Python library for ESPEC North America chambers with P-300, SCP-220, Watlow F4, F4T controllers.

chamberconnectlibrary's Issues

Only one connection

Hello!

Can I check that only one user connected to the chamber ?
For example: I connected to chamber and the user from his desctop try to connect to the chamber and set temp. How can i forbid him to working with chamber, when I'm connected and working now.

Thanks!

pip command for 3.6.8 not working

I tried using pip install chamberconnectlibrary-3.6.8 and got this message:

ERROR: Could not find a version that satisfies the requirement chamberconnectlibrary-3.6.8 (from versions: none)
ERROR: No matching distribution found for chamberconnectlibrary-3.6.8

I'm using python 3.9.4 and pip 22.3.1

Does anyone know if there's a problem?

Need support for P-200 controller for SH-242

Is there any support for the P-200 controller that comes embedded into the SH-242 chamber?

On WatlowF4T calling set_operation to rapidly is unpredictable

The F4T needs time to update its current state before a successive call of set_operation start or stop the chamber correctly (when cond_event_toggle was set to False)

Inquire a sample to overwrite a program procedure in SU-262

I met a problem ,when i want to overwrite a program procedure for SU-262 via PC, I already follow the espec program instruction manual, but failed. I can program the fixed temperature mode for SU-262. But I failed in program mode. I doubted the manual has some bug. Please help me.

Another problem using the RS-485

Hi, there is a connection problem again. All parameters on the controller, device manager and in the library are the same. This is probably due to the fact that I use an rs-485 to usb adapter. What could be the problem? Thank you in advance

',' or ';' in P300 program name causes exceptions

As name suggests, fix by updating regular expression

P300/SCP-220 remote programs break program status monitoring.

modify string for espec.get_status so that it starts with 'program' not 'remote'
modify espec.get_prgm_cstime/get_prgm_time to return current status of remote program
modify controllerinterface.sample to correctly handle this state.

In all other cases continue raising the correct exceptions, as they directly request information that is not correct for the this state of the chamber.

Update to Python 3

I was wondering if ESPEC is planning to update this library to python 3 since python 2 will reach its end of life on the 01.01.2020. We as a customer of ESPEC would be very happy if the software interface of our Chamber could stay up to date.
I'm looking forward to your answer.

Wrong file names in chamberconnectlibrary-2.0.2.tar.gz on https://pypi.python.org

In chamberconnectlibrary-2.0.2.tar.gz from https://pypi.python.org files are named in CamelCase style: WatlowF4T.py, P300.py, EspecInteract.py

Because of that, there are some import errors, for example in espec.py:

from chamberconnectlibrary.p300 import P300
...
from chamberconnectlibrary.especinteract import EspecError

In repo on github these files have correct names.

Please repack tar.gz and upload it on https://pypi.python.org

Promblem with connection

Hi! It seems that to connect I need to log in to the client, how can this be done in the console? The error [Errno 10061] appears when connecting. The firewall is disabled, the hosts are the same. The client opens in the browser.

Thank you in advance

Watlow F4T set points don't update in profiles if loops not enabled.

See this issue on EspecWeb for a full description.

Modbus TCP blocking forever

In modbus.py file, class ModbusTCP initialized with "self.socket.setblocking(True)".
I ran into an issue where the interact function hung inside the interact function and I believe it is because it is waiting for one of the socket.recv() calls to come back.
As there is also a lock which prevents from getting into the wrapper upstream, additional calls will not be able to get through causing all communications with the chamber to stop.

How to get allarms info from ARS 220 ?

Hello!
When im working with chamber by you module and i want to get some info about allarms, i have this error:

File "C:\Python27\lib\site-packages\chamberconnectlibrary\controllerinterface.py", line 28, in wrapper
    return func(self, *args, **kwargs)

File "C:\Python27\lib\site-packages\chamberconnectlibrary\controllerinterface.py", line 309, in get_operation
    status = self.get_status(exclusive=False)

File "C:\Python27\lib\site-packages\chamberconnectlibrary\controllerinterface.py", line 40, in wrapper
    return func(self, *args, **kwargs)
File "C:\Python27\lib\site-packages\chamberconnectlibrary\espec.py", line 499, in get_status
    }[self.client.read_mode(True)]

File "C:\Python27\lib\site-packages\chamberconnectlibrary\p300.py", line 320, in read_mode
    return self.ctlr.interact('MODE?%s' % (',DETAIL' if detail else ''))

File "C:\Python27\lib\site-packages\chamberconnectlibrary\especinteract.py", line 72, in interact
    raise EspecError(msg)
chamberconnectlibrary.especinteract.EspecError: EspecError: command:"MODE?,DETAIL" genarated Error:"PARA ERR"

This error occured when i use get_operation().
I use this constructor:

interface_params = {'interface': 'Serial', 'baudrate': COMPORT_BAUD_RATE, 'serialport': comport, 'adr': RS_485_ADDRESS}

controller_type = 'SCP220'

controller = Espec(ctrl_type=controller_type, loops=2, **interface_params)

When i want receive info about allarms, for example: "no water", I use this function:

controller.get_operation()

How can i get info about chamber's allarms ?

On WatlowF4T the get_prgm(0) returns the wrong event type.

Events values on the WatlowF4T are "off"/"nc"/"on" not boolean.
The get_prgm(0) is intended to return a template of sorts, currently the user must convert the False boolean value to a "off" them selves.
