Description
When using it as an indirect address, use the indirect specification of the device specified in the global label.
■Example of ST
ADRSET(TRUE , intVar , gvAddr); // Read the intVar indirect address to gvAddr.
INC (TRUE , @D0);// Use the indirect specification of device D0 specified for gvAddr.
Transfer the indirect address to the device and use the indirect specification of the transfer destination device.
■Example of ST
ADRSET(TRUE , intVar , lvAddr); // Read the intVar indirect address to lvAddr.
DMOV(TRUE , lvAddr , D0);// Transfer the indirect address, which has been read to lvAddr, to the device.
INC (TRUE , @D0);// Use the indirect specification of the device to which the indirect address was transferred.
