12-4 Entering MicroView Configuration Data
MicroView Advisor The Advisor function allows screen changes to be made by the logic
controller. The advisor consists of a controller address monitored by
the MicroView. When the advisor address contains a screen number,
the corresponding screen is displayed.
When you select MicroView Advisor from the Configuration – Option
Selection menu, the following is displayed:
The MicroView Advisor consists of six items:
Item Purpose
Screen Read
Register Number The controller address (16 bit) that the
MicroView reads for the current screen number.
ACK/NAK Write
Register Number The controller address (16 bit or bit type) that
contains the ACK
and NAK bits which are written to and monitored
by the MicroView
and controller. The write register is updated at
the Update Interval not the Advisor update rate.
ACK Bit* The bit number within the ACK/NAK write
register that will be used as an
acknowledgement bit. If a bit type address was
assigned for the write register, this field will be
filled in using the bit address specified. ACK/
NAK bits are used only to indicate that the
MicroView has received a message.
ACK/NAK Bit Polarity Defines the polarity (0 or 1) ACK/NAK bits:
When set to 1, a value of 1 for the ACK bit
indicates a valid screen and a value of 1 for the
NAK bit indicates an invalid number.
When set to 0, a value of 0 for the ACK bit
indicates a valid screen and a value of 0 for the
NAK bit indicates an invalid number.
Screen Write Enable ** When enabled, the MicroView writes the current
screen number to the controller.
Screen Write
Register Number The controller address that is written by the
MicroView when screen write is enabled. The
MicroView writes the current screen number in
this register.
* NAK bit is always the next sequential bit after the ACK bit.
** If Mode Menu is the current screen, the MicroView assigns it to screen number 255.
