upload all request (upload)
Places a PLC-5 processor in Upload mode before uploading a
complete system. (A T50 terminal displays “download” mode.)
A “no privilege“ error is returned if the programmed device does not
have the privilege of placing the processor into Upload mode.
This error occurs when:
the processor is being edited
some other node is already uploading or downloading to the
processor
If you have an earlier version of a PLC-5 processor, this error may
occur if your processor is not in Program or Remote Program mode.

A - number of uploadable segments of PLC5 memory in the remote PLC5 processor
B - (eight bytes for each segment specified in A.) First 4 bytes contain the starting address of
the segment. The second 4 bytes contain the ending address of the segment.
C - number of comparable memory segments.
D - (eight bytes for each segment specified in C.) The first four bytes contain the starting
address of the segment. The second four bytes contain the ending address of the segment.
A, B, C, D - These fields may be replaced by an EXT STS field if there is an error
.
If you are using a PLC-5 family processor other than a PLC-5/15
(Series A or Series B Revision E or earlier), you also receive data
about uploadable and comparable memory segments:
Segment Description
uploadable memory
Contiguous segments of the PLC5 memory that must be
uploaded.
comparable memory
Uploadable contiguous memory segments that you can compare
to an uploaded segment to verify the contents. For example, a
segment of memory that contains ladder logic is comparable,
but a segment that contains data table memory is not because
because data table memory is constantly changing.
