Task 1: SCADA Design Services.
ENGINEER shall perform the following additional SCADA design tasks:
1. PLC and HMI control diagrams and design drawings to incorporate three
(3) VFDs, connected to an OWNER -provided and OWNER -
programmed network switch within cabinet PLC -HSP. Three (3) open
Ethernet ports will be required.
2. PLC and HMI control diagrams and design drawings to incorporate one
(1) flow transmitter within cabinet PLC -HSP. The design will include
both power and communications cabling. Hatch will provide an
additional analog UO module in the design if it is required.
3. PLC and HMI control diagrams and design drawings to incorporate
two (2) pressure transmitters within cabinet PLC -HSP. Hatch will
provide an additional analog 1/0 module in the design if it is required.
Task 2: SCADA and EMU Programming Services.
ENGINEER shall perform the following additional SCADA and HMI
Programming Services to incorporate the equipment into the SCADA/HMI

Automatic control will have operator adjustable set -points for
start/stop operation of the plant water pumps. Set points are based
on plant water pressure.
b. PID speed control — each of the VFD speeds will be controlled via
a PID loop within the PLC. The PID loop will vary the VFD
