CompoWay/F Master Protocol Appendix B
2. The read data is returned as 4-digit hexadecimal as follows: F0019999 to 00099999 Hex.
The 3rd and 4th operands of the PMCR(260) instruction are specified as follows.
Send Data Word Allocation (3rd Operand of PMCR(260))
Receive Data Word Allocation (4th Operand of PMCR(260))
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.
