14.4 Limit Objects (Byte, Word, Dword)
Limit Objects have a fixed range and come in three sizes:
•Byte
8 bits
•Word
16 bits
•Dword
32 bits
Limit Objects are handled differently depending on the direction of the transaction:
• Produce/Query Transactions
This object shall not be used for such transactions (value will be undefined).
• Consume/Response Transactions
The gateway will check if the received byte/word/dword fits inside the specified boundaries. If
not, the message will be discarded.
There are 3 types of interval objects:
•Byte
8 bit interval
•Word
16 bit interval
•Dword
32 bit interval
To set the range of the object, select it in the Navigation Section and enter the desired range in the Pa-
rameter section as follows:
Parameter Description
Maximum Value This is the largest allowed value for the range.
Range:0x00 to 0xFFh(byte)
0x0000 to 0xFFFFh(word)
0x00000000 to 0xFFFFFFFFh(dword)
Note: The value must be larger than the Minimum Value.
Minimum Value This is the smallest allowed value for the range.
Range:0x00 to 0xFEh(byte)
0x0000 to 0xFFFEh(word)
0x00000000 to 0xFFFFFFFEh(dword)
Note: The value must be less than the Maximum Value.
