DECSCONTROL IN FCR MODE and so on. The three highest bits in this instance are unused and thus
always return a value of zero.

Table 36 shows the bit number of each parameter in instance 8 and an example packet returned from a
DECS-250. Reading a value of 0x02 (0000 0010) for instance 8 indicates that the device is operating in
FCR mode.

Example 2: Bit Packing Order for Instance 11
The total size of Instance 11 is two bytes. Table 37 shows the parameters of instance 11 as they appear
in Table 39. The first parameter in instance 11, with key name CONTACTOUTPUTS
WATCHDOGOUTPUT, is represented by the lowest bit in the first byte (bit 0). The ninth parameter, with
key name CONTACTOUTPUTS OUTPUT8, is represented by the lowest bit in the second byte (bit 0).
The four highest bits in the second byte are unused and thus always return a value of zero.
