Figure 73 - Example Ladder Logic to Write Multiple Parameters
Important: If the explicit message scattered write must be written
continuously, then use a separate Generic Set service explicit
message single write for each parameter using DPI Parameter
Object Class code 0x93 and attribute A (10 decimal; see
page 133 ). Attribute A writes to RAM—not NVS (EEPROM)
memory. This example scattered write message using attribute 0
writes to NVS. Over time, continuous writes will exceed the
EEPROM life cycle and cause the drive to malfunction.
