ArmorStart® ZIP Configuration 12-3
Data Production In a typical ZIP system, each device on the network automatically
produces IO data using “Change of State” (COS) triggering. The
automatic production of this COS data by an ArmorStart is enabled
by setting Parameter 67 (AutoRun ZIP) to a value of 1 = Enable. Then
COS data will be produced automatically when the global ZIP enable
parameter (Zone Ctrl Enable, Parameter 99) is set to the value of 1 =
Enable. Data production will take place at a rate specified by
Parameter 68 (Zone ProducedEPR). The minimum period between
Change of State productions is determined by the value of Parameter
69 (Zone ProducedPIT)
Data Consumption In the ArmorStart data from up to 4 other devices can be consumed
for use in the local logic. The 4 devices whose data is to be consumed
are logically referred to by zone number, i.e. zones 1 – 4. To configure
an ArmorStart to consume data from another node on the network, the
node address or “MacId” is placed in the proper “Zone MacId”
parameter (parameters 70-73). For example to configure an
ArmorStart to consume data for zone 1 from node number 11 on the
network, the value 11 is placed in Parameter 70 (Zone #1 MacId).
Not all zones need to be configured to consume data. If the user
wishes to turn off data consumption for a zone, the value 64 is placed
in the Zone MacId parameter for that zone.
The ArmorStart monitors the frequency at which all consumed data is
received in order to determine the health of each zone’s data
connection. The Zone EPR parameters (parameters 86-89) define the
“Expected Packet Rate” for each of the 4 zone connections.
If no consumed data for a zone is received in 4 times the EPR, then
the zone connection times out, and the value of the corresponding
“Zone Health” parameter (parameters 74-77) is set to the value 1 =
Not Healthy. The “Zone Health” status of each zone is also available
for use in DeviceLogix programs.
Mapping Consumed Data to the
DeviceLogix Data Table. Consumed data for the 4 zones is placed in an 8 byte section of the
DeviceLogix Data Table. Individual bits in this section of the
DeviceLogix Data Table can be used in DeviceLogix programs. The
table below shows the organization of the 8 bytes of the data table
