Zone Interlock Protocol (ZIP)
Zone Interlock Protocol (ZIP)
The Zone Interlock Protocol (ZIP) menu is available for devices that support the
DeviceNet™ Zone Interlock Protocol Object. The Zone Interlock Protocol
provides a way for devices to share I/O message data directly, and the data that is
consumed from other devices can then be used in a DeviceLogix™ program. The
ZIP Choices Menu is displayed by selecting ZIP and pressing the
Enter
key at the
Advanced Functions Menu. The following menu choices are available to edit and
monitor the ZIP configuration:
ZIP Consumed This screen allows the operator to configure the ZIP data that the device is going
to consume. Configuring ZIP Consumed data consists of mapping I/O data from
other nodes or zones on the network to the device’s internal ZIP Data Table (the
ZIP Data Table is where a DeviceLogix™ program accesses ZIP data). Devices
that support ZIP can define the number of zones from which they can consume
at one time. In this manual it is assumed that the device can consume data from
up to four zones at one time. The size of the internal ZIP data table is device
specific. In this manual it is also assumed that the internal ZIP data table is eight
bytes long.
The following screen shows a device with no ZIP I/O data configured or
mapped:
Zone number (1…4) that is associated with data currently
highlighted. Note: x = no zone is associated at this time
The Node Number of
the device whose I/O
data is mapped in
this zone
This is the internal zip data
table. B:00-07 indicates that
we are viewing data table
bytes 0…7 (B:08-15 would
be displayed on the next line
if the data table was 16 bytes
long). Each XX represents one
byte in the data table. The XX
will display the Devices Node
Number whose I/O data is
mapped to that byte in the
ZIP data table.
