HIMA F6705 Output module

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. 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. Data Integrity 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 INICT12 module. When the INNIS01 module periodically polls nodes, it updates this table accordingly.

Power System Status

 The communication system provides a means to monitor the status of the power system of each node. This status information can be displayed on a human system interface. Electronics within the power entry panel monitor the power system status. A single status output is made available to the communication system. To use this feature, wire the status output to the terminal block on the NTCL01 termination unit labeled PSS1 or PSS2. Two sets of terminals are available on the termination unit for interconnecting the power system status output. This power system status signal is fed through the termination unit cable to the P3 connector on the INNIS01 module. The power system status input is a TTL-compatible signal. A high voltage level (5 VDC) on power system status indicates good status. A low voltage level (0 VDC) indicates bad status. When no connection is made to either of the power system status inputs, a pull-up resistor on the INNIS01 module causes a high level signal on the power system status input, thereby reporting good status. 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 INICT12 module.
