6.6.2 FB 406 MC_ReadSysParameter - Reading parameters
Valid for firmware version V3.1.x of the integrated technology
Purpose
• The technology function "MC_ReadSysParameter" returns selected
parameters of a technology object, for example, of an axis or cam.
• The valid actual value is indicated at the restart parameters.
• The result is output at the relevant output parameter, depending on the
parameter type. In this case the other outputs return the a 0 value.
• At input parameter Index you can define which of the multiple parameters of
the project you want to access. Multiple parameters exist in these areas:
- Data records (Dataset_1 to Dataset_16)
- Encoders (Encoder_1 to Encoder_8)
- Synchronization objects (1 for synchronization object, 2 for superimposing
synchronization object)
Applicable to
• The parameter defined by the parameter number and the index must be
available in the system.
