Digital Pulse Interface module
750-635,
753-635
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.

15.1.5.9 DC-Drive Controller
750-636, -636/000-700, -636/000-800
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.
