Description

Use the DTL_WRITE_W_IDX function to write a file to the PLC-5

programmable controller connected directly to the control coprocessor.

This function is synchronous. When this function is initiated, your

C application program stops until the function completes or fails.

To use this function, the data definition must specify the address to the first

element of the file and the number of data items must be 1.

You can address structured data types to either the structure level or the

element level. When you address to the structure level, the data type must

be RAW.

Valid Definition Examples

DTL_C_DEFINE (&idl, “N34:0”) /* specified to element 0,

default 1 item */

DTL_C_DEFINE (&idl, “T4:0.pre”) /* index 0 accesses T4:0.pre; index 14

accesses T4:14.pre */

DTL_C_DEFINE (&idl, “T4:0,1,raw”) /* index 0 accesses all three elements of

T4:0 (control, preset, accumulator);

index 14 access all three elements

of T4:14 (control, preset, accumulator)*/
