CompoWay/F Master Protocol
Broadcast with ASCII Conversion, No Response
(Sequence No. 601 (Hex 0259))
This sequence converts the specified data beginning with the command code to ASCII and broadcasts it. No
responses are received.
Send Data Word Allocation (3rd Operand of PMCR(260))
Note 1. Set the number of send bytes to twice the number of bytes in memory. This is necessary because the
data is converted to ASCII data before being sent.
2. When hexadecimal data is converted to ASCII data, data is sent starting from the send data word with
the largest offset. This is done because ladder programming handles data in 4-byte units.
Receive Data Word Allocation (4th Operand of PMCR(260))
None. (Specify a dummy value for the operand, such as #0000.)
Send with No Conversion and with Response
(Sequence No. 602 (Hex 025A))
This sequence sends the specified data beginning with the command code to the specified Unit. The response
is stored starting at the specified word. No conversions are performed on the send and receive data.
