Method Detail

getIpAddress

String getIpAddress()

Returns:

Get the IP address for this MODBUS IO

getSignalAddress

String getSignalAddress()

Returns:

the signal address for this MODBUS IO

setValue

boolean setValue(int value)

Parameters:

value - Set MODBUS signal to an integer value. If the MODBUS signal is digital, then false is represented by 0 and true are represented by all numbers different from 0.

Returns:

true if the MODBUS signal was sent down to the controller, and false if the signal was not sent down, e.g. because the controller was not running. Notice that the MODBUS signal must support writes, consult the UR MODBUS protocol.

getValue

int getValue()

Returns:

the integer value of the MODBUS signal. If the MODBUS signal is digital then false is represented by 0 and true is represented by the value 1.

isResolvable

boolean isResolvable()

A MODBUS I/O signal cannot be guaranteed to be present in PolyScope. The end user can switch installation or delete the MODBUS signal. This method can be used to determine, if the MODBUS I/O is present.

NOTE: This method cannot be used to check connection status.

Specified by:

isResolvable in interface IO

Returns:

true, if the MODBUS I/O is present in PolyScope. false otherwise.
