Q: When using the external position setting function block, why can't I instantiate MC_ExtSetPointGenFeed?
A: MC_ExtSetPointGenFeed is a Function, not a Function Block, so it does not require instantiation.
Q: The measurement results of modules such as EP4314, EP4374, and EP4378 are abnormal.
A: For these modules, before configuration and use, it is necessary to check the measurement range set in the module. For specific parameter explanations, please refer to the module manuals.
Manual links: ep4314, ep4374, ep4378
A: Right-click on the function block and select "remove unused FB call parameters".
If there is a need to adjust other pins in the future, use the "update parameters" above to restore.
A: The EL6070 hardware includes 16 system IDs corresponding to different platform levels, but you can only use the system ID and corresponding authorization for a specific platform level in TwinCAT if you have purchased the authorization for that level.
The 16 platform levels are as follows: 20~70 (6 levels), 80~84 (5 levels), and 90~94 (5 levels).
Q: When clicking "Create Bootproject" in TwinCAT2, it automatically performs Sourcecode download.
