UNDEFINED MODE CODES
(T/R = 0, MODE CODES 00000 TO 01111)
No Response, set message error bit.
RESERVED MODE CODES (10110-11111)
MESSAGE SEQUENCE = RESERVED MODE CODE (T/R = 1) * STATUS
RESERVED MODE CODE (T/R = 0) * STATUS
If Valid (T/R = 0)
The RTU responds with status. If the command was broadcast, the broadcast received bit is set and status transmission is suppressed. If the com-
mand is illegalized through an optional PROM, the message error bit is set and only the status word is transmitted.
If Valid (T/R = 1)
Respond with status and one data word.
ERROR CONDITIONS (T/R = 1)
1. Invalid Command. No response, command ignored.
2. Command Followed by Data Word. No status response. Bits Set: message error (SW), High Word Count, Illegal Mode Code (BIT Word).
ERROR CONDITIONS (T/R = 0)
1. Invalid Command. No response, command ignored.
2. Command not followed by Contiguous Data Word. No status response. Bits set: message error (S/W), Low Word Count,
Illegal Mode Code (BIT Word).
3. Command followed by too many Data Words. No status response. Bits Set: message error (S/W), High Word Count,
Illegal Mode Code (BIT Word).
OVERRIDE SELECTED TRANSMITTER SHUTDOWN (10101)
MESSAGE SEQUENCE = OVERRIDE SELECTED TRANSMITTER SHUTDOWN * STATUS
The data word received after the command is transferred to the subsystem. No other action is taken by the RTU. If the command was broadcast,
the broadcast received bit is set and status transmission suppressed.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Not Followed by Data Word. No status response. Bits Set: message error (SW), Low Word Count, Illegal Mode Code (BIT Word)
3. Command Followed by too many Data Words. No status response. Bits Set: message error (SW), High Word Count,
Illegal Mode Code (BIT Word)
4. Command T/R bit Set to One. No status response. Bits set: message error (S/W), Illegal Mode Code, High Word Count (BIT Word).
5. Command T/R bit Set to One and Broadcast Address. No status response. Bits set: message error, broadcast received (S/W),
Illegal Mode Code, High Word Count, T/R Error (BIT Word).
SELECTED TRANSMITTER SHUTDOWN (10100)
MESSAGE SEQUENCE = SELECTED TRANSMITTER SHUTDOWN * STATUS VECTOR WORD
The data word received is transmitted to the subsystem and status is transmitted. No other action is taken by the RTU. If the command was
broadcast, the broadcast received bit is set and status transmission suppressed. Intended for use with RT’s with more than one dual redundant
channel.
ERROR CONDITIONS
1. Invalid Command. No response, command ignored.
2. Command Not Followed by Data Word. No status response. Bits Set: message error (SW), High Word Count, Illegal Mode Code (BIT Word)
3. Command Followed by too many Data Words. No status response. Bits Set: message error (SW), Low Word Count,
Illegal Mode Code (BIT Word)
4. Command T/R bit Set to One. No status response. Bits set: message error (S/W), Illegal Mode Code, High Word Count (BIT Word).
5. Command T/R bit Set to One and Broadcast Address. No status response. Bits Set: message error, broadcast received (S/W),
Illegal Mode Code, High Word Count (BIT Word).

* = Status Response Time
