@ Description

HSL_A_start_read:

Initializes the reading operation of the analog input channels of all

HSL AI/O modules that are connected to the master card. Before

using HSL_A_read_input(), HSL_A_write_output() and

HSL_A_sync_rw(), the functions must be executed to start the A/D

conversion.

HSL_A_stop_read:

Stops the reading operation of analog input channels of all HSL AI/

O modules that are connected to the master card. Use this func-

tion to stop the A/D conversion.
