XUDC3000: Honeywell UDC 3000 Universal Digital Controllers Driver v10.0

XUDC3000: Honeywell UDC 3000 Universal Digital Controllers Driver

General Information:

XUDC3000 driver allows you to connect to the HONEYWELL UDC3000, UDC5000 and UDC6000 controllers. The protocol uses is the ASCII protocol, not the DMCS protocol, and the controller must be configured for RS-422/485.

Pin assignment should be:
  • UDC3000 pin 7 ------> TX+/RX+ in the PC or converter

  • UDC3000 pin 8 ------> TX-/RX- in the PC or converter

  • If you cannot communicate or if you are using RS-485 to connect to the device, you should set the RTS signal during the communication. This can be done by setting the RTSEnable argument when calling the read and write methods. If you still cannot communicate, check that your RS-485 cables are not inverted.

    This driver was developed according to the information contained in the 'Product Manual UDC 3000 RS-422/485 Communications Option' version 51-51-25-08 12/88. Some differences where detected in the protocol actually used by the controller with which tests where made. This controller was an UDC 3000 model DC3004-0-40A-2-00-0111. Using this driver with different models could cause some errors, such as timeout errors.

    Important note:

    A delay may appear when changing some data in the controller, such as SetPoint #1 that can take over 30 seconds to be acknowledged.
