5.1.2 LTMFAST_ControlREC: Update TM FAST application
Description
With the LTMFAST_ControlREC instruction, you manage the TM FAST application in the FPGA
and receive its status information.
Note
Call the LTMFAST_ControlREC
instruction cyclically in OB1 together with the other
instructions you use. The input parameter HWID establishes the connection to the TM
FAST. A
separate instance data block of the instruction is required for each TM FAST.
Startup characteristics
At the first call, the instruction adopts and checks the HWID input parameter.
If startup takes place without errors, the instruction changes to normal operation. In the
event of an error, the instruction does not change to normal operation and generates an
error message.
Operating principle
Data record 100 (Page 63) is either read only or written and then read with a rising edge at
the Req input, depending on the instruction at the Command input. You can only perform a
new job when there is no error pending and no job is active.
