operating at the same time. An error will occur in the program check if the
same timer number is used in more than one timer instruction.
An error will occur and the Error Flag will turn ON if an indirect IR designation
is used for N in BCD mode and the address is not for a timer present value or
if SV is not BCD.
The timer will not operate correctly if the cycle time is 100 ms or longer.
In the following example, "B" will be executed 20 seconds after "A" whenever
CIO 000000 is ON.
