Master).
KEY POINTS
Other F145 (SEND) / F146 (RECV) instructions cannot be executed at the
•
same time to a communication port during master communication. Confirm
that the "SEND / RECV executable flag" is ON, and execute the instructions.
• F145 (SEND) / F146 (RECV) instruction cannot be executed at the same time
to a port during slave communication.
• The processing of F145 (SEND)/F146 (RECV) instruction is handled during
the execution of ED instruction. Check the SEND / RECV done flag to
confirm the completion of transmission / reception. Turned ON in the case
of an error, and an error code is stored in DT90123-DT90125.
In the case of COM0 port, specify "HF" as a COM port No. for an operand of
•
the F145 (SEND) / F146 (RECV) instruction.
 Special relays / special data registers
SEND / RECV executable flag
SEND / RECV done flag
SEND / RECV done code
(Note): The Nos. in brackets indicate devices that are compatible with existing FP-X / FPΣ.
5.2 MEWTOCOL-COM Master Communication (RECV)
Specify the number of words in higher words of control data.
Range: H1 to H1FD (1 word to 509 words)
Specify a COM port No. for the higher 4 bits in lower words of control data.
HF: COM0 port; H1: COM1 port; H2: COM2 port
Specify a unit number of a destination unit for the lower 8 bits in lower words of
control data.
Range: H01 to H63 (K1 to K99)
Specify the starting number of the area (2 words) that specifies the transfer
method and the number of transfer data.
This is inserted to confirm that no SEND / RECV instruction is in progress for
the same port. Turns ON when an instruction is executable.
Using two operands, specify the type and relative address of the memory area
of a destination unit that stores receive data.
Specify the memory area of the master unit that stores receive data.
