98 Transmitter Configuration and Use: Series 1000 and 2000 Transmitters
Optional Configuration continued
To enable RS-485 communications with the transmitter from a remote device:
1. Set the transmitter’s digital communications parameters appropriately for your network.
2. Configure the remote device to use the specified parameters.
Note: Changing the RS-485 communication settings does not affect service port connections. Service
port connections always use default settings.
Note: In some versions of ProLink II, a button named
Choose Typical HART Settings is provided.
When this button is pressed, the settings for the RS-485 terminals are changed to the most common
settings used for HART communications:
• Protocol: HART
• Parity: Odd
• Baud Rate: 1200
• Stop Bits: 1
Note the following when setting RS-485 parameters:
• If HART protocol is selected, setting the address to any number other than 0 automatically
fixes the mA output at 4 mA. To allow the mA output to vary with the assigned process
variable, this address must be set to 0.
• If you are using ProLink II, and you are connected to the transmitter over a Modbus RS-485
connection, ProLink II will lose communication as soon as you click the
Apply button. To
reestablish communication, you must change the ProLink II communication settings to match
the settings configured in the transmitter.
• If you are using the display:
- And the off-line menu has been disabled, you will not be able to change the RS-485
options with the display. For information about enabling and disabling the off-line menu,
see Section 8.14.1.
- The address item allows users to enter the polling address. Valid addresses depend on the
protocol selected earlier. Valid addresses for Modbus protocol must be in one of the
following ranges: 1–15, 32–47, 64–79, or 96–110. Valid addresses for HART protocol
must be in the range 0–15. If Protocol is set to
NONE, the address item will not appear.
