Table 2 - Status Byte Binary Weights

Table 2 shows the binary weight of each MCNRCD input line, along with the

name of the input status signal. The binary weights of the four input status signals

are summed to create the

input value

field of the MCNRCD.CFG text definition

line. For your application, all valid combinations of these binary weights must be

defined by separate text definition lines. Table 3 shows the possible combinations

of the binary weights (in the Input Value Field column) and the status name

combination for the value. A column has also been provided for you to enter the

text corresponding to the input value.
