Explanation

X90 - X9F

Clear to send master

communication flag

When connection is ON in the master communication mode, the

flag is ON.

Y90 - Y9F

Sending master

communication flag

Turns ON during sending data based on SEND/RECV command.

Turns OFF when ED command is executed following response

reception processing.

Y70 - Y7F

Sending done result flag

Reports completion result of sending data in general-purpose

communication or master communication. (Normal completion: 0,

Abnormal completion: 1)

(Note 1) Each contact is used for reading the operation status. Do not write over it with a user program.

KEY POINTS

•

Specify the connection No. targeted for communication, using UNITSEL

command immediately before SEND/RECV command.

•

Master communication is only valid when MEWTOCOL or MODBUS is

selected. Confirm that the "clear to send master communication flag" (X90 -

X9F) for the targeted connection is ON,, and execute SEND/RECV command.

•

You cannot execute other SEND/RECV command for connection in master

communication. Confirm that the "sending master communication flag"

(Y90 - Y9F) is OFF, and execute command.

•

You cannot execute SEND/RECV command for connection in slave

communication.

•

Up to 16 SEND/RECV commands can be executed simultaneously for

different connections.

•

In the case of communication between FP7 LAN ports, specify "U1" for the

partner station no. The receiver is specified by IP address.
