Table 6. Values of the PARITY_BITS register
Modbus register 40020;
BACnet object: N/A;
Figure 2. Modbus frame
Note:
The
BACnet protocol requires specific values of stop bits, data bits, and a parity bit
of 1, 8, and none, respectively. Therefore, the user settings for these objects are not
applicable.
REPLAY_DELAY:
determines
a number of milliseconds before the panel answers the
request. This time is used to extend the interval between the request and response. The
default value of 0 means no delay (the response is sent once during the 3,5 character
required by the Modbus RTU protocol).
Modbus register 40021;
BACnet object: N/A.
Incoming data frames are counted and presented through the following parameters:
RECEIVED_FRAMES:
shows the number of received frames. The register's value is reset at
the start of the panel and at the change of transmission parameters;
Modbus register: 30004;
BACnet object: DEVICE, property: 5101;
ERROR_FRAMES:
shows the
number of error messages (shorter than 3 or with incorrect
CRC value) received by the panel from the time of the last power-up. The register's value
is reset at the start of the panel and at the change of transmission parameters;
Modbus register: 30006;

WARNING!
The above parameters are remembered, but NOT automatically set. In order to set
these parameters to the panel, it is required to perform one of the following actions
after entering required values:
restart the panel;
send a reload settings command (0: 0x2FF, DEVICE (property: 3030): 0x2FF, iSMA
Configurator, or FCU Updater).
