SP UNIT ERROR
– The location designated by a link direct device
(J\) is not a network module.
– The I/O module (intelligent function module/
special function module) was nearly removed,
completely removed, or mounted during run-
ning.

– Read the individual information of the error
using the GX (IEC) Developer, check the
FROM/TO instruction that corresponds to that
numerical value (program error location), and
correct when necessary.
– The intelligent function module/special func-
tion module that was accessed is experienc-
ing a hardware fault. Therefore, change the
