Description

QRC_RECEIVE_POLLING_TIME

100ms

Polling time for the TCP connection

QRC_RECEIVE_TIMEOUT

10s

Time for receiver timeout

QRC_BUFFER_SIZE

2500

QRC frame buffer size in byte

QRC_NUMBER_OF_CONTROL

50

The maximum number of controls that are allowed to send, to receive and to extract.

Param 1:

1. QRC_BUFFER_SIZE defined the length of sending buffer sTxFrame. Before each QRC frame is transmitted, this QRC frame was measured and checked whether the length of this frame is greater than QRC_BUFFER_SIZE. In some cases (e.g. Hundreds of controls are transmitted via Control.Set or Component.Set) the buffer is easily overloaded. If the buffer has been overflowed, an error "Buffer overflowed" will occur before transmitting this QRC frame. This QRC frame will be ignored until the value of QRC_BUFFER_SIZE has been increased.

2. QRC_BUFFER_SIZE is considered to be highly relevant to QRC_NUMBER_OF_CONTROL. In consequence, the value of QRC_BUFFER_SIZE has to be changed accordingly. (The Proportion 1:50 (1 control - 50 Byte) is recommended).
