Limitations Bits in SR 253 through SR 255 can’t be specified.
Only 15 timers/counters or 15 Transition Flags can be set/reset.
The UM settings are not checked when Transition Flags are specified, i.e., as
long as the Transition Flag address does not exceed 1023, the command will be
executed normally even if the specified Flag does not actually exist in the remote
PC.

cancel data can be one byte long or 16 bytes long.)
An end code of 15 (entry number data error) will be returned if the operand, word
address, or bit parameter setting is incorrect. An end code of 15 will also be re-
turned if the a data specification of 0 or 1 is used for a timer or counter Comple-
tion Flag or for a Transition Flag.
An error code of 15 (entry number data error) will be returned if [$C, $D] is speci-
fied for the forced data when set to TC.
