Function block L_IO1000_EPMS640_RS232Write

Function library: L_SM3_DriveUtil.lib

This function block coordinates the data transmission of the EPM-S640 I/O compound

module via RS232.

Inputs (VAR_IN)

Designator / Data type Info / Setting options

xExecute / BOOL A positive edge at the input triggers a request, i.e. the defined data

are transmitted by the EPM-S640 I/O compound module. A reset of

the input during processing does not affect the request.

After executing the current request, the block is reset with xExecute

=FALS“ and xReset=FALS“ and prepared for a new reset / data request.

xReset / BOOL A positive edge at the input triggers a reset of the EPM-S640 I/O

compound module which reinitialises the module. A reset of the

input during processing does not affect the reset.

After executing the current request, the block is reset with

xReset=FALSE and xExecute=FALSE and prepared for a new reset /

data request.

Notes:

Prior to the first data transmission, the user has to execute a reset!

This reset is a synchronous reset, i.e. when executed on the write

block, the EPM-S640 I/O compound module will be reinitialised both

for data transmission and for data reception.

If a reset and a data request are triggered at the same time, the reset

(having the higher priority) will be executed.

A reset can also be executed during an active request. In this case, it

assumes the function of a request abort.

pbyInput_address /

POINTER_TO_BYTE

Start address of the of EPM-S640 I/O compound module's input area

in the process image.

The address must be transferred with the ADR operator.

Example :"… pbyInput_address:=ADR(%IB4800) , …"

pbyOutput_address /

POINTER_TO_BYTE

Start address of the EPM-S640 I/O compound module's output area in

the process image.

The address must be transferred with the ADR operator.

Example: "… pbyOutput_address:=ADR(%QB4800) , …"

pbyData_address /

POINTER_TO_BYTE

Start address of the data area for data to be transmitted.
