Message Transmission Any INNIS01 module can transmit a message at any time without regard to the activities of any other INNIS01 module on the Cnet network. Each INNIS01 module can transmit and receive messages simultaneously. Startup and shutdown is local and requires no interaction with other INNIS01 modules on the network. Each module receives all incoming messages and transmits a new stream of messages in a store and forward fashion to the next node. When there are no messages for the INNIS01 module to transmit, the module transmits flag characters (null packets) as the loop synchronizing condition to keep the receivers in lock.There are three methods by which the INNIS01 module insures data integrity. They are retry logic, node status table, and polling. Retry Logic If, on the first transmission of a message, the INNIS01 module does not receive positive acknowledgment from the destination node, it retransmits the message 11 times. If after this series of retries there is still no response, the destination node is marked offline.

Node Status Table

 The INNIS01 module maintains an internal table of system wide node status such as offline and busy. The INNIS01 module relays node status changes to the INICT03 module. When the INNIS01 module periodically polls nodes, it updates this table accordingly. Polling The INNIS01 module uses the information in its status table for polling purposes. As it scans the status table, it picks out destinations targeted for multicast messages that have been marked offline or busy. After polling the destination, the INNIS01 module updates its table and forwards pertinent information to the INICT03 module. INICT03 Computer Transfer The INICT03 module handles all communication with the host computer through its IMMPI01 module using either SCSI or RS-232-C communication. When communicating through an RS-232-C serial port, the IMMPI01 module can act as data communication equipment (DCE) or data terminal equipment (DTE). The jumper configuration on the NTMP01 termination unit determines DTE or DCE operation. The INICT03 module has enough memory to store up to 30,000 point definitions (depending on point types). The module firmware enables the host computer to issue commands for data acquisition, process monitoring and control, and system
