Configuring Agilent 1050 and 1100 modules together...

[ChromStud5.0]

Previously, an HPLC was configured as three 1050 modules:
autosampler, pump & VWD. The system was operating with Chemstation
A.10.02. The VWD died and we replaced it with an 1100 G1314
VWD. Just like the old VWD, the G1314 connects via HPIB. We hooked
everything up to the G1314 the way it was connected to the previous
1050 VWD. We went into the GC Chemstation Configuration Editor, it
was selected for modular 3D LC system, and we started by removing the
1050 VWD detector. We noticed there were no specific modules listed
for the 1100, but rather an 1100 System Access option. So, we
selected that and kept the GPIB at address 0. We then tried to
connect to Chemstation, and it asked which 1100 module was connected.
We selected the G1314, it came up as offline after we selected it, and
after several minutes Chemstation loaded. On this first connect, we
were able to communicate with the autosampler and pump, but it stated
there was a power failure with the G1314. We rebooted the software
and G1314, but still couldn't connect. We then went into Visa
Assistant. We can see a bunch of activity listed for GPIB0:16 (1050
pump), GPIB0:18 (1050 autosampler) and GPIB0:24 (INSTR - we assume
this is the G1314). When we open the IO CONFIG, we noticed the serial
number on the 82350 PCI-GPIB card had changed after connecting it to
the G1314. We have tried naming the SICL Interface both hp82341and
hpib7, the visa interface name we have left at GPIB0, logical unit = 7
and Bus Address = 30.

We simply cannot get Chemstation A.10.02 to talk to the G1314 VWD at
all, no matter what we try. It reads offline. And now, it also says
that the 1050 autosampler & 1050 pump have power failure when
Chemstation finally opens.

Do any of you have any thoughts as to what the solution might be? Is it
possible to control an 1100 detector with two 1050 modules in A.10.02
Chemstation? Any advice would be greatly appreciated! Thanks so much!

Yes, you can mix 1050 and 1100 modules in a system with GPIB; we still have one such system.

Previously, an HPLC was configured as three 1050 modules: autosampler, pump & VWD. The system was operating with ChemstationA.10.02. The VWD died and we replaced it with an 1100 G1314
VWD. Just like the old VWD, the G1314 connects via HPIB. We hooked
everything up to the G1314 the way it was connected to the previous
1050 VWD. We went into the GC Chemstation Configuration Editor, it
was selected for modular 3D LC system, and we started by removing the
1050 VWD detector. We noticed there were no specific modules listed
for the 1100, but rather an 1100 System Access option. So, we
selected that and kept the GPIB at address 0.

I'm not sure why you had/have this configured as 3D LC System since you have VWD, not DAD. So I'd change that. In configuration Editor, set up as Modular LC System. Choose 1100 Access, set address code at 24 for 1100 VWD. Then set up the 1050 modules with their address codes (16 for pump, 18 for autosampler). Save the configuration.

When we open the IO CONFIG, we noticed the serial number on the 82350 PCI-GPIB card had changed after connecting it to the G1314. We have tried naming the SICL Interface both hp82341 and
hpib7, the visa interface name we have left at GPIB0, logical unit = 7
and Bus Address = 30.

All I know is to call the interface hp82341 and set the bus address to 30, even with an 82350 board.

Shut off all power to all modules, shut off computer, and start up. If a screen comes up and lists available modules, select the correct ones even ifthey aren't in "green". When ChemStation opens up, if the modules are not communicating (e.g. messages "pump not found", etc.), in Full Menu go under Instrument and see if the modules are listed.

I've even had sometimes to dlete all modules using that menu, then starting up everything and letting the instrument "find" things by itself. I've had to do this up to four times when it gets wigged out.

Thanks for the information! This was the issue and it came online quickly. Thanks again!
