Stepper Controller

750-670
The Stepper controller RS422 / 24 V / 20 mA 750-670 provides the fieldbus
coupler 12 bytes input and output process image via 1 logical channel. The data to
be sent and received are stored in up to 7 output bytes (D0 ... D6) and 7 input
bytes (D0 ... D6), depending on the operating mode.
Output byte D0 and input byte D0 are reserved and have no function assigned.
One I/O module control and status byte (C0, S0) and 3 application control and
status bytes (C1 ... C3, S1 ... S3) provide the control of the data flow.
Switching between the two process images is conducted through bit 5 in the
control byte (C0 (C0.5). Activation of the mailbox is acknowledged by bit 5 of the
status byte S0 (S0.5).
