Function library LenzeIOSystem.lib

Function blocks

4.1 L_IOParComGuarding − Monitoring function

4−3

LenzeIOSystem.lib EN 1.7

(Variable type: VAR_INPUT)ð Inputs

Variable name Information/possible settingsData type

tHeartbeatProducerTime Time Set the transmission time for one heartbeat telegram t = 0 − 65535ms

byErrorBehavior Byte Set the bus status / behaviour on critical device error

0 Pre−Operational (default)

1 No status change

2 Stop

3 Reset after 2 seconds

tTimeOutPDO1_DataToIO

...

tTimeOutPDO10_DataToIO

Time Monitoring period for process input data (Lenze−specific).

If no data are received at the selected PDO within the monitoring period, the I/O

system assumes the status set under byErrorBehavior.

Default t = 0 ms

t = 0 − 65535 ms

tTimeOutPDO1_DataFromIO

...

tTimeOutPDO10_DataFromIO

Time Monitoring period for process output data.

If no data are transmitted from the I/O system to the PLC at the selected PDO within

the monitoring period, function block L_IODataXXX signals a time monitoring error.

Default t = 0 ms

t = 0 − 65535 ms

Outputs ð (Variable type: VAR_OUTPUT)

Identifier Data type Value/meaning

nState Integer States

If a transmission error occurs during the parameterisation process, or the input data

are incorrect, the parameterisation process is aborted and an error number is

indicated at output nState.

Any errors are reset via an edge reversal at input bExecute or on program restart.

0 Transmit command is executed.

1 Transmit command sent − processing in process

2001 Error occurred during bus transfer

2002 Transmit command timed out

2004 Access denied − wrong target system: Subindex does not exist

2005 Access denied − wrong target system: Index does not exist

2013 Access denied − wrong target system: Invalid value range

2111 Access denied − wrong target system: More than 4 digits

specified after comma, or no fixed−comma−format index

2117 Communication channel does not exist − also refer Set byCom

channel

2120 Too many modules connected − parameter transfer aborted

−10xx Incorrect value at function block input.

XX := Number of faulty input (counting direction down),

parameterisation impossible.

Remedy: Change input value, restart data transmission
