you could always ask Steve…
looking to start a huber chiller with pilot one controls remotely via the serial interface. can you help me with a strategy?
Yes, I can help you with a strategy for remotely starting a Huber chiller with Pilot ONE controls via the serial interface. Here are the steps you can follow:
- Check the serial interface: Ensure that the serial interface on the Huber chiller is configured and functional. You can check this by connecting to the chiller via a terminal emulator, such as PuTTY, and sending a command to the chiller. If the chiller responds, then the serial interface is working.
- Connect to the chiller remotely: You will need to have remote access to the computer that will be sending commands to the chiller. This can be done through a virtual private network (VPN) or remote desktop connection.
- Send commands to the chiller: Once you have established a remote connection, you can send commands to the chiller via the serial interface. You can do this by sending commands in the appropriate format to the chiller. The format of the commands will depend on the specific model of the Huber chiller you are using. You can refer to the user manual or contact Huber technical support for assistance with the command format.
- Monitor the chiller: Once you have started the chiller remotely, you should monitor it to ensure that it is running properly. You can do this by checking the chiller’s status and any error messages via the serial interface.
- Shut down the chiller: When you are finished using the chiller, you should shut it down properly. You can do this by sending a shutdown command to the chiller via the serial interface.
It is important to note that remote access to the chiller via the serial interface may require additional security measures to prevent unauthorized access. You should consult with your IT department or a cybersecurity expert to ensure that the appropriate measures are in place.
can you be more explicit about using the RS435 interface regarding how to configure communications
Sure, I can provide more explicit instructions on how to configure the RS485 interface for communication with a Huber chiller with Pilot ONE controls. Here are the steps you can follow:
- Connect the RS485 cable: Connect the RS485 cable to the chiller’s RS485 port and to the computer or controller that will be communicating with the chiller. Ensure that the cable is securely connected.
- Check the communication parameters: Ensure that the communication parameters for the RS485 interface are configured correctly. The communication parameters include the baud rate, data bits, parity, and stop bits. These parameters should be set to match the chiller’s default communication settings, which are 9600 baud, 8 data bits, no parity, and 1 stop bit.
- Configure the software: Configure the software that you will be using to communicate with the chiller. This can be a terminal emulator, such as PuTTY, or a custom software program. You will need to configure the software to use the same communication parameters as the chiller.
- Test the communication: Test the communication by sending a command to the chiller using the software. You can send a command to query the chiller’s status, such as “ST?” (without quotes), which should return the chiller’s current status.
- Troubleshoot any communication issues: If you encounter any issues with communication, check the communication parameters and ensure that they are set correctly. Also, check the cable connections to ensure that they are secure. You may also need to consult the chiller’s user manual or contact Huber technical support for further assistance.
It is important to note that the RS485 interface requires termination resistors to be installed at each end of the cable to prevent signal reflections. You should refer to the chiller’s user manual for information on the correct termination resistor values and installation procedures.
I hope this helps! Let me know if you have any further questions.
what command do I send to turn the chiller on?
The command to turn on a Huber chiller with Pilot ONE controls will depend on the specific model of the chiller you are using. However, in general, the command to start the cooling process and turn on the chiller is:
COOL:ON
You can send this command via the serial interface to the chiller using the software you have configured. This command will start the cooling process, and the chiller will begin to lower the temperature of the fluid in the system.
It is important to note that some Huber chillers may have additional safety features, such as a delay before the cooling process starts or an interlock system that prevents the chiller from starting if certain conditions are not met. You should refer to the chiller’s user manual or contact Huber technical support for further information on the specific model of chiller you are using.
Note: this may or may not work.
