Number Of Elements "0001 - Omron SYSMAC CS1W-SCB41-V1 Operation Manual

CompoWay/F Master Protocol
The received frames are stored in order from the leftmost word to the rightmost word of the I/O memory
address.
Parameter Area Write
(Sequence No. 616 (Hex 0268))
This sequence writes the contents of the specified number of elements from the address of the specified
parameter area to the specified node number.
Send Data Word Allocation (3rd Operand of PMCR(260))
Set the number of write bytes to twice the of the actual number of send data bytes. This is necessary because
the data is converted to ASCII data before being written. When hexadecimal data is converted to ASCII data,
data in the first write address +0 and +1 is stored in I/O memory in order from the leftmost word to the rightmost
word and the data is sent starting from the send data word with the largest offset. This is done because ladder
programming handles data in 2-word (4-byte) units.
