This guide shows how to use the information in Appendix A to control a pump remotely from a PLC. The steps
progress from basic pump control to more advanced monitoring and alarm control features.
It is important that you first follow all directions in the
Setup Screens to configure your system properly.
Test that the pump operates correctly when controlled
from the Display. Make sure the display, fiber optics,
communication gateway, and PLC are connected
properly. Refer to Communication KIt manual. Use
Setup Screen 12 to enable remote control and set
your modbus preferences.
