Understanding Discrete Data Transfers 775
When the SLC finishes its program scan, it updates its outputs. If the
GML Commander program is to recognize this new data, the 1394 GMC
Turbo must update its inputs. The SLC update rate depends on the size of
the user's program. The update rate for the 1394 GMC Turbo depends on
the I/O file update rate (see Defining the I/O Configuration) and the servo
update rate (see Enabling M File Transfers). Also, see the SLC 500
Reference Manual (Publication 1747-6.15) for specific programming
instructions.
Transferring Files from the 1394 GMC Turbo to the SLC
To transfer a discrete file from the 1394 to the SLC:
1. Determine the slot in which the 1394 resides. In the following figure,
the 1394 GMC Turbo resides in slot four.
