20 Micro Motion Series 1000 and Series 2000 Transmitters
Connecting with ProLink II or Pocket ProLink Software
10. If an error message appears:
a. Swap the leads and try again.
b. You may be using incorrect connection parameters.
- Ensure you are using the correct COM port.
- Connect using the service port and check the RS-485 configuration. If required,
change the configuration or change your RS-485 connection parameters to match the
existing configuration.
- If you are unsure of the transmitter’s address. use the
Poll button in the Connect
window to return a list of all devices on the network.
- Check all the wiring between the PC and the network. You may need to add resistance.
See Figure 3-3.
3.4.3 Connecting to the primary mA output terminals or to a HART multidrop network
To connect a PC to the primary mA output terminals or to a HART multidrop network:
1. If you are connecting to an AN or CIO transmitter, see Figure 3-4. If you are connecting to an
IS transmitter, see Figure 3-5.
2. Attach the HART interface to the serial or USB port of your PC.
3. To connect to the primary mA output terminals, open the cover to the intrinsically safe wiring
compartment and connect the HART interface leads to the terminals labeled
1 and 2, or to the
output wires from these terminals.
4. To connect to a HART multidrop network, connect the HART interface leads to any point on
the network.
Connecting a HART device to the transmitter’s primary mA output terminals
could cause transmitter output error.
If the primary mA output is being used for flow control, connecting a HART device
to the output loop could cause the transmitter’s 4–20 mA output to change, which
would affect flow control devices.
Set control devices for manual operation before connecting a HART device to the
transmitter’s primary mA output loop.
