address

Monitor Point #
Monitor

addr

Require

Select

Each point is one bit and the DB address value corresponds to the bit offset in
the database.

The database address should be located in a database area that is being
constantly moved from the MVI69-101S to the CompactLogix or MicroLogix
processor. You should configure the DB address parameter in an area that is on
a Backplane Command Function 2.

2.13 [C_DC_NA_1]

This section defines the double point command database for the slave emulated.
This information is sourced from the remote master and is transferred to the
database. Each point occupies two bits in the database. You can associate a
command with a monitored double point database value to coordinate the
command/monitor operation. You must enter the correct Monitor Point # and
Monitor DB addr values in the table. If the Require Select parameter is not set to
zero, a select command must be received before an execute command will be
processed.

2.14 [C_RC_NA_1]

This section defines the step command database for the slave emulated. This
information is sourced from the remote master and is transferred to the database.
Each point occupies a byte in the database. The control value can be associated
with a monitored point as described in the previous example.

This section takes the following parameters:
