The values must be four-digit BCD in the range 0000 through 9999. Failure
to enter BCD values will not activate the ERR flag. Always set a lower limit
which is less than the corresponding upper limit. MOV(21) is useful in setting
limits. The following ladder diagram shows the use of MOV(21) for setting
limits.
