B - 3
S6
Specification S6 is the block address of the first digital output
subscriber (function code 188).
S9
Specification S9 is not used; it must be set to 1.
S10
Specification S10 defines the first two high order bytes of the
PLC device IP address. The IP address is in the format:
xxx.xxx.yyy.yyy
The specification is set to a decimal value derived from the
binary equivalent of xxx.xxx. If the decimal value is greater
than the specification range, subtract 65,536 from the value
and enter the negative result.
Example
IP address = 151.89.202.127. The first two bytes (151.89) convert to a binary
equivalent of:
100101111011001
The decimal equivalent is 38,745 which is greater than 32,767. In this case
the value to enter in S10 is 32,767 – 65,536 = –26,791.
NOTE: The limits for class B and C networks are as follows:
B = 191.255.yyy.yyy (49,151 – 65,536 = –16,385)
C = 223.255.yyy.yyy (57,343 – 65,536 = –8,193)
