This error occurs if you attempt to access an illegal address in a

controller

. The 1773-KA module then aborts the message.

Illegal accesses may result because:

Invalid Read/W

rite length or

All Bit writes not to the same PLC-4 or

Invalid address or

iolation

The command cannot be executed because of the switch

settings on the 1773-KA module.

The controller you have addressed is in Program mode. This

error results in setting the remote error bit for the associated

rung.

1773-KA unable to buf

fer message in memory. This error will

only be signalled after 5 re-tries at half second intervals. It

indicates that either a very heavy traf

fic load is being presented

to the remote station, or that the dynamic memory of the remote

station is corrupted. If the problem clears up after cycling

power and does not recur the cause may be RAM or CPU

failures triggered by heat or noise. If the problem recurs

repeatedly the probable cause is too many messages.
