12-30 Output Functions

The second input argument is the decimal node address of the PLC remote device
(0 through 254). If the number is not within this range, the status equals 2 and the
write message does not occur.

The third input argument is the file number to be written to on the PLC remote
device (0 through 255). If the number is not within this range, the status equals 2
and the write message does not occur. The parameter is PUSHed, but ignored, if
the common interface file is chosen in the first parameter.

The fourth input argument is the destination file type on the remote device. This
number is ignored if the common interface file is chosen in the first parameter
(assumes integer file). If the file type code is not one of these shown below, the
status equals 2 and the write message does not take place.

The fifth input argument is the starting word offset within the file on the PLC-2
remote device (0 through 32766). For PLC-3 integer, binary, or status files, the
value is 0-9999 (decimal). For PLC-3 I/O files, the value is 0-4095 (decimal). For
PLC-3 timer or counter files the value is 0. If the number is not within this range,
the status equals 2 and the transfer does not occur.

The sixth input argument is the number of elements to be transferred. If the
number is not within the range shown below, the status equals 2 and the transfer
does not occur.
