Coordination flag
The coordination flag serves to coordinate the receipt of data. The
coordination flag is set by the FETCH order. As long as the flag is set, no
other FETCH order may be released. If you want to prevent that data are
overwritten after receipt by new data, the deployment of the coordination
flag may be useful.
With FFFFh the coordination flag is deactivated.
Indicator word
Information concerning the order commissioning may be accessed by the
indicator word. More may be found at "RK512 communication - Indicator
word ANZW".
At proper function, all bits of this bit memory byte are "0". At errors an error
code is entered. The error setting is self-acknowledging, i.e. after
elimination of the error cause, the byte is set back to "0" again. The
following errors may occur:
1 = Data block not present
2 = Data block too short
3 = Data block number outside valid range
These parameters are internally used. They serve the information
exchange between the handling blocks.
