The group of Power Modules affected by the communication time-out event is defined
with the
TOGRP
(Time-Out Group) command and it is not the same group as defined
by the GRP command.
Turn-on and reset behavior
When the XMP 2600 is powered-up and the time out feature was enabled when the XMP
2600 was last used, one of two things may happen, as summarized below:
Power On Retain
Time Out counter starts
enabled
immediately following the retain operation
disabled
following the first character received from the remote controller
If the XMP 2600 is being reset using the front panel key combination
(DEL+LCL) then the time out feature will be disabled. All other reset
operations do not disable the time out feature.
Time out events as reflected in the status structure
Bit 3 of the Status Byte Register (read with *STB or Serial-Poll) is assigned to the
Remote Communications Time-Out Event. The bit will be set when such an event occurs
and if the corresponding bit of the Service Request Enable Register is set then the event
will cause an SRQ to be generated.
The status bit is cleared when the TORST command is issued.
