Parameter | Name:
C1211 | Subnet mask
Data type: UNSIGNED_32
Index: 23364 = 0x5B44
The IP address ( C1210 ) is superimposed by the subnet mask. The subnet mask serves to identify which part of the
IP address indicates the network and which part represents the device part in the network.
All bits of the network part of the subnetwork mask are set to the value "1 ", and all bits of the device part are set to
the value "0".
A logic AND operation of both binary codes provides information on ...
• the network ID,
• the corresponding network,
• the computer ID.
The TCP/IP protocol is used to determine the path of the message:
• Same network: communication via broadcast
• Other network: communication via router
The standard subnet masks are divided into 3 classes:
• Class A: 255.0.0.0
• Class B: 255.255.0.0
• Class C: 255.255.255.0
Note:
The data are only accepted when the mains has been switched the next time.
The following function is available from version 1.7 onwards!
After the code has been changed, the IP address and subnet mask combination is checked with regard to its validity.
If the IP address and subnet mask combination is invalid, the gateway is set to the IP address 0.0.0.0, and DHCP is
set to dynamic assignment of the IP address (code C1228 ).

Parameter | Name:
C1214 | MAC address
Data type: VISIBLE_STRING
Index: 23361 = 0x5B41
Each communication module has a 48-bit identification, the so-called MAC-ID (Media Access Control). The MAC-ID
is stored non-volatilely in the EEPROM of the communication module.
Basically, the identification of the communication module is allocated by the IEEE (Institute of Electrical and
Electronical Engineers). The IEEE assigns a so-called OUI (Organizationally Unique Identifier) to each manufacturer.
The OUI represents the first 24 bits of the card address. The remaining bits of the address are assigned by the
manufacturer for each card. The numbering of each card must be unique.

Parameter | Name:
C1215 | CAN time-out
Data type: INTEGER_32
Index: 23360 = 0x5B40
By defining a time-out in code C1215, the baud rate (display with code C1209 ) on the CAN bus can be determined.
The baud rate is not checked if the value configured in code C1215 is set to zero.
When the time-out configured in code C1215 elapses, the CAN bus is accessed (for further information and
restriction: see description of code C0351 ).
