In any of the following cases, an operation error occurs, the error flag (SM0) is turned ON, and
the corresponding error code is stored to SD0.
(1) When the specified value is outside of the following range. (Error code: 4101)
• When the number of write points n3 is other than 0 to 320.
• When the beginning of the CPU shared memory address n2 of the write destination host
CPU exceeds the CPU shared memory range.
• When the CPU shared memory address n2 of the write destination host CPU + the
number of write points n3 exceeds the CPU shared memory range.
• When the start number of the devices that stores the data to be written + the number of
write points n3 exceeds the device range.
• When the host CPU operation information area, restricted system area or host CPU
refresh area is specified for the CPU shared memory address n2 of the write destination.
(2) When the I/O number specified for n1 is other than that of the host station.
(Error code: 2107)
(3) When the number specified for n1 is other than 3E0
