Publication 1770Ć6.5.16 - October 1996
Command Explanation STS Code EXT STS Code
PLCĆ3 physical reads - 10 • There is more than one byte of data after the byte
address.
• The number of bytes to read:
- is an odd number.
- equals zero.
- is greater than the maximum allowed in a reply
packet (244).
• The sum of packet offset and size of data in words
is greater than 65,535.
• The sum of packet offset and size of data in words
is greater than the total transaction size.
- 30 The local PLCĆ3 interface module has executed a
shutdown request.
- 40 A backplane error (memory parity, timeout, or
disconnect) has occurred.
- 70 The local PLCĆ3 processor is in Program mode.
1 F0 There was an error converting the block address
(major section > 63, context > 15, section > 15).
2 F0 Three or fewer addressing levels specified for a
PLCĆ3 word address.
3 F0 The conversion of a file address to a block address
resulted in more than nine addressing levels.
4 F0 The symbolic address was not found.
5 F0 The symbolic address is zero or more than eight
bytes.
6 F0 • The file was not found.
• DST address does not have enough levels to
specify a PLCĆ3 word (for wordĆrange reads) or a
file (for file reads).
• The PLCĆ3 address specifies more levels than
required.
• The word specified by the PLCĆ3 address does not
exist.
7 F0 • Any of the DST words in the DST file do not exist.
• For a file read, the SRC and DST files are not the
same size.
8 F0 The file size decreased between packets of a
multiĆpacket transaction and became too small for
the total transaction.
9 F0 You tried to read or write past the end of a file.
A F0 Start bytes.
