From the I/O Driver, the SDOR instruction runs
the SDO command (read) defined in the source operand. After the I/O
Driver completes the SDO command, execution results are set to the
destination operand.
From the I/O Driver, the SDOW instruction runs
the SDO command (write) defined in the source operand. After the
I/O Driver completes the SDO command, execution results are set to
the destination operand.
From the I/O Driver, the DGMT instruction reads
the master diagnostic results. The I/O Driver then sets the read
results to the destination operand.
From the I/O Driver, the DGSL instruction reads
the slave diagnostic results defined in the source operand. The I/O
Driver then sets the read results to the destination operand.
Instructions execute when they receive power. The
instruction passes power for one scan after the instruction
completes execution.
