- No control of the 515 as a makeup pump in an Autopurification System controlled/configured in MassLynx.
- Cannot control the 515 pump from the inlet method, but the pressure reading is displayed.
- The 515 pump in local mode is able to flow and read pressure.
- That same pressure displays as a readback in the additional status page.
- There is an IEEE cable connected to the GPIB card. National Instruments GPIB driver v2.8.1 is installed.
- The National Instruments Measurement & Automation Devices & Interfaces section and scanned instruments appear to be good.
- When scanning the inlet pump control configuration:
- The pump control module eventually appears, but there is a lag.
- There is no serial number. There is no version. The address shown is 5.
- Can select the PCM@5 as the makeup pump. There is a second 515 pump being used at column dilution.
- When powering-off the 515 pump, a "fatal error Pump@5" message appears.
- Waters Pump Control ICS was removed and reloaded.
- System Fluidics Organizer with Pump Control Module
- 515 Isocratic Pump
The 515 pump defaults back to RUN mode when the SFO is rebooted.
- The 515 loses communication with the PCM temporarily when either pump or PCM power is cycled.
FIX or WORKAROUND
- In order to work with software control, the 515 pump must be placed in Remote/Run mode from the front panel of the pump.
- This needs to be done each time the pump is powered-on or when communications to the PCM are lost.
- The upper-right area of the pump display alternates between REM and RUN when the pump is in the correct mode.
Confirmation of communication with the PCM:
- Shut down MassLynx and run the StopMassLynxProcesses.cmd from the "C:\Program Files\Waters Instruments\Bin\" folder (this ensures that nothing is running in the background and saves a reboot).
- Start the National Instruments Measurement & Automation program.
- Open the Devices & Interfaces section.
- Right-click on GPIB0 and select Scan for Instruments.
- Multiple instruments are listed with a PAD of 5. These are the PCM. If you see this, the GPIB is working and the cabling to the PCM is OK.
- Close Measurement & Automation.
