MaxMaster and MA
Note
MaxMaster and MACID affect performing Network communication. It is recommended to set
as small value as possible, and to set the continuous value for MACID. If the values are set as
explained above, efficient Token Passing Configuration is possible because each Master tries to
give Token to Device set as its own (MACD+1).
10.4.3.1.1 BACnet Parameter Setting Details
COM-01
Int485 ST ID (MAC
ID)
Refers to MACID setting parameter used in BACnet. All MACIDs of the
inverter using BACnet must be set before connecting to BUS. MACID
must have the unique value from the Network to be connected to MACID.
If BACnet is used, the value must be within 0–127.
Communication is not available if the value is not included in the range.
Sets the communication speed to use in the network.
Range for Max Master that is the number of devices currently connected
to the communication Line is 1–127, and the default value is 127.
COM-84–85
BAC Dev Inst 1–2
BACnet Device Instance is used to identify BACnet Device, and must be set
as the unique value in the BACnet network. It is used efficiently when
finding BACnet Device of other Devices while installing.
The following formula is used to calculate the Device Instance value:
(COM-84 X 1000) + COM-85
Therefore, in the Device Instance value, COM-84 takes the thousands
and higher places (fourth digit and over) and COM-85 takes the hundreds
and lower places (third digit and below). COM-84 and COM-85 have the
ranges of 0–4194 and 0–999 respectively, because Device Instance can
have the value within 0–4,194,302.
Refers to the password used for Warm/Cold Start. COM-86 Password
parameter can be set within 0–32767, and the default value is 0. If the
parameter setting range is set to 1–32768, the Password value set at
BACnet Master and the value set at COM-86 must be the same to operate
Warm/Cold Start.
If COM-86 Password is set to ‘0’, the password of BACnet Master is
ignored and Warm/Cold Start is operated.
