provide settings for an input reading when ExtendedWrite is “No”, since no input
reading is used.
LocalBaseRegister
This property is visible only when ExtendedWrite is “Yes”, and specifies the local base
register starting the consecutive set of registers to write into the target device. Note: in
the 8310, modbus register nunbers always start at 1 (not 0).
NumRegisters
This property is visible only when ExtendedWrite is “Yes”, and specifies the number of
registers to read locally and write into the target device.
MBDeviceType
Defines the type of communication used to talk to the target device. Possible values are
Serial and TCP/IP. When “Serial”, you also need to select the COMPort configured for
Modbus communications.
COMPort
This property is visible only when MBDeviceType is set to “Serial”. Use this property to
select the COM port configured fro Modbus communications. NOTE: you must configure
the COM port for Modbus using the Station Setup – Communications menu.
TCP/IP Settings
These settings are visible only when MBDeviceType is set to “Tcp”.
The TCP/IP address of the target device
The IP Port to use when connecting to the target device
Enable (turn on) LAN to ensure LAN interface is used for
transactions (as opposed to GPRS or other TCP/IP interface
that might be available; NOTE: the LAN when on, is always
favored)
Timeout
Specifies the time in milliseconds to wait for a response from the target device
Retries
Specifies the number of times to retry a request on failure
SendTime
The SendTime measurement type is special, in that it doesn’t actually measure anything. As
such, this measurement type has no inputs or outputs. The purpose of the SendTime
measurement type is to synchronize the time of another station to the current station’s system
time. The Interval and Time properties determine when the synchronization occurs (just as they
determine when to measure for other measurement types).
When the time specified by the Interval and Time properties is reached, the time of the current
system is sent to the system designated by the “PathURL” property, using an SSP “set-time”
