In the above example, the status register for the block mapping has been automatically assigned
to register 9500.
The rest of the mapping configuration involves the mapping trigger - or what initiates the
mapping message.
Firmware versions 1.82 and later.
Block write mappings have option to invert the I/O message that will be sent. This can be
selected when adding a new Write block mapping.
Mapping “Triggers”
A block mapping can be “triggered” or initiated by several different methods.
• By the host device writing to a “trigger register” in the source 105G - the block mapping
message is sent each time the host device writes to the trigger register.
• By configuring a time period - the 105G will send the block mapping message if this time
period has elapsed since the last message has been sent.
• By configuring a real-time clock - the 105G will send the block mapping message at the
configured times.
• By a change-of-state within the I/O block. This can only occur for Write mappings. If a
value in the block changes by more than the sensitivity amount, then only this I/O that has
changed in the block message will be sent. You can enter a delay period such that the
message is sent after the delay period. All I/O that has not changed will not be sent until the
real time clock, time period or host device trigger has been set.
Combinations of the above triggers can occur - for example, the block mapping message will be
sent if a change-of-state occurs, AND at the configured real-time, AND when the host device
writes to the trigger register.
