Axis Operating Input Memory Areas
Section 4-8
The PCU also has an expanded monitoring function that monitors control
information selected from a number of categories, and returns the result to the
Axis Operating Input Memory Areas.
The expanded monitoring function provides two monitors in the Axis Operat-
ing Input Memory Areas (Monitor 1: Words b + 10, b + 11; Monitor 2: Words b
+ 12, b + 13). The information to be monitored by each is selected using Mon-
itor 1 type (Word a + 15, bits 00 to 03) and Monitor 2 type (Word a + 15, bits
04 to 07) in the Axis Operating Output Memory Areas.
