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

).
