i.LON SmartServer 2.0 Programmer’s Reference 15-4
Property Description
<InterfaceOptions> This element contains the following options for Modbus
channels attached to the RS-232 or RS-485 serial ports on the
SmartServer (<UCPTchannelType> is CT_RS485_MASTER
or CT_RS232 _MASTER):
• <UCPTspeed>. The baud rate at which the SmartServer
communicates with the Modbus devices on the channel.
The default value is MS_9600. This property may be one
of the following values:
ƒ MS_110
ƒ MS_300
ƒ MS_600
ƒ MS_1200
ƒ MS_2400
ƒ MS_4800
ƒ MS_9600
ƒ MS_19200
ƒ MS_38400
ƒ MS_57600
ƒ MS_115200
• <UCPTsize>. The data bit size for messages sent over the
Modbus network. A data bit is a group of 5 to 8 bits that
represents a single character of data for transmission over
the network. Data bits are preceded by a start bit, and they
are followed by an optional parity bit and one or more stop
bits. The default value is CS_8. This property may be one
of the following values:
ƒ CS_5
ƒ CS_6
ƒ CS_7
ƒ CS_8
• <UCPTparity>. The parity bit size for messages sent over
the Modbus network. A parity bit is an extra bit used to
check for errors in groups of data bits transferred between
devices. The default parity size is P_NONE. This property
may be one of the following values:
ƒ P_NONE
ƒ P_ODD
ƒ P_EVEN
• <UCPTstopBits>. The number of stop bits used on the
Modbus network. The default value is SB_1. This property
may be one of the following values:
ƒ SB_1
ƒ SB_2
This property is not available for TCP/IP Modbus channels.
