Top Node
Content
The reference number entered in the top node is the first position in the destination
block–i.e., the block where the current words of interest from the status table will be
copied. The reference may be:
The first 0x reference in a block of contiguous discrete outputs
The first 4x reference in a block of contiguous holding registers
Bottom Node
Content
The integer value entered in the bottom node specifies the number of registers or
16-bit words in the destination block where the current status information will be
written.
The length–i.e., number of words–in the status table will vary depending on
whether or not I/OBus I/O is being supported:
Without I/OBus, the STAT instruction is 12 words long.
With I/OBus, the instruction is 20 words long.
