The above Digital Pulse Interface module has a total of 4 bytes of user data in
both the Input and Output Process Image (3 bytes of module data and 1 byte of
control/status). The following table illustrates the Input and Output Process
Image, which have 2 words mapped into each image. Word alignment is applied.

DC-Drive Controller

750-636
The DC-Drive Controller maps 6 bytes into both the input and output process
image. The data sent and received are stored in up to 4 input and output bytes
(D0 ... D3). Two control bytes (C0, C1) and two status bytes (S0/S1) are used to
control the I/O module and the drive.
In addition to the position data in the input process image (D0 ... D3), it is
possible to display extended status information (S2 ... S5). Then the three control
bytes (C1 ... C3) and status bytes (S1 ... S3) are used to control the data flow.
Bit 3 of control byte C1 (C1.3) is used to switch between the process data and
the extended status bytes in the input process image (Extended Info_ON). Bit 3
of status byte S1 (S1.3) is used to acknowledge the switching process.
