(Editable only when the Scan Type is set to Fixed Scan.) The scan rate of the scan set. Double-
click the field, then select a value. A value of 0 prevents the I/O from being scanned.
Valid range: 0 through 64.
Default: 1.
(Editable only when the Number of Sweeps is non-zero.) The number of sweeps that the
output scan is delayed after the input scan has occurred. Double-click on field, then select a
value.
Valid range: 0 to (number of Sweeps - 1)
Default: 0.
3.2.12 Power Consumption Parameters
The programming software displays the power consumed by the CPU (in Amps) for each
voltage provided by the power supply.
3.2.13 Access Control
The Access Control List allows you to specify the reference address ranges that can be
accessed by non-local devices such as HMIs and other controllers. To use this feature,
Enhanced Security must be enabled in the properties of the target.
When Enhanced Security mode is enabled, any reference address range not defined
cannot be accessed by other devices. External reads and writes that do not exist in the
table are rejected by the firmware.
If overlapping memory ranges are defined, they must have the same Access level.
For symbolic variables, access control is specified by the Publish property of the variable,
which includes a Read Only and Read/Write setting.
Note: When requesting data from an external device, some drivers packetize data to
optimize communication. If a request attempts to read a value that is not published, the
entire packet will fail. A fault has been added to the fault table to help you understand a
failed read/write. After addressing the fault, you must clear the fault in order to try again.
