Output Description

../_images/a0911bcee389c7990a33139000eba54e

RDY

Data_Type Default_Value Range Unit
BOOL - - -

The output RDY indicates that processing of the job currently being processed is completed. This output does not indicate whether processing of the job was successful or not. The output RDY has therefore always to be considered together with the output OK.

RDY = TRUE and OK = TRUE:

Processing of the job is completed without errors. A new job can be started with a FALSE/TRUE edge at input FREI.

RDY = TRUE and OK = FALSE:

During processing of the job an error has been detected. ERR is set to TRUE. A new job can be started with a FALSE/TRUE edge at input FREI.

RDY = FALSE

Processing of an enabled job has not yet been completed (job is still running) or output RDY has been reset with FREI = FALSE.

OK

Data_Type Default_Value Range Unit
BOOL - - -

Output OK indicates whether the job has been handled successfully or whether an error has been detected during processing. In case of an error, OK ist set to FALSE and ERR is set to TRUE. The output OK is not valid until the job has been completed, i. e. if RDY = TRUE.

The following applies:

If RDY = TRUE and

OK = TRUE: The job has been processed successfully.

OK = FALSE: During processing of the job an error has been detected.

ERR

Data_Type Default_Value Range Unit
BOOL - - -

Output ERR indicates whether an error occurred during Function Block processing. This output always has to be considered together with output DONE. If DONE is TRUE and ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.

A1…A7

Data_Type Default_Value Range Unit
BOOL - - -

After completion of job processing, the response is available at the outputs A1 … A7. The number of response parameters depends on the job performed is described below.

List of jobs

Processing a job consists of:

  • transferring the job
  • supplying the OK response or not-OK response

The OK response is described in connection with the corresponding job.

The not-OK response of the individual jobs always looks as follows:

The following basically applies for the not-OK response:

RDY: TRUE

OK: FALSE

ERR:TRUE

A1…A7: 0

Updating of the maximum number of remote modules detected

The input word EW 07,15 contains, amongst other things, the maximum number of remote modules detected in the past. The actual number of remote modules which exist at the moment may be less. This command is used to update this value. The modules which exist are counted and the value is stored. The user can inquire this value in the PLC program (EW 07,15, bit 8…15).

Inquiring the bus configuration

The bus interface of the Master PLC has a list which stores specific data of the remote modules. The remote modules are numbered in this list in the order in which they can be found on the CS31 system bus. The internal number of the modules must be specified with this command. The response to this command is the group number stored under this number and status information on the corresponding module.
