Description

Function description

This function block supplies the I/O module signals immediately during processing. The output module must be in the local rack of the PLC.

and can be configured as additional parameters.

Parameter description

Description of the input parameters:

Parameter	Data type	Meaning
RACK	INT	Rack number (Quantum: 1)
SLOT	INT	Slot number (Quantum: 1...16)

Description of the output parameters:

Parameter	Data type	Meaning
STATUS	WORD	Status report

Runtime error

The ENO parameter can be used for error display:

ENO	Meaning
1	Operation OK (STATUS equals "0")
0	Operation faulty (STATUS equals "0")

EN stands for ENable; it is an optional block input. When the EN input is enabled, an ENO output is set automatically.

If EN = 0, the block is not enabled; its internal program is not executed, and ENO is set to 0.

If EN = 1, the block's internal program is run and ENO is set to 1. If an error occurs, ENO is set to 0.

If the EN input is not connected, it is set automatically to 1.

ENO

ENO stands for Error NOtification; this is the output associated with the optional input EN.

If ENO is set to 0 (because EN = 0 or in case of an execution error):

the status of the function block outputs remains the same as it was during the previous scanning cycle that executed correctly;
the output(s) of the function, as well as the procedures, are set to "0".

WORD

The type WORD is encoded in a 16 bit format and is used to perform processing on series of bits.
