2.7
0x0
Refreshing of a byte in the process image
(input) using the value for CAN payload
data byte 7 activated.
0x1
Refreshing of a byte in the process image
(input) using the value for CAN payload
data byte 7 deactivated.
2.8 … 2.15 0x0
Reserved
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.

Value range /
Possible values
Description
3.0 … 3.7
0x00 ... 0x2F
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.
3.8 … 3.15 0x00 ... 0x2F
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.
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,
4 … 5 and 6 … 7.
