2.1.1.3 Description

This interface allows the connection of any device which is equipped with a

RS 232 C serial interface.

The wiring to the communication partner is made by the connections TxD,

RxD, if necessary RTS and CTS as well as ground (earth).

The shield (screen) is directly connected to the carrier rail.

The interface works in accordance with the TIA/EIA-232-F, CCITT V.28/DIN

66259-1 standard.

The connected device may directly communicate over the fieldbus coupler/-

controller with the control unit. The active communication channel works

independently of the higher-level fieldbus system and allows full duplex

operation up to 19200 baud.

Three green LEDs signal readiness for operation and troublefree internal bus

communication as well as the condition of the signal transmission.

The RS 232 interface guarantees high interference immunity because of the

electrically isolated signals.

Any configuration of the specialty modules is possible when designing the

fieldbus node. Grouping of module types is not necessary.

Attention

This module has no power contacts. For field supply to downstream I/O

modules, a supply module will be needed.

The serial interface module 750-650 and its variations can be used with all

couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy

types 750-320, -323, -324 and -327).

This description is valid from hardware and software version XXXX4108...

and up. The version is specified in the manufacturing number, which is part of

the lateral marking on the module.

WAGO-I/O-SYSTEM 750 System Description

2.1.1.7 Functional description

The interface module is designed to operate with all WAGO I/O fieldbus

couplers. The serial interface module allows the connection of RS 232-

Interface devices to the WAGO I/O SYSTEM. The RS 232 Interface module

can provide gateways within the fieldbus protocol. This allows serial

equipment such as printers, barcode readers, and links to local operator

interfaces to communicate directly by the fieldbus protocol with the PLC or

PC Master. This module supports no higher level of protocol. Communication

is made completely transparent to the fieldbus allowing flexibility in further

applications of the serial interface module. The communication protocols are

configured at the Master PLC or PC.

The 120 byte input buffer provides for high rates of data transmission. When

using lower rates of transmission speed you can collect the received data, with

less priority, without loosing data.

The 16 byte output buffer provides for faster transmission of larger data

strings.

Attention

The data transmission takes place at 9.600 baud. 1 startbit, 8 databits and 1

stopbit will be transmitted. No parity is available. The user controls data via

the RTS and CTS signals. These signals are generated in the module

depending on the loading status of the buffers. These controls can be

deactivated by means of an external jumper. RTS and CTS are to be

connected.

Attention

For testing purposes the Windows terminal emulation can be used. A

cable with a 9- pole sub-D socket is required. Pin 5 is connected to input

"common". Pin 2 is connected to TxD and Pin 3 to RxD. RTS and CTS of

the module are connected. A hardwarehandshake between the terminal

emulation and the PLC is not possible.
