Extended Cyclic Process Image Via Ctt2 - Siemens SIRIUS M200D Manual

5.5.2

Extended cyclic process image via CTT2

Extended cyclic process image of outputs (PIO)
With M200D AS-i Standard motor starters, parameters are transferred from Slave 1 to the
master on a continuous (cyclical) basis. This involves 4 bytes of data. These 4 bytes can be
accessed from the user program in the same way as analog data is accessed.
Transfer from the master to the motor starter (slave) takes place serially via the CTT2
(Combined Transaction Type 2) protocol.
The parameters in the extended cyclic process image can only be used if the extended cyclic
process image has been activated in the configuration (P1=0)
Please refer to the documentation for the AS-i master for detailed information on analog data
transfer.
