# Well 5a PLC Refresh - Well 5a PLC has an input landed at **I:1/5** labelled **Well 5a High Discharge Pressure **that does not exist in the well25 program. It does not appear to have any affect on controls.  I believe it is only used for alarming.- Well 5a PLC has an input landed at **I:1/6** labelled **Well 5a Low Discharge Pressure **that does not exist in the well25 program. It does not appear to have any affect on controls.  I believe it is only used for alarming.- Well 5a PLC has an input landed at **I:1/11** labelled **Phase Failure **that does not exist in the well25 program. It does not appear to have any affect on controls.  I believe it is only used for alarming or HMI display.- Well 5a PLC has an input landed at **I:1/12** labelled **Desander Valve in Auto **that does not exist in the well25 program. It does not appear to have any affect on controls.  I believe it is only used for alarming or HMI display.- Well 5a PLC has an input landed at **I:1/13** labelled **Waste Valve in Auto **that does not exist in the well25 program. It does not appear to have any affect on controls.  I believe it is only used for alarming or HMI display.- Well 25 PLC has inputs landed at **I:0/3, I:0/4, I:0/5** for UPS status.  Will well 5a also have a UPS that will give us these 3 inputs?- Well 25 PLC has several analog inputs not seen in the well 5a code.  These are seen in the table below.  All of these inputs exist only in the well25 program and none of them are found in the well5a code. | **I:1.0** | 0 | LIT1011 | Level Input | | | | | | --- | --- | --- | --- | --- | --- | --- | --- | | **I:1.1** | 0 | FIT1011 | Discharge Flow | 0.0 to 1000 GPM | Input | | | | **I:1.2** | 0 | PIT1011 | Discharge Pressure | 0.0 to 160.0 Psi | Input | | | | **I:1.3** | 0 | SIT 1001.00 | Pump Speed | 0.0 to 60.0 Hz | Input | | | | **I:2.0** | 0 | TIT1057 | Temperature | 10.0 to 25.0 C | Input | | | | **I:2.1** | 0 | AIT1054 | Turbidity | 0.0 to 1.0 NTU | Input | | | | **I:2.2** | 0 | AIT1056 | pH | 6.0 to 8.0 pH | Input | | | | **I:2.3** | 0 | PDT1011 | Differential Press | 0.0 to 15.0 Psi | Input | | | - And there are two analog outputs in the well 25 program for sending pump speeds to two pumps.  Will well5a have 2 pumps or just one? To-Do During Commissioning- I think the data concentrator sends the stage to the plc via a message. message comm fail rung message comm fail display on HMI
