Receive Data Word Allocation (4th Operand of PMCR(260))
Parameter Area Broadcast Send
(Sequence No. 617 (Hex 0269))
This sequence writes the specified number of elements from the address of the specified parameter area using
a broadcast address.
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 a0 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.
Receive Data Word Allocation (4th Operand of PMCR(260))
None. (Specify a dummy value for the operand, such as #0000.)
