BC Criteria for Valid Transactions
Valid Transactions result in generation of GOOD XFER (INT 0) Interrupt.
Invalid Transfer result in generation of INVALID TRANSFER (INT 1) Interrupt.
See Transaction Word for additional Status Word Criterion (i.e. bit masks)
General Validity Criteria - Applies to all transfers
A. Bus must be quiet, i.e. no additional data words, status words or command words after correct RT response
before transaction is declared valid.
B. If data is returned, word count, must be correct. Data must also be contiguous, i.e. no gaps.
C. RTU Address(s) must be correct in returned status word(s).
D. RTU must respond within 14μsec (except for non RT to RT Broadcast).
E.
No bits set in returned status word(s), except where masked in transaction word.
Interrupts In BC Mode
Transaction Type
Specific Validity Criteria
1. Normal Data Transfer
A. RT to BC
B. BC to
RT
C. Broadcast
(Tx/Rx = 1)
(Tx/Rx = 0)
(Tx/Rx = 0)
Status, then Valid Message
Status
No Status
2. RT to RT Transfer
A. Normal
B. Broadcast
(Tx/Rx = 1)
(Tx/Rx = 1)
Status, Valid Message,then Status
Status, then Valid Message only
3. Mode (no data)
A. Normal
B. Broadcast
Status
No Status
4. Mode (associated data)
A. Normal
B. Broadcast
Status
No Status
5. Mode (returned data)
Status, then returned data
BC Interrupt Name
Signal Name
Conditions and Actions
Good Transfer
INT 0
1. Indicates fully valid transaction.
2. Initiates next poll operation, when in polling mode.
Invalid Transfer
INT 1
1. Non masked bits set (includes reserved bits).
2. No status (2 for non BCST RT to RT) word returned.
3. Status word has incorrect address.
4. Fail safe time out (1 millisec)for bus (RTU) to go quiet i.e.
RTU loudmouthing.
5. Incorrect number of data words.
6. Busy (even if busy masked) when RTU should receive or
transmit data.
Note: busy mask only masks busy for mode cmds.
Poll Operation Complete
INT 2
1. Indicates end of poll,when end of poll is a valid transaction.
2. Delayed from good transfer interrupt.
3. Initiates poll sequence again (from offset) if in continuous
mode.
4. If the I/O command "continue at next transaction" is issued at
the last transaction command, this interrupt will be issued.
