6.3 Programming via the RS232 interface

When the RF1040R/RF1070R readers are connected to a SIMATIC controller,

communication takes place via the freeport protocol. The freeport protocol allows you to

communicate with the reader directly on the lowest level. A USB connection is not required

for this.

The telegrams are listed in a byte coding in the following sections; you can apply the byte

coding directly to the user program of the controller.

The communication parameters of the RS232 interface of the reader are set as follows in the

factory:

● Data bits: 8

● Parity: None

● Stop bits: 1

● Transmission speed: 115.2 kBd

Connection via a communications module or serial module

The reader can be connected to a SIMATIC controller using a communications module with

RS232 interface (e.g. RF170C). With a connection via the CM, you need to set the

communication parameters of the CM as follows:

Table 6- 18 Setting options in the "Module parameters" parameter group of the CM when using the

freeport protocol

Description

User mode Ident profile/RFID stand-

ard profile

FB 45 / FC 45

Selection of the block with which you want to

assign parameters to the reader.

MOBY mode Freeport protocol The parameter value "Freeport protocol" must

be selected in this parameter.

Transmission

speed

115.2 kBd The parameter value "115.2 kBd" must be se-

lected in this parameter.

Diagnostic

messages

None

Hard errors

Selection of whether hardware diagnostics mes-

sages are reported.

Suppression of

error LED

None

Channel 1

Channel 2

Selection of whether the error LED (ERR) of a

channel is suppressed.

Interface RS232 The parameter value "RS232" must be selected

in this parameter.

Alternatively, the connection can be made using a serial module with RS232 interface and

P2P communication (e.g. ET 200SP CM PTP).
