3.9.3 8-3* FC Port Settings
8-30 Protocol
Option: Function:
NOTICE
Further details can be found in the VLT
®
HVAC Drive FC 102 Metasys Operating
Instructions.
Protocol selection for the integrated FC (standard)
Port (RS485) on the control card.
Parameter group 8-7* BACnet is only visible when
[9] FC Option is selected.
[0] FC Communication according to the FC Protocol as
described in the VLT
®
HVAC Drive FC 102 Design
Guide, RS485 Installation and Set-up.
[1] FC MC Same as [0] FC but to be used when
downloading SW to the frequency converter or
uploading dll le (covering information regarding
parameters available in the frequency converter
and their inter-dependencies) to Motion Control
Tool MCT 10 Set-up Software.
[2] Modbus
RTU
Communication according to the Modbus RTU
protocol as described in the VLT
®
HVAC Drive FC
102 Design Guide, RS485 Installation and Set-up.
[3] Metasys
N2
Communication protocol. The N2 software
protocol is designed to be general in nature to
accommodate the unique properties each device
may have. See VLT
®
HVAC Drive Metasys operating
system.
[4] FLN Communication according to the Apogee FLN P1
protocol.
[5] BACnet Communication according to an open data
communications protocol (building automation
and control network), American National Standard
(ANSI/ASHRAE 135-1995).
[9] FC
Option
To be used when a gateway is connected to the
integrated RS485 port, for example the BACnet
gateway.
Following changes take place:
•
Address for the FC port is set to 1, and
parameter 8-31 Address, is now used to
set the address for the gateway on the
network, for example BACnet. See VLT
®
HVAC Drive BACnet Operating Instruction.
•
Baud rate for the FC port is set to a
xed value (115.200 Baud), and
parameter 8-32 Baud Rate, is now used
to set the baud rate for the network
port (for example BACnet) on the
gateway.
[20] LEN
8-31 Address
Range: Function:
Size related* [ 1 - 255 ] Enter the address for the frequency
converter (standard) port.
Valid range: 1–126.
8-32 Baud Rate
Option: Function:
Baud rates 9600, 19200, 38400 and 76800
baud are valid for BACnet only.
The default value depends on the FC Protocol.
[0] 2400 Baud
[1] 4800 Baud
[2] 9600 Baud
[3] 19200 Baud
[4] 38400 Baud
[5] 57600 Baud
[6] 76800 Baud
[7] 115200 Baud
8-33 Parity / Stop Bits
Option: Function:
Parity and stop bits for the protocol
parameter 8-30 Protocol using the FC
port. For some of the protocols, not all
options are visible. Default depends on
the protocol selected.
[0] Even Parity, 1 Stop
Bit
[1] Odd Parity, 1 Stop
Bit
[2] No Parity, 1 Stop
Bit
[3] No Parity, 2 Stop
Bits
8-34 Estimated cycle time
Range: Function:
0 ms* [0 -
1000000 ms]
In noisy environments, the interface may
be blocked due to overload or bad frames.
This parameter species the time between
2 consecutive frames on the network. If the
interface does not detect valid frames in
that time, it ushes the receive buer.
8-35 Minimum Response Delay
Range: Function:
Size related* [ 5 - 10000
ms]
Specify the minimum delay time
between receiving a request and
transmitting a response. This is used
for overcoming modem turnaround
delays.
