If the instrument is busy carrying out the sweep, then the VISA write of the "*OPC?" command is not processed until the sweep completes.  This is why the VISA read will timeout.

An alternate approach is to use VISA's ReadSTB() to obtain the value of the status byte or status.condition register.

I put an elaboration and Python sample in the attached document.

Hello,
The PDF is too large for attaching, so here is link to Box:

Reference Manual for the original 2600 models

The LAN communication can be applied from your router (DHCP) or selected manually.

Sounds like you have been using DHCP and the router is periodically giving new address?

Perhaps you can reserve an address in the router setup and manually configure the instrument to use it?

Appendix B-2 in the 2400 Series User Manual has the error codes.
NOTE:  this is not the touch screen models (2450, etc).

User Manual for 2400 Series SourceMeter

Some general comments:

For switching pA levels, consider the offset current spec of the switch.

For parallel reliability testing, consider using a power supply to apply voltage bias to N devices.
And then switch in a sensitive amp meter one by one.
When not measuring the current, the switching scheme needs to maintain pathway completion for the current to flow.
Model 3761 switch is one example.

KickStart does not use tsp-link for communication with the SMU.
KickStart needs a computer connection to each SMU (lan, usb or gpib).

If you additionally have tsp-link between the instruments, KickStart can use that for their triggering/coordination.
 

The 4.x firmware of 2600B series apply only to units shipped from factory with a 4.x level.

If your 2600B has 3.x level, then 3.4.2 from Tek.com would be the most recent version.

Here is a lightly edited version of your code:

Hello,

You are almost there.

To accomplish the phase shift, were you thinking to use a different timer for each SMU?
Instead, I would use a single timer to provide the smuX.trigger.source.stimulus to each SMU channel.

Rather than providing a list of source levels, I recommend computing them. in the TSP or Lua code.
You can account for the phase shift in the computed source levels.

   
   -- compute the sine wave
    pts_per_cycle = 72
    wfrmTbl = {}
    for i=1, pts_per_cycle do
        wfrmTbl[i] = 1 * math.sin(i * 2 * math.pi/pts_per_cycle)
    end
    
    -- use some phase shift for smub sine wave
    wfrmTbl_smub = {}
    for i=1, pts_per_cycle do
        wfrmTbl_smub[i] = 1 * math.sin(i * 2 * math.pi/pts_per_cycle + math.rad(90))
    end

You second task can be implemented with the asynchronous trigger model.

Old forum showing the feature:
asynchronous sampling from the source timing - capture transients

I will upload a simple LabVIEW sample for loading scripts/functions and then making use of the functions from VIs.
