Siemens Simatic S7-1500 / ET 200MP - Writing User-Defined Acyclic Data

Programming
5.1 Programming with STEP 7 (TIA Portal)
Technology module TM FAST (6ES7554-1AA00-0AB0)
36 Equipment Manual, 04/2023, A5E52301130-AA
Status parameter
Error codes or status information are output as word at the Status output.
Code
Meaning Remedy
(W#16#...)
0000
No error.
—
7000
No job in progress.
—
7001
Initialization in progress.
If the initialization takes unexpectedly long
time, check if the Error output of
LTMFAST_ControlREC (Page 31) shows an error.
7002
Reading data record 102.
—
8002
An error has occurred when reading data record 102.
Read the description of the WRREC/RDREC in the
information system of STEP 7 (TIA Portal).
Examples for error codes in the static tag Addi-
tionalErrorID and there remedies:
• 16#DE80E1A0: Activate the TM FAST appli-
cation.
• 16#C080B200: Make sure that the CPU can
access the TM FAST.
5.1.4 LTMFAST_UserWriteREC: Output acyclic data to the TM FAST application
Description
Use the LTMFAST_UserWriteREC instruction to write or read back the user-defined acyclic data
to the TM FAST application in the module.
Operating principle
With a rising edge at the Req input, the instruction writes or reads data record 101 (Page 68).
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.
