Response Format
Parameters Timer/Counter Type (Command)
Designate the timer/counter instruction type for changing the constant SV.
Timer/Counter Number (Command)
Designate in four digits BCD the timer/counter instruction number for chang-
ing the constant SV. (Index register designation is not possible.)
New Constant SV (Command)
Designate the new constant SV in four digits hexadecimal.
Limitations Timers T2048 to T4095 and counters C2048 to C4095 cannot be read.
The command cannot be executed unless the SV is a constant.
If there are multiple relevant instructions in cyclic task 0, a search will be con-
ducted from program address 0, and the first instruction found will be read.
The SV can be changed only in cyclic task 0.
If the SV is a DM or EM indirect address, only indirect BCD designations will
be read and an end code of 16 (command not supported) will be returned if
the indirect designation is not BCD.
