Message
Description
6015
Ack Timeout - Out
The Master inter-module process attempted to
initiate a packet transmission to a Slave inter-
module process, but a timeout occurred waiting for
the Slave’s acknowledge.
6016
Ack Timeout - In
The Master inter-module process attempted to
initiate a packet transmission from a Slave inter-
module process, but a timeout occurred waiting for
the Slave’s acknowledge.
6017
Ack Invalid - Out
The Master inter-module process attempted to
initiate a packet transmission to a Slave inter-
module process, but the Slave’s acknowledge was
invalid.
6018
Ack Invalid - In
The Master inter-module process attempted to
initiate a packet transmission from a Slave inter-
module process, but the Slave’s acknowledge was
invalid.
6019
Comm Port Ack Error
The Master inter-module process, after sending a
control byte to a Slave, was waiting for an
acknowledge, but the UART detected an error
condition.
6020
Command Overlap
The Master inter-module process received a
Command from the Master control process, but a
previously issued command is still being executed.
6021
Slave RTS Still Set
The Master inter-module process has received a
valid acknowledge from a Slave, but the Slave’s
RTSi line has remained asserted.
6022
Slave Addr Invalid
The Master inter-module process received a
CommBlock from the Master control process, but the
specified Slave address exceeds the maximum valid
range.
6023
Slave Req Unknown Power
Down To Clear
The Master inter-module process detected an active
SRVREQ line, but, after sequencing through all slave
addresses, determined that no Slave had its RTSi
line asserted.
