Chapter 3 PLC System Configuration & Settings (4) Users will see a strip graph in the block section, with two values on both ends representing the setting range limit. The orange color in the strip graph refers to the existed retentive range; however, when the Block 0 section shows grey content, this means the current section cannot setup retentive range for the selected PLC model. For the setup, users need to input values of the Retentive Range, where the beginning point is the value on the left box and the end point is the value on the right box.
When input values, the beginning point on the left must be smaller than the end point on the right and cannot exceed the strip graph appearing as the range limit. (5) Click Clear to remove the retentive function for the devices in that block and the range values will be from -1 to -1. 3-213
