Operation/ Adjustment Protection

The relationship between the set values and the range of protection is as shown below.

• When the set value is 0, there is no protective function.

• The initial value is 0.

■

Initial Setting/ Communications Protection

This protect level restricts movement to the initial setting, communications setting, and
advanced function setting levels

.

• Default setting: 1.

■

Setting Change Protection

Places restrictions on changes to settings with keys.

Setting Communications Parameters

Configures the E5EZ-PRR

'

s communications specifications, so that its communications

with the host computer can be configured properly. In a layout where one point communi-
cates with multiple points, in addition to all of the communication unit numbers, all other
settings should match. Each unit must have a single communication unit number set for it.
