MESSAGE SEQUENCE - OVERRIDE SHUTDOWN - STATUS
This command is only used with dual redundant bus systems. The CT2553-PCB responds with status. At the end of the status
transmission, the CT2553-PCB re-enables the transmitter of the redundant bus. If the command was broadcast, the broadcast received
bit is set and status transmission is suppressed.
MESSAGE SEQUENCE - INHIBIT TERMINAL FLAG * STATUS
The CT2553-PCB responds with status and inhibits further internal or external setting of the terminal flag bit in the status register. Once
the terminal flag has been inhibited, it can only be reactivated by an Override Inhibit Terminal Flag or Reset RT command. If the
command was broadcast, the broadcast received bit is set and status transmission is suppressed.
MESSAGE SEQUENCE - OVERRIDE INHIBIT TERMINAL FLAG * STATUS
The RTU responds with status and reactivates the terminal flag bit in the status register. If the command was broadcast, the broadcast
received bit is set and status transmission is suppressed.
MESSAGE SEQUENCE - RESET REMOTE TERMINAL * STATUS
The CT2553-PCB responds with status and internally resets. Transmitter shutdown, mode commands, and inhibit terminal flag
commands will be reset. If the command was broadcast, the broadcast received bit is set and the status word is suppressed.
MESSAGE SEQUENCE = RESERVED MODE CODES * STATUS
The CT2553-PCB responds with status. If the command is illegalized through an optional PROM, the message error bit is set and only
the status word is transmitted.
