Each block mapping that is configured is allocated a status register in the range 9500 – 9999 (i.e.
one status register for a maximum of 500 possible block mappings). The status register for a
given block mapping is shown on the right hand side of the Block Mapping display (under the
heading “Status Lcn”). Bit 13 of the associated status register is the “Force bit” - if Bit 13 is
turned “on”, then the associated mapping is forced, or triggered. Depending on the module
version, a particular algorithm may apply to the setting of the force bit. This algorithm and details
of the block status registers are given in Appendix 1.

Time Period
On the Block Mapping display, there are two configuration windows - “Period” and “Offset” -
these determine the time period trigger and real-time trigger.
For a time-period trigger, select “Continuous” in the “Period” pop-down window. Under
“Offset” enter the time-period in seconds. In the above example, the mapping will be sent every
300 seconds or 5 minutes.
Note that the time period is after the last transmission - if the block mapping message is triggered
by the host device, or by a change-of-state, then the timer is reset and the time period starts again.
The “Offset” value can be set from 0 – 4095 seconds (68 minutes). If you do not want the
message to be sent on a time period, set the “Offset” value to zero.
If you want the block mapping to be sent only on time period (and not on change as well), select
the “Disable” box in the bottom left hand corner - this disables change messages for this block
mapping. If you want any changes sent within this Time period uncheck Disable box and enter
in time to wait before sending only the I/O that has changed in the Block.
