  • Page 95: 8.10 Instructions

    8.10 Instructions  Programming instructions • Since the buffer memory data of the master station is kept transferred (refreshed) to/from the inverters, the TO instruction need not be executed every scan in response to data write or read requests. The execution of the TO instruction every scan does not pose any problem.
