7.15.8 Clock comparison (TM=,TM<>,TM>,TM<=,TM<,TM>=)
(c) The following table shows processing details of bits to be compared.
(7) If the data stored in the devices to be compared are not recognized as date data, SM709 will
be turned on after the instruction execution and no-conductive status will be made. Once
SM709 is turned on, on-status will be retained till when the CPU modules are reset or
powered off. Therefore, turn off SM709 if necessary.
Moreover, if the range of devices specified by to +2 or to +2 exceeds the range of
specified devices, SM709 will be turned on and no-conductive status will be made.
(8) The following table shows the comparison operation results for each instruction.
