Explanations/operating instructions
Master type
(default value:
Secondary master)
The HART modem uses the serial port of a PC and a HART modem or HART
interface connected to it to communicate with the connected HART devices.
It can be both primary and secondary master.
"Ignore secondary
master" check box
If there is no secondary master, the time behavior can be optimized and
devices can be addressed faster by enabling this option.
"Prefer 'Long address'"
check box
Once a device is known, communication with it is performed only via the long
address. In this case, multiple devices on the same HART modem can have
the short address 0. To make a device known with short address, no other
devices can be connected to the HART modem.
MODBUS
communication
(default value: Serial)
Serial: COM interface must be suitably set for the device. (interface, baud
rate, etc)
IrDA: USB infrared adapter required. The device (1 at a time) then
communicates via this adapter. (multiple USB IR adapters are not
supported.)
Response time*
(default value: 1000 ms)
This is the time waited to obtain a response from a MODBUS device. If this
value is too low, it is possible that no connection to the device will be made.
If it is too high, the communication can be extremely slow.
Subnet ID*
(default value:
0x00000000)
The S7 subnet ID of the network. This parameter is optional - this value is
ignored when configuring via HW Config.
PROFIBUS CP slot*
(default value: 2)
The slot address of the PROFIBUS network. This parameter is optional - this
value is ignored when configuring via HW Config.
DP master address*
(default value: 1)
The address of the hierarchical master on the bus. This parameter is optional
- this value is ignored when configuring via HW Config.
Long address*
(default value:
0x0000000000)
For HART devices, the long address is displayed here.
As soon as the device is known, the long address is stored.
* Entry can be changed.
NOTICE
HART device replacement
For a device replacement, this long address must be set to 0 so that a replacement device
can be newly identified.
The replacement device must be the only device on the HART modem.
The "Redundancy" area is displayed for field devices which are capable of redundant
interconnection.
