EXPANDED ADDRESS S300 BUS A
The CK721-A version 3.0 firmware release introduces an Expanded Address S300 Bus
feature. This feature increases the number of logical terminals allowed on the S300 bus from
16 to 64. The terminals are addressed Logical Terminal 1 to
Logical Terminal 64.
The CK721-A version 3.0 firmware is backward compatible with Le
gacy Address S300
Bus method, which uses Logical Terminal 1 to Logical Terminal 16.
The following table compares the tw
o addressing modes, including the required module and
firmware version:
