HEIDENHAIN iTNC 530 HSCI - Module 9076 Read Symbolic PLC Operand

1746 HEIDENHAIN Technical Manual iTNC 530 HSCI
Module 9076 Read symbolic PLC operand
PLC Module 9076 reads a symbolic PLC operand whose name is contained in
a PLC string.
Transfer:
 String with symbolic operand name
 If it is a string memory, the second parameter is the address of the target
string.
Returns:
 Identifier of operand type, 0 in case of error
 Data from PLC operand, if B/W/D/M/I/O/C/T type
Constraints:
 The module can only be called from a SUBMIT/SPAWN job.
Call:
PS B/W/D/K/S<>Address of string buffer>
or constant string, e.g. PS S“DG_MP_DATA[68]“
PS B/W/D/K <>Address of the source string>
If the string was addressed, this is the address of the target
string.
