can select whatever combination of maths channels, totalisers and counters is required, so long as
the total does not exceed the number of virtual channels available. If it does, a warning is given when the
‘Apply’ button is operated, and the edit is ignored.
Note: If more than 100 maths channels are required, it is possible to use some of the totaliser
channels modbus address space, however the Modbus register addresses of
totalisers and count-
ers are
affected, to make room for the additional channels.
If for example there were 105 maths channels, the value of the new maths channel 101 would be
at the address normally associated with totaliser 1, in turn totaliser 1 would be found in totaliser
6, and the value of counter 1 would be found at the address normally associated with counter 6.
The 5 new channels being added will increment the exisitng allocated values along by the same
amount of channels being added - to a maximum of 28.
