Programming FCs (Functions) and FBs for S7 Ethernet CPs

Explanation of the Formal Parameters

The following table explains the formal parameters for the call interface of the IP_CONFIG function block :

Parameter

Declara-

Type

Possible

Remarks

 

tion

 

Values

 

 

 

 

 

 

ACT

INPUT

BOOL

0,1

When the FB is called with ACT = 1, the DBxx

 

 

 

 

is sent to the CP.

 

 

 

 

If the FB is called with ACT = 0, only the status

 

 

 

 

codes DONE, ERROR and STATUS are

 

 

 

 

updated.

 

 

 

 

 

LADDR

INPUT

WORD

 

Module base address

 

 

 

 

When you configure the CP with STEP 7

 

 

 

 

hardware configuration, the module base

 

 

 

 

address is displayed in the configuration table.

 

 

 

 

Specify this address here.

 

 

 

 

 

CONF_DB

INPUT

ANY

 

The parameter points to the start address of the

 

 

 

 

configuration data area in a data block

 

 

 

 

 

LEN

INPUT

INT

 

Length information in bytes for the configuration

 

 

 

 

data area.

 

 

 

 

 

DONE

OUTPUT

BOOL

0: –

The parameter indicates whether the

 

 

 

1: new data

configuration data area was completely

 

 

 

 

transferred.

 

 

 

 

Remember that it may be necessary to call the

 

 

 

 

FB several times depending on the size of the

 

 

 

 

configuration data area (in several cycles) until

 

 

 

 

the DONE parameter is set to 1 to signal

 

 

 

 

completion of the transfer.

 

 

 

 

For the meaning of this parameter in

 

 

 

 

conjunction with the ERROR and STATUS

 

 

 

 

parameters, refer to the following table.

 

 

 

 

 

ERROR

OUTPUT

BOOL

0: –

Error code

 

 

 

1: error

For the meaning of this parameter in

 

 

 

 

 

 

 

 

conjunction with the NDR and STATUS

 

 

 

 

parameters, refer to the following table.

 

 

 

 

 

STATUS

OUTPUT

WORD

see following

Status code

 

 

 

table

For the meaning of this parameter in

 

 

 

 

 

 

 

 

conjunction with the NDR and ERROR

 

 

 

 

parameters, refer to the following table.

 

 

 

 

 

EXT_Status

OUTPUT

WORD

 

If an error occurs in the execution of a job, the

 

 

 

 

parameter indicates which parameter was

 

 

 

 

detected as the cause of the error in the

 

 

 

 

configuration DB.

 

 

 

 

High byte: Index of the parameter field

 

 

 

 

Low byte: Index of the subfield within the

 

 

 

 

parameter field
