Monitor
of words
(Note-1): Subcommand is for the QnA-compatible 3E frame.
(Note-2): Devices such as TS, TC, SS, SC, CS, and CC cannot be specified in units of words.
For the monitor registration, an error (4032H) occurs during the monitor operation.
(Note-3): During monitor registration, monitor condition cannot be set.
(Note-4): Do not execute monitor registration from multiple external devices. If executed, the last monitor registration becomes valid.
(Note-5): Set the number of processed points so that the following condition is satisfied.
(Number of word access points)
• Bit devices are regarded as 16 bits during word access and 32 bits during double-word access.
• Word devices are regarded as one word during word access and two words during double-word access.
(2) Command list
When the PERIPHERAL I/F of the Motion controller communicates using the MC
protocol, commands listed in table below can be executed.
