The control features an operating data field where so far only 2 entries from
the control are being used. The entries are accessible via the functions
READ_SYSPARAM and WRITE_SYSPARAM.
Index Description
101 Cycle time of a second task (PLC_PRG2) [10 ms]
102 Cycle time of the PLC (PLC_PRG) [ms]
)
Note!
The cycle time of the PLC must be equal to the rough
interpolation cycle (see also machine constant MK_DELTAT).
8.7.8 Reading error messages for the ETCxM
Active error messages can be read for the ETCxM via functional components
of the library "mc.lib". A difference is made between axis−specific errors and
operating system errors. There is one function for reading and one for
acknowledging (resetting) an existing error for each.
