OPERATING PROCEDURES
INIIL02 MODE OF OPERATION

I-E96-607A
®
Stop/Reset Switch
Push the stop/reset switch once and wait for the status LED to
turn red before removing the INIIT03 module from the module
mounting unit.
After the module is stopped, pushing the stop/reset switch
resets the INIIT03 module. This action:
1. Resets the module to power up values after a stop.
2. Recovers from an operator-initiated stop or module
time-out.
INIIL02 MODE OF OPERATION
The INIIL02 INFI-NET to INFI-NET Local Interface has one
mode of operation. The module should be in execute mode. If
not, it has failed or there is some other problem with the mod-
ule. In the execute mode, the INIIT03 module transfers data
and status information from the central INFI-NET communica-
tion loop to the local satellite INFI-NET communication loop.
INTERFACE POINT CAPACITY
There are three factors that determine the maximum number
of points in an INIIL02 interface configuration: Point type
(exception report data type), the number of devices that receive
each distinct (unique) exception report and the total memory
available (1.66 megabytes). Table
lists the memory usage
for routing records. Table
lists the memory usage per tag
and point type.

Bridge
18
A bridge is any local or remote INFI-NET to INFI-NET communication
interface or INFI-NET to Plant Loop communication interface. One
bridge record is created for each bridge other than the one under con-
sideration.
Node
50
The INIIL02 interface allocates a node record for each node on the cen-
tral loop and each node on the satellite loop.
Module
14
One module record is allocated for each remote module from which the
INIIL02 interface imports or exports exception reports.
Block
(refer to
Table
One block record is required for each exception report being imported.
Remote route
12
A remote route record is required for each destination of an exception
report. The maximum number of destinations can be approximated by
summing the number of consoles and bridges on each communication
loop connected to the INIIL02 interface.
NOTE: 1.The INIIT03 module has 1.66 megabytes of RAM available for use.
