   +----PLCmon.Action

public class Action
extends Object

This constructor creates a data object which contains the instruction and data to be read from or written into the PLC via the ConnectTLServer object

Variable Index

DM: Reference to the DM[n] array to be used for storing READDM data or to be used as the source for WRITEDM action
ID: The ID of the PLC to be accessed, it should be in the range of 00 to FF hex or 0 to 255 decimal.
actionType: Read or Write action represented by ActionConstant.READSINGLE, ActionConstant.WRITESINGLE, ActionConstant.READDM and ActionConstant.WRITEDM
index: Index to the system variable.
result: whether read or write action is successful.
stringValue: String data for WRITESINGLE action or returned String for READSINGLE action
value: Integer data for WRITESINGLE action or returned data for READSINGLE action
varCount: Number of variables to read
varType: Variable type (input, output, DM, timerSV, etc).

Variables

public int[] DM

Reference to the DM[n] array to be used for storing READDM data or to be used as the source for WRITEDM action

public int ID

The ID of the PLC to be accessed, it should be in the range of 00 to FF hex or 0 to 255 decimal.

actionType

public int actionType

Read or Write action represented by ActionConstant.READSINGLE, ActionConstant.WRITESINGLE, ActionConstant.READDM and ActionConstant.WRITEDM

index

public int index

Index to the system variable. E.g. 1 for INPUT[1], 5 for DM[5]. etc. Use character 'A' to 'Z' for Integer and String variables.

result

public int result

whether read or write action is successful.
The result codes are defined in the ActionConstant and would be one of the following:

OK
LOSTSVRERROR
PLCNORESPONSE
CORRUPTEDRESPONSE
ACCESSLEVELVIOLATION
UNSENT
PLCPWDERROR

stringValue

public java.lang.String stringValue

String data for WRITESINGLE action or returned String for READSINGLE action

value

public int value

Integer data for WRITESINGLE action or returned data for READSINGLE action

varCount

public int varCount

Number of variables to read

varType

public int varType

Variable type (input, output, DM, timerSV, etc).
The variable type are defined in the ActionConstant class as follow:

DM
INPUT
OUTPUT
RELAY
TIMER
CTR
TIMERPV
CTRPV
CLK
DATE
HSCPV
ADC
DAC
PWM
RESERVE
EMINT
EMLINT
EMEVENT
INTEGER
STRING
TIMERSV
CTRSV

E.g. Action action = new Action(1, ActionConstant.READSINGLE, ActionConstant.INTEGER, 0, "");
