Registers 3 ... 6 save the offset for the bytes in the input process image which are
refreshed using the CAN payload data bytes configured in Register 2. Refreshing
is performed each time a CAN telegram with the corresponding CAN ID is
received. Each register saves the configuration for two CAN payload data bytes.
Register 3 saves the configuration for payload data bytes 0 ... 1.

The structure of Register 4 ... 6 is identical to that of Register 3. Accordingly,
Register 4, 5 and 6 save the configuration for CAN payload data bytes 2 ... 3,

Description
When "Byte refresh" is activated in the
process image (input) for CAN payload data
byte 0: Offset at the point at which the byte
is located that is refreshed using the value
for CAN payload data byte 0.
When "Byte refresh" is activated in the
process image (input) for CAN payload data
byte 1: Offset at the point at which the byte
is located that is refreshed using the value
for CAN payload data byte 1.
