Vibration Velocity/Bearing Condition Monitoring VIB I/O
750-645
The Vibration Velocity/Bearing Condition Monitoring VIB I/O has a total of
12 bytes of user data in both the Input and Output Process Image (8 bytes of
module data and 4 bytes of control/status). The following table illustrates the
Input and Output Process Image, which have 12 bytes mapped into each im-
age.

These modules present themselves with 4x3 bytes, so that the object 0x2600
for 3 byte Special Modules, Inputs and the object 0x2700 for 3 byte Special
Modules, Outputs are used. Therefore for each logical channel one Subindex
is occupied.
AS-interface Master Module
750-655
The maximum process image of the AS-interface master comprises 48 bytes.
When using a CANopen coupler / controller, the maximum mailbox size is
limited to six bytes.
Each PDO can hold 8 bytes of data.
The first PDO, which is assigned to an AS-interface master module, contains
the status / control byte, one empty byte and up to six bytes of mailbox or
process data. The subsequent PDOs contain AS-interface process data.
