8.7 Non Procedure Protocol Receive Data Clear

This section explains how to clear the received data using the non procedure protocol.

By using this function, the receive data can be cleared from GX Configurator-SC while

the communication with the non procedure protocol is still in progress, without resetting

the PLC CPU or turning off the power.

[Operation procedure]

(Procedure 1) Display the [Non procedure monitor/test] screen. (See Section 8.6.5.)

(Procedure 2) Set [Clear request issued] for "Receive data clear request".

(Procedure 3) Click on Execute test

The received data will be cleared.

POINT

Clear the received data when transmission/reception are not in progress with the

external device.

Executing a receive data clear while the data transmission is in progress causes

the Q series C24 to stop the data transmission abruptly, resulting in an abnormal

completion of the dedicated transmission instruction. (The transmission completion

signal will not be lit.)

When the receive data clear is executed while the data reception is in progress, the

data received up to that point will be cleared.
