VAR_IN_OUT

VAR_IN_OUT
    stParameterBuffer : ST_ParameterBuffer;
END_VAR

stParameterBuffer: Data buffer for the background communication (type: ST_ParameterBuffer).

VAR_INPUT

VAR_INPUT
    iSlaveaddress : BYTE;
    iCounter      : INT;(*1:PhysicalFaultCounter, 2:TimeoutCounter, 3:ResponseCounter, 4:Leave-DataExchCounter, 5:DataExch-FailedCounter *)
    bCounterReset : BOOL;
    bReadLES      : BOOL;(*Read List of all detected Slaves*)
    bReadLAS      : BOOL;(*Read List of all activated Slaves*)
    bStart        : BOOL;
END_VAR

iSlaveaddress: slave address

iCounter: 1:PhysicalFaultCounter, 2:TimeoutCounter, 3:ResponseCounter, 4:Leave-DataExchCounter, 5:DataExch-FailedCounter

bCounterReset: resetting of the current counter.

bReadLES: List of the identified ASI Slaves (LES).

bReadWrite: 0=READ, 1=WRITE.

bReadLAS: List of the activated ASI Slaves (LAS).

bStart: The respective task is carried out via a rising edge at this boolean input.

bCycleMode: 0=continuous reading 1= reading once.

VAR_OUTPUT

VAR_OUTPUT
    bBusy         : BOOL;
    bErr          : BOOL;
    iErrornumber  : DWORD;(* Error code of ASI-Master *)
    iCounterValue : WORD;(*Counter of a slave*)
    iSlaveList    : DWORD;(*LES or LAS of all Slaves*)
END_VAR

bBusy: This output remains TRUE until the block has executed a command. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

bErr: This output shows the error status.

iErrornumber: contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of a command at the inputs.

Command-specific error code (decimal)

Description

1

Communication timeout

2

3 - 10

Reserved

11

ASI slave is not activated (slave is not in LAS)

12

An error occurred during communication.

13

Data exchange bit (CN.4) not set

 

iCountervalue: Counter value.

iSlaveList: LES or LAS.
