2.5 Power Up and Synchronization with the User Program
The TaskStartInfo contains the logical address of the relevant module.
TSI#logDiagAdr, TSI#details, TSI#eventClass, and TSI#faultId are irrelevant for TM15/TM17
High Feature Terminal Modules.
For additional information on the TaskStartInfo, refer to the "SIMOTION ST Structured Text"
Manual.
2.5.2
Monitoring synchronization by direct access to the module status word
The synchronization of the TM1x terminal modules is displayed cyclically to the SIMOTION
motion control system via the module status word.
The module status word address corresponds to the input address of the module. A WORD
variable must be created for the module status word.
The synchronization bit SYNC is located in bit 8 of the module status word:
Bit
Function
"-" means reserved, cannot be used
Synchronization bit (bit 8):
SYNC = 0 →
SYNC = 1 →
If you want to monitor the synchronization using I/O accesses, we recommend that you
either configure an input WORD variable on the TM1x module status word with "substitute
value=0" or perform the access by means of the secured getSafeValue system function.
The user program must always use a WORD variable to access the status word (individual
bits must be isolated by masking).
As soon as SYNC bit = 1, the module is synchronized and may be accessed directly by I/O
or technology objects.
