5.1 Programming with STEP 7 (TIA Portal)
Technology module TM FAST (6ES7554-1AA00-0AB0)
Equipment Manual, 04/2023, A5E52301130-AA
39
Operating principle
The input parameters UserlogicDB and FilenameSMC are adopted with a rising edge at the
Req input. If you load the TM FAST application from an upd file, FilenameSMC must contain
the name of the upd file and UserlogicDB = 0. If you load the TM FAST application from a data
block, UserlogicDB must contain the number of the data block.
You can only perform a new job when there is no error pending and no job is active.
You can find an example for the reaction of the Busy, Done and Error bits in the section
LTMFAST_ControlREC: Update TM FAST application (Page 31),
Reaction to error
The Error output indicates whether an error has occurred in the running cycle. In the event of
an error, the error code is displayed at the Status output.
Parameter
The following table shows the parameters of the instruction.
Parameter Decla-
Data type Default Description
Starts the job at a positive edge.
1
Hardware identifier for module from hardware configuration
Name of the upd file that is to be loaded from the "UserFiles" sub-
folder of the SIMATIC Memory Card. The name must not contain any
special characters or spaces.
If you load an upd file from the SIMATIC Memory Card, Us-
erlogicDB = 0 is required.
Done = True is displayed for one cycle or until Req is reset: The job
was completed without errors.
Busy = True: The job has not yet been completed.
Error = True is displayed for one cycle or until Req is reset: An error
has occurred. In this case, Busy and Done are set to False. For de-
tailed information, see Status parameter.
Status of the instruction, displayed for one cycle or until Req is reset:
