MultiCONT detects devices in accordance to the
Short address
(that is why two or more devices must not have the same Short address)
After detection however, query will be performed using the
Long address
that consists of the following three parts:
Manufacturer’s ID:
(See APPENDIX 1. At the end of the Manual (for NIVELCO products it is:151)
Device type ID:
identification number of the device type (see chapter 5.2.1.1)
Device ID:
number generated during production (0…16777215)
When detection stops with the „
Same Long address”
error message there are two ways to identify the devices with the same Long address
Devices should be removed one by one until
DEV detect
program can run to completion.
Obviously the address of one of those devices remained in the loop is the same as the address of the unit last removed.
Then reconnecting the devices one by one again, after detection, the Factory ID, Device Type ID, and Device ID can be read in from the “Main
menu”/”Devices” menu item (see chapter 5.5 programming devices)
The Long addresses of the transmitters can be read using the Eview configuration software (preset to work with Short Addresses) provided with HART capable
devices
Since the
Long address
can not be modified please send such a unit back to the manufacturer, or call our Export Sales Department for help.
Question: what happens if the MultiCONT does not find all the devices?
1.
One of the transmitters is not HART-capable. Check the transmitter type on the name plate.
2.
Faulty device. Dismount the unit and check it in laboratory circumstances
.
3.
Faulty wiring connection.
4.
The terminal voltage of the unit is small, check the configuration of the current outputs of the transmitters (See chapter 5.2.1.1 preparation of transmitters)
5.
None of the devices are responding, please check:
Is there any voltage between terminals L+ and SH? If no, then the output is faulty, or there is a short-circuit on the line.
If there is voltage between terminals L+ and SH, then check if the terminals L+ and L- are short-circuited or if there is an open-circuit.
Then, the next steps will be
adding the device to the list, and setting the device.
