In a Byte, Bit 0 is initially used to assign functions. After the bit 0 the new I/O function is assigned to the next bit.
The remain bits of the bytes will be in NOT USED. When we press Add again new byte is allocated. If bit 8 is
assigned with a function the remaining bits will be NOT USED.
Select the desired function from the dropdown. Modify the configuration settings then save the changes. A new
byte, word or double word will be added to match the length of the new function.
8.1.3.1
Assignable input and output functions
SC controllers contain a 24V DC Input and Output Connector. The following Input/ Output (I/O) functions apply
to the 24V DC I/O connector. There is a maximum of eight inputs and eight outputs for the 24V DC I/O
connector. There is a maximum of 512 bytes of input and 512 bytes of output on each type of Fieldbus used
with the controller (except DeviceNet with a limit of 256 bytes for both inputs and outputs). Ninety-nine is the
maximum number of I/O functions that can be assigned to each Fieldbus input or output. Each I/O function can
have a length of 1 to 32 bits. You must keep track of the lengths for each I/O function you assign to stay within
the maximum length of the Fieldbus you are using. More than one Fieldbus connection can be used at the same
time. For instance, the SC controller can use the 24V DC I/O connector and ModbusTCP on Ethernet and
DeviceNet all at the same time. If more than one type of Input uses a particular function, the controller responds
to an input when a function is asserted on any one of those inputs.
It is important to understand how the SC controller, and the internal PLC, responds to the rising and falling
edges of input functions as they are asserted or removed, not while the levels are high or low. The STOP bit is
an exception; it is a true OR function rather than working off the transition. One type of Input does not have
priority over the other. The controller responds to the first change in status of an input function, no matter which
Fieldbus connection makes the change.
If more than one Fieldbus shares a particular output function, that function is asserted on all shared fieldbuses.
The table below lists the available input and output functions, gives a brief description and indicates the
configuration options for each. The configuration options are an important aspect of the I/O functions, as they
add powerful, multiple dimensions to each function in the controller. These new dimensions allow integration of
the controller in unique ways, providing increased flexibility.
Please see the full description of each function in the section following this table.
