Re: Some questions about CaLab (Dariush Hampai)

[Dariush Hampai via Tech-talk <tech-talk at aps.anl.gov>]

Hi Carsten,
this means that if I send a CaLab get.vi with PV mm4006:m11 and the array field [HOMF,MOVN] I receive an array of value [12,24]... is it right?

The second question is more important... in someway even using disconnect all PV (or sending directly the names of PV to disconnect), with CaLab Info.vi I have in back all the PVs.
Is it possible that the problem is with the architecture of Labview? i.e., Labview64 or Labview32?

Awaiting your replay

The CA Lab does not have a function for writing multiple fields in a single channel access command.

Fields are written by adding the field name with a dot.

If you need to write to multiple fields, you can use array parameters as follows:

Mark -

It looks like the issue may be that the VID/PID pair (particularly the PID) may not be included in the currently running ftdi_sio driver.

A quick Google search turned up this incantation, which may be helpful:


echo "<VID> <PID>" >  /sys/bus/usb-serial/drivers/ftdi_sio/new_id

Untested, as I?m out of the office, but hopefully this may point you in the correct direction.

Hi Mark!

I suppose the problem is in product's ID.

Newport-CONEX-AGP's "idProduct=3006" *is* listed among supported IDs in 
ftdi_sio_ids.h, see https://urldefense.us/v3/__https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/usb/serial/ftdi_sio_ids.h?h=v6.16-rc2__;!!G_uCfscf7eWS!cEIzCUjhW53L-KKEAV3e3SDEZCubl_LXE7ev4lxhWZfS5l5_fb1Uvx73nAo1Qmei1z1rHE3YjXYUZg_-sksd1QU4UU-cxedRxvU$ 

#define NEWPORT_CONEX_AGP_PID		0x3006

(and in ftdi_sio.c driver too)

while CONEX-AGAP's "idProduct=3008" is not, even in the latest kernel 
version 6.16 (AFAIR, RHEL9 uses Linux kernet 5.14).


With best regards,
Dmitry

Folks,

I have an older Newport-CONEX-AGP controller that works fine on Linux.

The device has a USB interface and uses FTDI.  When I plug in the device on my RHEL 9 machine I see these messages in dmesg:

[62289.315988] usb 1-4: new full-speed USB device number 10 using xhci_hcd

[62289.451085] usb 1-4: FTDI USB Serial Device converter now attached to ttyUSB0

The device is now available on /dev/ttyUSB0.

I expected to be able to do the same thing with a newer CONEX-AGAP controller.
https://urldefense.us/v3/__https://www.newport.com/f/conex-piezo-absolute-positioning-mirror-mount__;!!G_uCfscf7eWS!esBpnKdccckn_TlnsWE5ruJncpjWNfxHfi8SNZ2M5qWp8ab4wjlgsB18EO_4YOzuwREd1qW6ipequMg2cHFG2VO-mdQ$

However, when I plug in the device on my RHEL 9 machine I see these messages in dmesg:

[62360.327898] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[62360.327934] ftdi_sio 1-4:1.0: device disconnected

[62363.655978] usb 1-4: Product: CONEX-AGAP
[62363.655980] usb 1-4: Manufacturer: Newport
[62363.655982] usb 1-4: SerialNumber: A694ND5H

Note that I do not get the messages about ftdi_sio detected or the message about attaching to ttyUSBx.

The new CONEX-AGAP works fine on Windows, where it appears as a COM port.  I can configure the COM port with EPICS:

drvAsynSerialPortConfigure("serial1", "COM5", 0, 0, 0)
asynOctetSetInputEos("serial1",0,"\r\n")
asynOctetSetOutputEos("serial1",0,"\r\n")
asynSetOption("serial1",0,"baud","921600")
asynSetOption("serial1",0,"bits","8")
asynSetOption("serial1",0,"stop","1")
asynSetOption("serial1",0,"parity","none")
asynSetOption("serial1",0,"clocal","Y")
asynSetOption("serial1",0,"crtscts","N")

Given the behavior on Windows, I think the CONEX-AGAP is also an FTDI device.  But if so, then why is Linux not recognizing it as such?

Thanks,
Mark

Hi all,
I have some problems with CaLab, necessary to integrate epics with a 
LabView interface. In particular now I have two big problems:
1) i don't understand how to use multiple field in the same CA. For 
example, my newport IOC includes some records of the type
mm4006:m11.HOMF
mm4006:m11.MOVN
etc...
CaLab Put.vi does not include the field. What do I do? if I put (for 
example) mm4006:m11.HOMF and mm4006:m11.MOVN as PV I find two distinct 
PVs...
2) I am trying to generate a monitor of the various IOCs. When starting 
LabView there is no PV (via CaLab info.vi). If I start the IOCs I see 
the PVs. However if I stop the IOCs, via command prompt (caget etc...) I 
do not see (obviously) the active CA, while via CaLab info.vi the CA are 
still active and give me the last values read. Even after a reset of PV, 
using CaLab_Disconnect.vi, I still see the active CAs with the last 
value read. Where am I going wrong?
