Gateway component for EtherNet_IP 23 / 25
Address area Function Access
4098 Status of the other fieldbus Read only
0x00 Fieldbus not connected. Check all
connections
0x01 Fieldbus connected, no data commu-
nication. Check whether an IP ad-
dress is set
0x02 Gateway component configured, no
data communication
0x03 Cyclical data exchange
Input Register
Siemens controllers use 2 predefined address areas. Therefore, the
input and output registers can each be accessed via 2 addresses,
one KUNBUS address and one Siemens address. Both addresses
address the same memory cell, however. No separate address areas
is defined for the input register. Read the holding register with
function code 0x04.
Register area for bit by bit access (coils)
You can also access the input and output data area bit by bit via
coils. The same memory is addressed with the coils as with the
registers.
Example: Coils 1-16 correspond to the bits in register 1,
Coils 17-32 correspond to the bits in register 2.
Address area Use Access Meaning
1 - 3840 Input Bits Read only Values that the other gateway component
supplies.
16385 - 20224 Output Bits Read/write Values that are supplied to the other gateway
component
Discrete Inputs
No separate address area is defined for discrete inputs. Read the
coils with function code 0x02.
