HSL Function Library 91

Reads the digital input value of the discrete I/O module at a speci-

fied channel.

HSL_D_write_output:

Writes the digital output value of the discrete I/O module. You must

specify the connect index and slave index.

HSL_D_write_channel_output:

Writes the digital output value of the discrete I/O module at the

specified channel.

HSL_D_read_ouput:

Writes all digital output values to all connected discrete I/O mod-

ules. This function maps all data into memory. With this function,

you can write all digital output values to all connected discrete I/O

modules at one time.

HSL_D_read_all_slave_input:

Reads the digital input values from all slave I/O modules with set

value of connect_index and card no is card_ID. This function

allows you to read all digital input values from all slave I/O mod-

ules at one time.

HSL_D_write_all_slave_output:

Writes the digital output values from all slave I/O modules with set

value of connect_index and card no is card_ID. This function

allows you to write all digital output values from all slave I/O mod-

ules at one time.

HSL_D_set_input_logic:

Sets the digital input logic to the specified slave I/O module. The

slave I/O module‘s address is slave_No and set value is

connect_index.

HSL_D_set_output_logic:

Sets the digital output logic to the specified slave I/O module. The

slave I/O module‘s address is slave_No and set value is

connect_index.

HSL_D_set_int_renewal_type (7853/54 only):

Sets the type of hardware interrupt occurrence timing. These are.
